Posted by: mschere New Fundamental Patent Issued... United States Patent 7,061,427 Hoffmann , et al. June 13, 2006 Directional antenna physical layer steering for WLAN Abstract
BACKGROUND OF THE INVENTION
Indeed, at the present time many laptop computers are shipped from the factory with WLAN interface cards. Certain microprocessor manufacturers, such as Intel, have also announced intentions to incorporate WLAN capability directly into processor chip platforms. These and other initiatives will continue to drive the integration of WLAN equipment into personal computers of all types. It is already the case that in many cities, WLAN access equipment operating in accordance with the IEEE 802.11a, 802.11b, and 802.11g standards is in wide use. In these cities one can now find "hot spots" that provide network connectivity. Unfortunately, having tens, if not hundreds, of closely spaced wireless networks using the same radio spectrum means that interference becomes a problem. That is, although the 802.11 standards provide for robust signaling in the form of spread spectrum radio frequency modulation, and using orthogonal frequency division multiplexing over modulated subcarriers, crowding of the radio spectrum still increases noise and therefore decreases performance for all users. It is recognized that directional antenna arrays can be used to steer radio frequency energy between a transmitter and receiver. This greatly reduces the amount of interference that would otherwise be created for concurrent users of the spectrum. The use of such arrays in wireless subscriber equipment has been described in U.S. Pat. No. 6,100,843 entitled "Adaptive Antenna for Use in Same Frequency Networks"; U.S. Pat. No. 6,400,317 entitled "Methods and Apparatus for Antenna Control in a Communications Network"; and in U.S. Pat. No. 6,473,036 entitled "Method Apparatus for Adapting Antenna Array to Reduce Adaptation Time While Increasing Array Performance". Each of these patents is assigned to Tantivity Communications, Inc., the assignee of the present application However, WLAN signaling has special considerations in that communication is expected to be on a peer-to-peer basis with extremely short packet lengths. It has heretofore been thought quite difficult to require WLAN subscriber equipment to steer an antenna array, to one of many possible candidate angles, during such very short intervals. SUMMARY OF THE INVENTION The present invention is a technique for implementing an antenna steering at the physical layer of a Wireless Local Area Network (WLAN) device. Implementing the antenna steering decision at the physical layer eliminates involving higher communication layers, which would otherwise require modification of standardized communication processing software, such as the Media Access Control (MAC) or Link layers. In one embodiment, the invention provides techniques for signal detection during short sync symbol reception in the very beginning of a preamble portion of a WLAN frame. Specifically, in the context of an 802.11a or 802.11g Packet Protocol Data Unit (PPDU) frame (packet), this may be concluded within only a few initial training sequence symbols of the Physical Layer Convergent Procedure (PLCP) preamble portion. Operating very quickly during these so-called short sync pulses, the antenna will be steered to an optimum direction prior to receiving other portions of the preamble. This permits the radio receiver equipment to use the remainder of the preamble to acquire carrier phase lock and frequency synchronization, in just about the same manner as if no directional antennal were present. The remaining preamble portions can thus be processed according to standard WLAN frame processing. One specific technique employed is to set an antenna array to an omnidirectional mode prior to reception of the first short sync pulse. This permits Automatic Gain Control (AGC) circuitry in the receiver to track for an initial short sync pulse. During reception of the next one or two short sync pulses, a signal metric such as a correlation is used to evaluate the observed response against an expected response. The expected response can either be a stored response that is the optimum expected for a short sync. Alternatively, the expected response can be a stored version of a measured response received with an omni setting during the initial short sync pulse. In accordance with certain other aspects of the invention, correlations can be performed over a first and second half of a short sync pulse by swapping real and imaginary samples. This provides twice as many candidate angles to be tested for each subsequent short sync pulse. With either of these two techniques, by the time of arrival of the fourth short sync pulse, the antenna array has been steered to a candidate direction. This provides at least five to six additional short sync pulses that may be used by the receiver to acquire frequency and phase lock. A third technique involves the use of finite impulse response comb filtering. This may be performed through the use of inverse Fast Fourier Transforms. The process here is to implement an ideal comb type filter response for both signal and noise and then convolve it with the received short sync signal. An approximate estimate of a signal to noise ratio can be derived as a ratio of observed signal and noise filter responses. The candidate angle exhibiting the strongest signal to noise ratio is then selected to be used. mschere
Posted by: lastchoice Verizon Wireless to Launch Mobile Chaperone Service By REUTERS NEW YORK (Reuters) - Verizon Wireless, the No. 2 U.S. cellphone service provider, plans on Monday to launch a wireless service that lets parents check their children's whereabouts and alerts them when they venture out of bounds. Parents can use the service to set up geographic limits and receive text alerts if their children, who also carry phones, go too far from home. The service also lets parents check where their offspring are via a map on their cellphone or computer. The Chaperone-branded service from Verizon Wireless, a venture of Verizon Communications (VZ.N) and Vodafone Group Plc (VOD.L), follows in the footsteps of a similar service that Sprint Nextel Corp. (S.N) introduced in April. Entertainment conglomerate Walt Disney Co. (DIS.N) is also set to offer a similar service when it starts selling cell phones this summer.
Mobile packages designed for families have become key to growth at U.S. operators, which currently sign up as many as 60 percent of their new subscribers via family discount plans, according to technology research firm Yankee Group. Verizon Wireless did not say how many of its customers have children in the 5-year-old to 9-year-old target market but an executive concurred with the Yankee estimates on family plans and said the market for this service could be big. ``You're looking at a good percentage of customers that have families with children,'' said Jamal Jones, Verizon Wireless manager of consumer products, in a conference call with reporters on Friday. The Verizon service costs $9.99 a month for just the location-viewing feature and rises to $19.99 a month if the parent also opts for a boundary-setting feature. Sprint charges about $9.99 for its service. Verizon is initially launching the service just for parents with children using the Migo phone from LG Electronics Inc (066570.KS), a four-button phone designed especially for children. Verizon started selling the Migo in November. Executives said Verizon Wireless may develop a version of the service for older children, using more sophisticated phones, but they did not give details. Parents can access the service using about 10 different phone models sold by Verizon Wireless including several phones from LG and some phones from Motorola Inc (MOT.N) and Samsung Electronics Co Ltd. (005930.KS). Billion--with a 'B'
-abridged post- Glitch-free World Cup seen key to mobile TV future By Santosh Menon
Mobile operators across the world, especially in Europe, have laid out grand plans to show the soccer games on phones, some broadcasting them live to consumers as the industry continues to attempt to extend the limits of cell phones. Analysts say using the World Cup as a hook to boost mobile TV services is a sound bet, given the popularity of the event worldwide and its potential to appeal to a mass market. But the margin of error available will be thin. "People will approach it with high expectations and a great deal of passion, so operators must get it right ... A poor service experience for such an event will tarnish peoples' impression of mobile TV," said Ovum analyst Eden Zoller.
Its success is particularly important for operators in highly saturated western European markets, where revenue growth and profits are falling because of intense competition and threats from cheaper technologies. Industry analysts say a lot will rest on the month-long championship, which got underway in Germany on Friday. CATALYST "This year's World Cup will prove a major catalyst for mobile TV growth. It will give operators a chance to show what they can already do and test consumer demand," says David McQueen, senior analyst at Informa Telecoms and Media. Informa has forecast revenues of $300 million from users accessing streaming and broadcast World Cup games and services. However, live broadcasts of World Cup games on mobile phones will not be available to the wider market, with choice of handsets limited, most operators still in the midst of trials and wider issues such as radio spectrum still to be resolved.Around 30 mobile TV trials are underway, most of them involving the Digital Video Broadcasting-Handheld or (DVB-H) technology.
This time around, the bigger test will be in proving television works on mobiles. IDC analyst Paolo Pescatore said the World Cup was a showcase "to show users the power of mobile." "But the real growth will take place over the next five years," said Informa's McQueen. "As soon as the 2008 Olympics, we'll all be much more prepared to watch TV on our phones and by the 2010 World Cup the infrastructure will be mature and one in 13 mobile phone users worldwide will own a mobile TV handset."
Gamco Posted by: mschere Free WiMAX ...forever? 9 Jun 2006 The Carphone Warehouse raised a few eyebrows when it announced that it would be giving away free 8Mbps broadband to UK customers signing-up to its residential telephone service – “Free Broadband ...Forever”, the ad campaigns shout. This week, Charles Dunstone, the company’s CEO, announced that, in the six weeks or so since its launch, some 340,000 customers have already signed-up for the Talk Talk offering: vastly exceeding the 170,000 punters the company had expected. There are now rumours that Dunstone is looking to acquire AOL’s British division to quickly ramp his business - AOL is the third largest ISP in Britain, after NTL and BT, with 2.2 million customers. Dunstone freely admits that Talk Talk will initially lose money, but the strategy is to grab customers today, with the intention to offer media, entertainment and communications services in the future, which can be charge for at a premium.
Rarely in the consumer world do you find such huge disparities between two providers of the same product, and nothing highlighted this more than holding the two brochures together side by side. Purely from a consumer perspective, it is really difficult to see how Now’s slower wireless service can compete in a market where there is ruthless competition amongst DSL and cable broadband providers. There will certainly be some consumers who will be attracted to Now’s lower cost, although any who go online and do their homework will discover that Bulldog also has an 8Mbps service for just £9.50 a month (but with a 1Gb cap). They would also discover that Bulldog are now offering 16Mbps for the same £19.50 a month (for a promotional period), while Now is offering 1Mbps for £18 a month. Why would anyone chose Now? The Now broadband service is operated by UK Broadband, a wholly owned subsidiary of PCCW, the Hong Kong-based fixed and mobile telecoms operator which owns a 3.5GHz license in the UK. The UK Broadband service is based on the UMTS-TDD wireless standard, with equipment provided by IPWireless, and the operator has large parts of South East England covered. On its website, Now boasts that its service is ‘wireless’ and can be used anywhere within the home; but, of course, it doesn’t say that you can do exactly the same with DSL plus Wi-Fi, and at lower the cost. However, Now’s proposition descends into farce as I go through the sign-up process: the website asks what floor I live on, and I discover that I am unable to register if I live on the ground floor or in the basement of my building – it only allows me to sign-up if I live on the first floor or above. It’s so sad it hurts a little. I wonder what consumers would make of this since few will be able to comprehend the technical reasons for this. Not all London properties have a basement, but they all have a ground floor. The competitive situation in London between fixed and wireless broadband providers highlights what awaits WiMAX operators hoping to launch services in urban areas. There is no doubt that BWA operators will find an addressable market in areas poorly served by copper – as demand for broadband explodes, they will more or less be able to dictate prices in these locations. But this does not justify deploying a national WiMAX network. On the other hand, mobile WiMAX, or WiBro (since the two are likely to be the same), has the advantage of mobility, but this shifts the technology into the crosshairs of cellular – namely mobile broadband technologies like HSDPA and EV-DO. If we ignore for the moment that many regulators still do not allow mobility in their selected BWA spectrum bands (e.g. many Europeans in 3.5GHz) the fact is that, in developed markets, when mobile WiMAX networks are eventually deployed, they will do so in areas which have had cellular broadband coverage for at least a year; and likely longer. So, again, the question is: what is the business model? One answer is that, with WiMAX embedded into portable devices, operators will not have to support the cost of customer equipment (CPE), substantially reducing their overheads. However, while Intel will have us believe that WiMAX laptops will arrive next year, the reality is that these are unlikely to ship in volume until 2008/9, and the same is true for WiMAX handheld devices. At this stage, WiMAX will compete with cellular mobile broadband in the wide area, fixed Wi-Fi broadband in the wide area (hotspots and hotzones) and fixed Wi-Fi in the home and office; and these latter two technologies (Wi-Fi and HSDPA) are already being integrated within the same handset today. This is not to say that WiMAX will never be deployed alongside HSDPA and Wi-Fi. It certainly will. However, it will simply be exploited as another bit-pipe through which the likes of the Carphone Warehouse will pump their value-add content and services – “Free WiMAX ...Forever!”. The winners will be consumers, who’ll get dirt cheap bandwidth. The losers will be the companies who saw WiMAX as the wireless panacea that would be the next great telecoms cash cow. mschere
Posted by: Learning2vest FWIW, I still see personal identity as the "next big thing" in mobile phones. I know, LOL! "Say What?"... Mobile phones are already pretty sophisticated computing devices, and they are capable of talking to other computers in a much more secure way than anything else we use to conduct our personal financial transactions today. You can get knocked over the head for carrying too much cash, checks get forged, and identity theft is a big worry with credit cards and e-bills. I'm looking forward to the day when my "identity" can be consolidated into a mobile computing device so that no transactions happen in any of my personal accounts without my authorization.
THAT is going to be a "killer" application IMO. Once one bank in partnership with a mobile operator offers it, they ALL will be scrambling to catch up. Good by checks, credit and debit cards, and most of the cash. Hello personal identity device. It will be a "converged" device using cellular modes to stay in touch with the network attached computers where I have accounts(i.e., my bank, broker, and the folks that I buy stuff from on a regular basis), bluetooth for ad-hoc retail transactions, and maybe even WLAN for some things.
-abridged post- Posted by: mschere IDCC also targets CONVERGED Devices in its new Business plan. Analysis: Nokia's new CEO - who is Kallasvuo? By Jo Best Published: Friday 9 June 2006 Olli-Pekka Kallasvuo has been in his new job for one week. He is one of mobile's most powerful men and he'll be following in some very impressive footsteps. But who is he? After more than a decade of leading the world's largest mobile phone company, Jorma Ollila stepped down from his CEO role this month (he is now chairman at Shell) and handed over control to 52-year-old new boy Kallasvuo. Unlike Ollila, Kallasvuo has a legal background, graduating in law at Helsinki University and joining Nokia initially as corporate counsel. But that's where the differences stop.
The pair have a long history of co-operation. During his tenure Ollila relied on a number of key execs charged with helping him get Nokia back on its feet. Of that group, only Kallasvuo is still at the company. With a long and parallel history, it is tempting to see Kallasvuo as Ollila Mark II. While it is widely expected that he will try to follow in Ollila's still-warm footsteps, looking to build market share and trimming the operational fat, OPK has already made his own fair share of headlines. He's already announced the company is likely to be more acquisitive and look to enter into more partnerships. He has also attracted his own fair share of headlines by neglecting to pay tax on some luxury goods and attracting a €31,000 fine. Kallasvuo certainly seems to be a man not afraid of talking big. In recent interviews, he has been positioning the company outside the mobile phone business - as convergence brings more and more technologies onto the humble mobile, Nokia is lining up to become a consumer electronics, not a pure-play mobile, company. After all, Nokia is now the largest manufacturer of cameras. Why not the future 800-pound gorilla of MP3 players or TVs (though it has already entered and exited the latter area once before)?
Kallasvuo will also inherit Nokia's problems - the US being one of the most notable. Kallasvuo's experience will come in handy here, as he's previously headed the company's US division. During his States sojourn, Kallasvuo managed to win back crucial market share but since his departure, Nokia has once again slipped into second place, behind Motorola. mschere
Bill, Here is what (IDCC CEO Bill Merritt) had to say in the 3/09/06 conference call. When you combine the comprehensive nature of that offering, with the challenge that many market participants have faced in 3G development, we believe we have an excellent opportunity to gain meaningful market share and revenue. To further enhance the likelihood of our success with that offering, we intend to bring it to market in three complementary ways. The first market channel would be for offering a comprehensive set of technology blocks to the major semiconductor companies. We are already seeing a significant level of market interest in our offering.
The second market channel would be bundling as appropriate our terminal unit technology solutions with our patents and offering that bundle to major handset suppliers, either on our own, or in conjunction with a semiconductor partner. So, as an example, if a major handset company needs a 3G handset platform, which includes the reference design, basic software and all of the peripherals, we would work with one of our semiconductor partners to deliver to that manufacturer both the platform and a patent license on attractive combined economics. Or, if a handset manufacturer has a platform and the internal capability to develop and produce ASIC, we'd work with that manufacturer to develop its own internal 3G ASIC solution, and at the same time resolve any potential patent licensing issues.

Netcom Africa, IP communications provider, has continued to expand its subscriber base with its MyNetcom wireless broad band product which uses the Universal Mobile Telecommunications System (UMTS) and Time Division Duplex (TDD) wireless broad band technology.
Posted by: my3sons87 Panasonic 3G Phone Shipping Panasonic Mobile says that it has begun shipment of "FOMA P901iTV" mobile handsets to Japan's DoCoMo. The P901iTV is NTT DoCoMo's first mobile handset to receive terrestrial digital broadcasting signals in addition to conventional analog signals. The handset was created in response to the planned launch of mobile digital broadcasting in April 2006.
The P901iTV focused on user-friendly features which customers value the most. By turning the highly flexible antenna towards the right angle, users can enjoy watching TV programs. In addition, users can instantly start watching TV by either pressing a TV button or only turning the handset head towards the 90 degree angle. Depending on the handset angles, the P901iTV display screen automatically rearrange its direction, from right to left or top to bottom, to best fit for the viewing.
Posted by: MSC290 Buy or wait: 3G phones . . . By Jørgen Sundgot, Thursday 1 June 2006 - infosync Choice has never been better in the world of 3G phones, but HSDPA handsets – which offer up to six times faster download speeds – are poised to hit shelves this summer. Should you save up for one? Gone hunting for a new 3G phone lately? If so, you're likely to have noticed the overwhelming array of options – and despite our guide on what to look for and our list of top rated 3G phones, one more factor is looming on the horizon that you might want to take into account. We're talking about HSDPA, or High Speed Downlink Packet Access, which bumps the average transfer speeds of current 3G phones by a factor of six – enough to download your average MP3 file in less than 10 seconds. Acronyms schmacronyms
As of this writing, Cingular is the only U.S. operator that offers HSDPA coverage; its “BroadbandConnect” service covers 16 cities, including Austin, Baltimore, Boston, Chicago, Dallas, Houston, Las Vegas, Phoenix, Portland, Salt Lake City, San Diego, San Francisco, San Jose, Seattle, Tacoma, and Washington D.C. Cingular has yet to launch an HSDPA-capable handset, although we expect the high-speed Samsung SGH-ZX20 clamshell – poised to be the first commercially available HSDPA phone in the U.S. – to arrive in Cingular’s lineup soon. Meanwhile, GSM carrier T-Mobile, which is the only major U.S. carrier still without a 3G network, has announced plans to launch its own HSDPA service by the end of 2007.
The average Joe, meanwhile, is unlikely to benefit at all from first generation HSDPA phones for several reasons. First, initial coverage will be poor and limited to dense urban areas, and there will little content that takes advantage of the added bandwidth – such as higher-resolution video – until at least 2007. Second, unless users are on a flat rate data plan with their operator, they will be unable to consume much content without going broke in the course of a month. The bottom line In summary, unless you're filthy rich or a business user with a proven need for downloading large amounts of data faster, there is no need to rush to get a HSDPA phone. Rather, save your pennies for a more capable 3G handset; we also suggest mastering the delicate art of getting the most out of your 3G phone. http://www.infosyncworld.com/news/n/6766.html
there won't be any circa 1995 nokia's with 40% (maket share) ever again! first the japanese, then the taiwanes, then the chinese and then the indians... another beauty of the standards bodies. intellectual property is the place to be!

WiBro to Meet Cell Phone
By Kim Tae-gyu
KT, the nation's fixed-line telecom giant that is developing WiBro services, Tuesday said it aims to employ a terminal that can be used for both WiBro and CDMA-based mobile calls by late this year The convergence device, called the dual-band-dual-mode (DBDM) terminal, will be developed by Samsung Electronics, the world's No. 3 cell phone maker. ``The development of the convergence terminal is now underway with the aim of releasing it commercially this year,'' said a senior KT official, who declined to be named.``The advent of the DBDM device would raise the viability of WiBro by allowing users on the go to access to the Internet and make phone calls with a single gadget,'' the official said. He added the all-in-one gizmo would look like a personal digital assistant and would be equipped with Korea's homegrown software such as wireless Internet platform for interoperability, or WIPI, a must for the go-anywhere Internet services. Korea has taken the driver's seat in launching every version of CDMA over the past decade although the technique is the offspring of the U.S.-based Qualcomm. After Korea proved the rich potential of CDMA, other countries including Japan, China and the United States embraced the cellular platform later. By contrast, WiBro is made-in-Korea technology with which people on the road can remain hooked up to the Internet at the speed of the current fixed-line broadband. KT started a pilot run of the locally developed application this March and is poised to commercially kick-start the mobility-specific offering late next month. Another WiBro licensee, the country's foremost wireless operator SK Telecom, is seeking to follow suit. The KT official expected the unprecedented combination of CDMA and WiBro would not be difficult in terms of technology and regulation. In addition to giving mobile phones WiBro applications, KT is looking to add other features such as mobile broadcasting in the not-so-distant future for the so-called triple-band-triple-mode device. ``It is a long-term consideration after completing the DBDM phone this year. The third feature can be anything and one of the powerful candidates is free mobile broadcasting,'' the anonymous KT official said. Korea already has high-quality, free television-on-the-move services in the terrestrial digital multimedia broadcasting (DMB) that became available in Seoul and its vicinity beginning last December. The KT plan is in tune with the projection of Samsung Electronics, one of the world's most advanced high-tech companies. ``Over the long haul, all imaginable handheld terminals and home appliances will be incorporated with terrestrial DMB,'' Samsung vice president Lee Kyung-ju said http://times.hankooki.com/lpage/200605/kt2006053017172010220.htm
Posted by: Bill Dalglish Oh, oh! Significance of OFDM and MIMO Are our more tech oriented folks here suggesting that the very new wireless technologies, OFDM and MIMO, NOT an evolution of UMTS/WCDMA (3G) - but something entirely different? Like WDCMA or Qualcomm's CDMA 2000 were not an evolution, but something entirely different than 2G's GSM or TDMA? That's darn radical stuff, then. Is that why Release 7 of standards won't have CDMA as the foundation? (We are implementing Release 5 or below, now, I understand) So if OFDM/MIMO becomes the norm for 2012 and beyond, then it truly becomes 4G? And HSDPA and HSUPA are perhaps 3.5G and 3.7G? Where do WiFi and WLAN and related technologies fit in the "evolution" or a "new beginning" in wireless communications? Is this why IDCC is apparently seeking a place in the OFDM and MIMO standards under development? (Of course, 4G might be something entirely different than OFDM/MIMO, right?) Even if IDCC ends up with no essential patented tech in a totally new generation (eg 4G), I assume royalties for 3G come in for some time after 4G arrives because 4G devices have to communicate with the air interface of 3G (as 3G does to 2G). Is that a fair assumption? This is some pretty radical long term stuff to think about. This would help explain why Nokia and other top tier manufacturers are hinting about wanting to design around CDMA and QCOM's lock on 4-5% CDMA royalties? Thanks to those of you who already grasp these implications and are sharing your insights here. This is looking like an "ah-hah" moment for me. Bill

One building block for next-generation wireless access, MIMO (multiple-input, multiple-output), is an advanced antenna technology that can carry 4 to 5 times more data traffic than today’s most advanced UMTS-HSDPA-ready (3G) networks. A network design incorporating MIMO technology provides the scalability needed to quickly deliver multimedia content to the mass market. With MIMO, for example, a ½ megabit picture can be downloaded in a half second or a 30-megabit video in half a minute. MIMO works by creating multiple parallel data streams between the multiple transmit and receive antennas (see figure below). Using the multi-path phenomenon, it can differentiate the separate signal paths from each MIMO antenna. Thinking back to the highway example, MIMO effectively adds several new highways. OFDM has some key advantages over the common wireless access technology known as CDMA, which is used in many of today’s 3G cellular networks. To begin with, it is more robust, which means that it provides better performance in cluttered areas with many reflections (multipath). It also allows for simpler receivers. Perhaps most important, OFDM is more amenable to MIMO technologies.

Recognizing the need to continue to improve data rates, coverage and capacity, work is underway within 3GPP on further evolution of the standards. Release 7 is expected to address incremental performance improvements. In addition, a longer term initiative known as Evolved UTRA/UTRAN (UMTS Terrestrial Radio Access/ UMTS Terrestrial Radio Access Network) is underway. The objectives of this initiative are more ambitious, targeting peak data rates of 100 Mbps in the downlink and 50 Mbps in the uplink, improved spectrum efficiency, significantly reduced data latency, and scaleable bandwidths from as low as 1.25 MHz to as high as 15 MHz. We are participating in Release 7 and evolved UTRA/UTRAN standards activities and have launched internal projects to develop the technology necessary for the new performance requirements. Perhaps you are not aware that "Evolved UTRA/UTRAN is LTE?

Posted by: mschere I imagine that you never read IDCC's last 10K Release 6 of the FDD standard introduces HSUPA. HSUPA increases the uplink rate to a theoretical maximum of 5.8 Mbps. Release 6, which includes both HSDPA and HSUPA, is poised to support high speed data in both the uplink and downlink, reduce the latency in data transmission, and increase overall network capacity. In addition to HSUPA, Release 6 adds MBMS (Multimedia Broadcast Multicast Service) functionality which is a means to provide subscription and non-subscription based broadcast services in 3G cellular networks. Our current efforts include upgrading our Release 5 technology to Release 6, phasing the additional features into product offerings according to projected market acceptance.

For example, national and international university relationships have provided us additional opportunities to explore new technologies and license intellectual property advancements that we sponsor. We maintain an active corporate development program that seeks further investment opportunities in technologies that can enhance the attractiveness and profitability of our technology solutions. We have also engaged in selective acquisitions to enhance our intellectual property portfolio and/or accelerate our time-to-market. For example, in July 2003, when we acquired substantially all the assets of Windshift Holdings, Inc. (formerly known as Tantivy Communications, Inc., “Windshift”) we acquired patents, patent applications, know-how, and other assets related to cdma2000, smart antenna, wireless LAN and other wireless communications technologies. In addition, in first quarter 2005, we acquired, selected patents, intellectual property blocks and related assets which are designed to improve the range, throughput and reliability of wireless LAN and other wireless technology systems. IMO:Patent 7031669 appears to be a valuable Release 7 OFDM/Mimo asset SUMMARY OF THE INVENTION Briefly, techniques are provided to correct for phase and amplitude mismatches (also referred to herein as offsets or imbalances) in a device in order to maintain channel symmetry when communicating with another device using MIMO radio communication techniques that depend on channel symmetry. Correction for the amplitude and phase mismatches among the plurality of transmitters and plurality of receivers of a device may be made at baseband using digital logic (such as in the modem) in the receiver path, the transmitter path or both paths of that device. In a device, amplitude and phase offsets are determined among the plurality of radio transmitter and radio receiver paths by measuring phase and amplitude responses when supplying a signal to a transmitter in a first antenna path of the device and coupling the radio signal from a first antenna to a second antenna path of that device where the signal is downconverted by a receiver associated with the second antenna path, and similarly measuring phase and amplitude responses when coupling a signal from the second antenna path to the first antenna path. Measurements are obtained between the first antenna path and each of the other antenna paths when coupling a signal in both directions between them. Phase and amplitude offset correction values are computed from the phase and amplitude measurements during a self-calibration operation or mode of the device, and are used during a run-time operation or mode when processing the baseband transmit and/or receive signals to compensate for the phase and amplitude offsets among the plurality of transceiver paths of a device. Amplitude offset correction may not be necessary (or optional) for certain radio implementations or MIMO radio algorithms. The device may execute the self-calibration mode on device power-up, and then periodically thereafter. Self-calibration may also be performed at the factory on a device. When a first device calibrated as described herein communicates with a second device similarly calibrated, the channel response between the digital input (DAC input) of the transmit paths of the first device to the digital output (ADC output) of the receive paths of the second device is symmetrical to the channel response between the digital input (DAC input) of the transmit paths of the second device to the digital output (ADC output) of the receive paths of the first device. Thus, the channel responses between the two devices at the baseband signal processing level are symmetrical, which is desirable for MIMO radio algorithms that depend on channel symmetry. These techniques are useful for single carrier modulation systems as well as multi-carrier modulation systems, such as an orthogonal frequency division multiplex (OFDM) system. Advantages of the present invention will become more apparent when reference is made to the following description taken in conjunction with the accompanying drawings. mschere
What's behind Qualcomm's Flarion acquisition? Earlier this week, Qualcomm resolved an issue with the U.S. Justice Department concerning its acquisition of Flarion. By Gurinder Dhillon, Airgo Networks Flarion’s acquisition by Qualcomm shows Qualcomm’s desire to build its IP portfolio and position itself for the 4G technology. Early on, Qualcomm tried to portray the superiority of CDMA technology for 2G and 3G networks over GSM. It succeeded in many areas except Europe. Using its patent position in CDMA, Qualcomm gained significant financial advantage. More recently, the cellular industry has opposed Qualcomm’s IPR tactics Qualcomm has legal battles regarding its IPR policies (e.g. Nokia and others filed a complaint with European Union over excessive IP costs, Broadcom/Qualcomm suits and counter suits, etc.) These developments show how aggressive Qualcomm is in extracting revenues from IPR and also protecting it.
Qualcomm will try to leverage the Flarion technology for the 802.20 standard and position it as a competitor to Intel supported WiMAX technology. Also, Qualcomm did not have a strong patent position going into the 3GPP LTE standard that is expected to be based on OFDM. Companies such as Nortel, Samsung, etc. have aggressively supported OFDM and have patents in this area. Flarion patents help Qualcomm in increasing its patent portfolio in OFDM area that would not even come close to what they have in CDMA OFDM is a combination of FDMA and TDMA. RE: mschere
Posted by: mschere LTE will be based on many elements that will be included in Release 7 of the 3GPP standard, primarily OFDM and MIMO, although CDMA technology will be removed from Radio Layer 1 of LTE. Draft specs for Rel. 7 are due to be frozen in June this year. "It is unlikely all vendors will agree to IPR capping," says Patterson. "Nevertheless, by removing CDMA from the LTE standard it also removes perhaps the most vocal opponent to royalty capping and proportionality - Qualcomm." At the end of last year, Ericsson, Nokia, Texas Instruments, Broadcom, NEC and Panasonic each filed separate complaints with the European Commission requesting that it "investigate and stop Qualcomm's anticompetitive conduct" in the licensing of essential patents for WCDMA technology. None of the complainants doubts that Qualcomm owns essential IPRs to the WCDMA standard, but they claim it has not contributed as much to that standard as it did to the development of CDMA and cdma2000 and, therefore, should not charge the same royalty rates for WCDMA as it does for CDMA and cdma2000. The EC is expected to publish an initial decision on the complaints within the next few weeks, and is widely expected to order a more detailed investigation, which could take a few years to complete. With some 40 companies already believed to be holding essential WCDMA IPRs, the industry push toward multiple radio-access technologies and multimode handsets could see the number of essential IPRs skyrocket. "Estimates for cumulative royalties for WCDMA are between 25% to 30% and the mobile industry could spend US$80-100 billion on WCDMA-IP-royalty payments up to 2017," says Patterson.
The Third Generation Partnership Program (3GPP) hopes to complete initial studies and have a workplan created for LTE in time for the TSG plenary meetings in June this year, although this may be delayed until September, with relevant specifications to be developed by June 2007 and the standard hopefully frozen by end-07 mschere

The next phase of the mobile revolution is about to begin. By Carlo Longino, Business 2.0 Magazine (Business 2.0 Magazine) - Want to get a sense of where wireless technology is headed? Think back to where the Internet stood at a similar point in its development - say, sometime around 1998. Back then the computer had already become a fixture in a majority of American homes, while the Web and e-mail were just beginning to reshape the way people interact, socialize, and shop. But better things were yet to come: At a time when 98 percent of Internet households still connected to the Net via dial-up modems, the telecom industry was spending billions to make broadband access more pervasive. Fast-forward to 2006. Today, 55 percent of U.S. homes have high-speed Internet access, and the industry is experiencing another wave of innovation as entrepreneurs create new products and services to exploit today's faster networks. Meanwhile, though more than half of all Americans now own mobile phones, most handsets are still limited by slow connection speeds. But this, too, will soon change. Three of the four major U.S. carriers switched on high-speed 3G networks in 2005, and Wi-Fi hotspots continue to proliferate, with places like Philadelphia and San Francisco planning to create citywide Wi-Fi networks. "We're connected in our homes. The next step is to be connected wherever we are," says Derek Kerton of wireless consultancy the Kerton Group. And that's only part of the story. Technologies like Wi-Max could introduce more competition by eliminating the advantages that telephone and cable companies now enjoy thanks to ownership of the wires that deliver broadband into homes and offices. Unlike a Wi-Fi hotspot, which provides wireless access within a radius of just a few hundred feet, Wi-Max creates a wireless cloud big enough to cover several square miles. "It's hard to get excited by the technology as it exists now," says James Enck, an analyst at Daiwa Securities SMBC Europe. "But when you look at everything that's happening, it starts to get really interesting." Put simply, we're on the cusp of a dramatic transformation that will extend far beyond the mere ability to download e-mail, photos, and webpages more quickly. Plentiful wireless bandwidth, coupled with more sophisticated mobile devices, will usher in a new generation of wireless tools and services. By clicking on the links (above), you'll get (links to) an advance look at some of the technologies that promise to make this new era of mobility truly revolutionary.
Posted by: Learning2vest moose, after reading your ref article I went to the IDCC website and could not find anything about the "I-CDMA" development program it talks about. Not sure if that means it is something still in active development or something that got mothballed with the other Tantivy product programs.

It also supports multitasking functions allowing users to receive and send messages during video telephony and while listening to MP3 files. Users can also enjoy watching mobile TV via Satellite Digital Multimedia Broadcasting (S-DMB) and take pictures with a high resolution 2 megapixel camera with auto focus function. It also offers other sophisticated multimedia features such as MP3 player function, text-to-speech (TTS) conversion, file viewer and supports an external memory (microSD) slot. Kitae Lee, president of Samsung Electronics' Telecommunication Network, said “Samsung is proud to launch the first HSDPA phone for Korean market. With the successful launch of future mobile broadband in our domestic market, we look forward to lead and expand HSDPA technology worldwide.” He added, “Our unique designs and cutting edge technology have made Samsung a top player in the premium phone segment. Now we shall demonstrate our full potential in the HSDPA area as well.” HSDPA, a new form of mobile broadband, is capable of transmitting data at speeds about seven to ten times faster than that of WCDMA. Users can enjoy large-scale multimedia downloads, such as DVD-quality movies and interactive multimedia games, with high-speed wireless Internet access comparable to speeds of fixed-line ADSL services. The launch of the Samsung's SCH-W200 marks the world's first commercial HSDPA services in cooperation with SK Telecom, Korea 's largest mobile service operator. Samsung will also be providing HSDPA handsets for KTF, Korea 's second largest mobile service operator, in June.
Posted by: lastchoice WiMAX Vendors Think About Qualcomm Royalties, says ABI Research OYSTER BAY, N.Y.--(Business Wire)--May 18, 2006--
WiMAX equipment vendors should begin now to factory royalties into their planning and pricing activities, according to ABI Research. The firm's newly-launched "Mobile Broadband Research Service" pinpoints a potential ongoing cost that is being widely ignored by the WiMAX industry, with one notable exception. Qualcomm has long been collecting royalties for its CDMA technology, and more recently for WCDMA as well. The company's pricing structure has led to a perception among some licensees that Qualcomm is focused on making royalties its primary revenue stream. Senior analyst Philip Solis of ABI Research's wireless connectivity practice says that is not the case, citing figures showing that IPR currently accounts for less than one third of the company's revenues. "Qualcomm will certainly continue to man the toll-booth, however,says Solis. "By acquiring Flarion Technologies recently, Qualcomm added significantly to its stable of OFDM-related patents, and the company will enforce them vigorously. That has a direct bearing on the plans of WiMAX vendors, who must factor these royalties into their business models." One WiMAX-oriented company, Soma Networks, has clearly been paying attention. Soma licensed Qualcomm's CDMA IPR in 2001, and announced last month that it had signed worldwide subscriber and infrastructure license agreements with the company, allowing it to develop, manufacture and sell OFDM/OFDMA subscriber units, modem cards and infrastructure equipment. This was the first such WiMAX-related royalty agreement concluded by Qualcomm. "Soma wants to remove uncertainties from its discussions with carriers," Solis concludes, "so it is clearing the air by paying royalties to Qualcomm." Soma has called the decision 'future-proofing our solution,' and it is a smart move. But its further impact is that Qualcomm will look to all WiMAX companies for royalties, using its agreement with Soma as a precedent. Industry-wide, this issue is being widely ignored. "WiMAX vendors may think that they don't have to worry about Qualcomm's OFDM patents," says Solis, "but they are mistaken: Qualcomm will enforce them."

Posted by: lastchoice Hard Drives in Cellular Handsets Could Spell the Beginning of the End for Portable MP3 Players, Says ABI Research OYSTER BAY, N.Y.--(Business Wire)--May 4, 2006-- Mobile phones offering generous data storage, enabled by small hard drives with ever-greater capacities, may soon allow the cellular handset to rival or surpass the portable MP3 player as the mass market mobile music device of choice.
At present, portable MP3 players still lead in their memory capabilities: high-end devices can hold as much as 30 or 60 GB. But Varghese believes there is a point of diminishing returns beyond which a user doesn't care whether the device can store 2000 songs or 7500. MP3 player vendors may try to defend themselves by offering even greater disk space, but over time they may still lose market share. Mobile operators are already setting up iTunes-like stores of their own to serve a public equipped with MP3-capable handsets. Additionally, given that most MP3 players are stocked primarily with songs from consumers' own music collections, rather than only those downloaded from an online music store, high-capacity MP3 handsets provide users with the flexibility of listening to those tracks on a device that's almost always with them. The latest update to ABI Research's subscription Wireless Semiconductors Research Service explores hard drives in cellular handsets as well as many other topics. This Service includes a variety of research reports, user-searchable forecast and industry databases, periodic market updates, ABI Insights and analyst inquiry time.

Posted by: mschere My comment..If IDCC were to sign Fujitsui 3G and provided amnesty for prior 3G sales, then the GURUS would almost be justified in talking about leaving $100 Million on the table... Fujitsu, 3G Technology Leader, Leverages Global Wireless Expertise to Offer New Broadband Wireless Options 5th April , 2006
To date, wireless access has been confined to proprietary solutions that fit highly specific applications. With the ratification of the IEEE 802.16 standard, technology unifies the underlying economics to transform the business case for broadband wireless access. WiMAX makes the broadband experience available both indoors and outdoors, enabled by hot zones that can be up to twenty times the size of traditional hot spots, and allows high-quality, multi-megabit services to be delivered wirelessly to end users at much higher speeds than is possible with voice-centric 3G networks. WiMAX will also bring broadband services to customers in rural or less densely populated areas where impairments with existing networks hamper DSL and cable modem deployment. Fujitsu offers a full breadth of flexible wireless solutions, including WiMAX System on Chip (SoC) and reference designs for WiMAX-certifiable systems. New WiMAX Forum Certified(TM) base stations and end-user devices are optimized for the delivery of scalable wireless bandwidth and Voice-over-IP (VoIP) services to residential and enterprise users. Initial Fujitsu WiMAX products will operate at 3.5 GHz, 4.9 GHz and 5.8 GHz, with plans to support 700 MHz, 2.3 GHz, 2.5 GHz and 3.65 GHz in the future. Advanced RF technology allows these products to feature a two to five mile service radius in urban/suburban environments, and services up to tens of miles away in line-of-site applications. The WiMAX products integrate Session Initiation Protocol (SIP) gateway messaging to enable call control and capacity reservation for voice traffic. Voice capacity is not reserved until requested, and can be dynamically adjusted while maintaining Quality of Service (QoS), thus enabling the optimal use of radio link capacity. Outdoor WiMAX products can be wall-, rooftop- or tower-mounted. The Wi-Fi mesh products are based on IEEE 802.11a/b/g, and the backhaul radios within them operate within the 5.0 GHz to 5.8 GHz unlicensed band for Wi-Fi. They can provide service within 500 yards in IEEE 802.11g mode, and can be wall-, rooftop-, tower-, pole- or strand-mounted for maximum flexibility. Fujitsu Network Life Cycle Services are available to assist carriers with end-to-end, turnkey solutions that simplify the deployment, upgrade, expansion, and migration of wireless networks. Extensive experience in providing leading-edge solutions within multi-vendor and multi-technology networks allows Fujitsu to offer a seamless systems integration experience. In this role, one partner can control all aspects of technology delivery from leading-edge systems development to optimal network deployment and maintenance. "With Wi-Fi, WiMAX and service solutions that leverage our global experience in fixed and mobile wireless technology, Fujitsu will continue to be the preferred business partner carriers turn to for innovative communications solutions," said Bill Erickson, senior vice president of sales and marketing at Fujitsu Network Communications. "Our blended portfolio of native and best-in-class partner products enables us to best support the entire wireless application space. These products provide a unique combination of features, economics and service propositions that bring inexpensive and ubiquitous broadband wireless access to residential and enterprise users. When carriers outsource their network services to us, they can concentrate on core business activities while we help them accelerate the introduction of wireless services to their customers." mschere Brian G.

Wireless Local Area Network (WLAN) equipment continues to be used as a solution for many different data connectivity applications. WLANs are now viewed as an ideal solution for providing access to wireless equipped personal computers within home networks, mobile access to laptop computers and personal digital assistants (PDAs), as well as providing robust and convenient access in business applications.
Such services are aimed at bringing in revenue from a location technology that U.S. wireless service providers are required by law to put into cell phones so that safety workers can pinpoint the location of 911 emergency service callers.
The World Cup may be the catalyst for the mobile industry to push TV services on phones and tap new revenue streams, but operators need to get it right if mobile TV is not to get a red card from consumers.
Mobile TV is increasingly spoken of as the next vital application for the cell phone industry, struggling to diversify revenues from sources other than voice and text messages.
Most operators plan to stream games over their 3G networks onto phones, ensuring that it cannot be a mass market service. Streaming, as opposed to broadcasts, can be slow and can jam networks if too many users try to download signals at once.
Broadband developments such as this continue to highlight the challenges which face wireless broadband operators, and in particular, the operators and equipment vendors that have bet the farm on WiMAX. The question is: how can WiMAX compete with fixed broadband when WiMAX equipment costs are an order of magnitude higher but the supported bandwidth is almost an order of magnitude lower? If anyone knows the answer, they should hurry and tell Charles Dunstone before he forks out a wad of cash for AOL UK.
A few months ago I had two pieces of junk-mail drop through my letter box from two broadband providers serving the London area – Bulldog, a DSL provider, and Now, which offers wireless broadband using the UMTS-TDD standard. The Bulldog flyer was offering me 8Mbps broadband for £19.50 a month, while Now was offering 512Kbps for £14 a month. Effectively, Bulldog was offering me a product 16 times as fast for just £5.50 more a month. To place this cost differential in perspective, £5.50 is the cost of a standard return journey on the London Underground, or the cost of a latte and hot Panini at Starbucks.
Whether it's paying for an item in a retail store, at a vending machine, a toll booth, or just doing the monthly utility bills, nothing happens in any of my accounts until I say "OK" securely from my little mobile companion device. It has "pins" and codes to verify who I am, and it is the only device authorized to approve transactions against my accounts. No "tickee" from it, no laundry.
With Ollila (r) credited as being the man that turned Nokia around from a sprawling, wellie boot-selling conglomerate to the world's biggest handset provider, Kallasvuo (l) has a hard act to follow. Kallasvuo will have the support of his predecessor as he takes over though. Ollila will remain as Nokia's chairman of the board, working a couple of days per week.
Kallasvuo takes the reins at a crucial point in the company's history. The N-Series of multimedia phones is winning plaudits; Nokia's decision to get involved with dual mode (VoIP and mobile) devices looks to be a wise one; and the recent debut of the 770 (l) - a mini-tablet computer with no cellular connectivity, running on Linux - is an interesting departure for the company, getting the blood of gadget freaks pumping.
Also, the converged device market, which combines cellular and non-cellular technologies such as wireless land is attracting a lot more interest. But those semiconductor companies that have not historically participated in the cellular space. We are in an excellent position to enable those companies with a complete cellular-base span solution which they can, then, integrate with their wireless land offering. Based on these and other positive market dynamics, we are hopeful that we can sign a number of modem agreements this year.
The third market challenge is supplying ASIC and software directly to suppliers of advanced terminal unit products. While somewhat further out on our road map, this channel would represent an excellent synergy between our advanced technology development efforts while we are driving higher value through price, power and performance advantages, and those manufacturers that produce lower volume, data oriented products that require the most advanced data rate oriented solutions.
ARLINGTON HEIGHTS., Ill., June 8 /PRNewswire-FirstCall/ -- Following its recent announcement of the world's first nationwide 802.16e WiMAX network in Pakistan, Motorola, Inc. (NYSE: MOT - News) today continues its aggressive leadership in WiMAX technology with plans to develop a comprehensive ecosystem for personal broadband "on the go."
"It was a long and sometimes difficult road, but the industry ultimately came together and reached its goal,” said (InterDigital's) Brian Kiernan (l), Chair of the IEEE 802.16e Task Group. "The IEEE 802.16e standard gives service operators the ability to provide a wide range of new and revolutionary high-speed, mobile wireless applications and services that will greatly improve people’s way of life.”
"The WiMAX Forum commends IEEE 802.16 for its exceptional work in delivering a global standard that will redefine mobile broadband," said Ron Resnick, president of the WiMAX Forum. "Today marks the official inauguration of the IEEE 802.16e standard, and the WiMAX Forum and its members now can move forward with confidence as we collaborate to ensure that WiMAX Forum Certified products for 802.16e-based mobile broadband arrive by late next year or early 2007. As an organization, we have already achieved accelerated progress by developing system profiles based on the 802.16e specification and identifying conformance test tools and methods that will be essential for the expanding the certification process to include mobile as well as fixed systems."
The IEEE has more than 375,000 members in approximately 150 countries. Through its members, the organization is a leading authority on areas ranging from aerospace, computers and telecommunications to biomedicine, electric power and consumer electronics. The IEEE produces nearly 30 percent of the world's literature in the electrical and electronics engineering, computing and control technology fields. This nonprofit organization also sponsors or cosponsors more than 300 technical conferences each year. Additional information about the IEEE can be found at http://www.ieee.org.
Speaking recently, the Marketing Manager, Netcom Africa, Mrs. Lolade Shonubi, said that when the company compared speed, mobility, activation, security and maturity of available technologies, UMTS TDD was found to be the best option for mobile broad band. She said further that many of the biggest trends in telecommunications and technology point to the need for a ubiquitous, very high speed, low latency, packet based platform to provide broad band and other packet services to users at home, work, or on the road. "The first real world proven platform that meets this need is the UMTS TDD (also known as TD-CDMA) which is the TDD variant of the 3G UMTS standard", she noted. UMTS TDD, Shonubi said is a commercially proven technology, debugged, working smoothly, with excellent spectral efficiency, sensible economics. She said the facility has proven its ability to compete with DSL as a broad band service with hand-off and roaming.
The handset's main display is a 2.5-inch and beautiful wide-view LCD screen. Approximately 3 hours of continuous digital TV viewing is possible. The P901iTV allows users to enjoy services that blend mobile communications and broadcastings. For instance, when you are watching the TV program, you can go to websites related to its TV program simply by clicking the URL shown on the display during the broadcasting.
Hidden beneath the gibberish alphabet soup that is HSDPA lies an upgrade which requires both mobile network operators and end users to exchange their current equipment - base stations and handsets, in other words. The technology itself is an upgrade to existing UMTS 3G networks - not unlike what EDGE represents to GPRS, and raises the theoretical 384 Kbps limit of current 3G data transfer to a whopping 1.8 Mbps, which translates to download speeds in the range of one megabyte every three to four seconds.
Apart from the increase in speed, HSDPA does not offer any other advantages as compared to current 3G phones, which calls for a certain amount of sober consideration of your actual needs. A business user who frequently downloads large attachments is likely to benefit from owning such a handset, but will need to connect his or her phone to a laptop via USB as the built-in modem capabilities of Bluetooth cannot handle the data rates of HSDPA.
it becomes a zero-sum gain. other than the fact that the whole industry is growing like crazy. idcc should eventually be able to license the vast majority of the units. some earlier, some later. meanwhile, IDCC is instrumental in the very standards bodies i mentioned. 802.11k, 802.16c/e, 802.21, LTE, hsdpa, hsupa, MIH, heterogeneous switching, (homogeneous switching for that matter), mesh networks, OFDM, WiMax, etc..
Someone is a lot stronger than Infineon (IFX) in China if they only have 5% market share!
South Korea's two iconic mobile technologies will merge this year _ the code division multiple access (CDMA) for mobile telephony will combine with portable Internet-enabling WiBro.
OFDM-MIMO: Key to greater performance
OFDM is a logical next step in broadband radio evolution. It is already being applied in IEEE standards like IEEE 802.11 and 802.16, also referred to as Wi-Fi and WiMAX, respectively. Standards groups are currently working to standardize OFDM-MIMO as it relates to Wi-Fi and WiMAX. At this time, OFDM-MIMO is not part of the formal evolution path for existing cellular systems based on the 3GPP (UMTS, HSDPA) and 3GPP2 (CDMA 1X, EV-DO) standards; however, standards groups are working to understand its role in providing wireless broadband.
Release 6 of the FDD standard introduces HSUPA. HSUPA increases the uplink rate to a theoretical maximum of 5.8 Mbps. Release 6, which includes both HSDPA and HSUPA, is poised to support high speed data in both the uplink and downlink, reduce the latency in data transmission, and increase overall network capacity. In addition to HSUPA, Release 6 adds MBMS (Multimedia Broadcast Multicast Service) functionality which is a means to provide subscription and non-subscription based broadcast services in 3G cellular networks. Our current efforts include upgrading our Release 5 technology to Release 6, phasing the additional features into product offerings according to projected market acceptance.
Recognizing the need to continue to improve data rates, coverage and capacity, work is underway within 3GPP on further evolution of the standards. Release 7 is expected to address incremental performance improvements. In addition, a longer term initiative known as Evolved UTRA/UTRAN (UMTS Terrestrial Radio Access/ UMTS Terrestrial Radio Access Network) is underway. The objectives of this initiative are more ambitious, targeting peak data rates of 100 Mbps in the downlink and 50 Mbps in the uplink, improved spectrum efficiency, significantly reduced data latency, and scaleable bandwidths from as low as 1.25 MHz to as high as 15 MHz. We are participating in Release 7 and evolved UTRA/UTRAN standards activities and have launched internal projects to develop the technology necessary for the new performance requirements.
mschere found that some Cognio patent numbers were showing up on the IDCC patent page...I don't think the company actually came out and stated Cognio though
Over last couple of years, Flarion's Flash OFDM technology, has demonstrated the promise of OFDM for next-gen 4G cellular networks. Qualcomm understands the growing popularity of OFDM as a technology for next-gen networks including standards like WiFi, .11n, WiMAX, 802.20, 3GPP LTE, etc.
It is against this backdrop that operators within ETSI have accelerated discussions on IPR so that agreement is reached before an LTE workplan is created by 3GPP and are prepared to delay finalisation of standards until IPR is solved.

Ten years ago, who would have imagined a hard drive in a cellular handset? But as the mobile phone becomes a multimedia entertainment and computing device, it has incorporated high-capacity storage similar to that of a PC. Samsung's SPH-V5400 was one of the first handsets to include hard drive technology, offering 1.5 GB of storage back in 2004; since then we have seen Nokia's N91 with 4 GB, and most recently Samsung's SGH-i310 with 8 GB. "As the cellular handset becomes the one device that the world carries, the standalone MP3 player may well be left behind," says Alan Varghese, ABI Research's principal analyst of wireless semiconductor research. "What's important to many users is having one device that handles mobile music as well as the other functions--phone calls, digital photography, email, web browsing--now performed by mobile phones.
