HSDPA Code Tree

How often does it happen that people ask you questions you know the answer to but cant recall the complete details. A similar thing happened when a colleague asked me about why only 15 codes why HS-PDSCH and what happens to the 16th code.

Here is a picture which is from Qualcomm Whitepaper (available here) which is self explanatory.

August 2009: Mobile TV Roundup

Qualcomm is slowly building content for its Flo TV mobile service for cell phones with the recent announcement that Discovery Communications launched a Shark Week Mobile Channel.
Discovery Channel’s Shark Week programs are scheduled to air on the Flo TV service through Aug. 14.

Flo TV uses the analog spectrum previously occupied by television broadcasters, and offers programming from several of the large network brands. Flo TV President Bill Stone says he envisions expanding the service from cell phones to cars and other consumer electronics products.

Flo TV, however, is not the only mobile TV service. AT&T CruiseCast launched a satellite-based television service in cars June 1.

CruiseCast, which is really an AT&T logo slapped onto RaySat Broadcasting equipment and services, offers 22 TV channels and 20 satellite radio channels. Its satellite antenna is a fat disc the size of a Bundt cake affixed to the roof of a vehicle.

The service costs $28 a month, plus $1,300 for equipment, which requires certified installers who charge an additional $200-$300, says Jim Llewellyn, who demonstrated the service July 31 in San Diego.


If you feell you're missing out on The Ashes action, you can now watch the Ashes for free on your W995.

A 3-month pass for the Sky Mobile TV service now comes bundled with the device exclusively on the 3 Network.

With the service, you can watch eight made-for-mobile channels that use highlights content from the Sky Sports 1, 2, 3 and Xtra channels. You’ll also be able to watch live matches right on your W995 too.

Australian cricketers Glenn McGrath and Matthew Hoggard appeared at the launch of the new bundle, and McGrath expressed his thoughts on the new bundle, saying ”the Sony Ericsson W995 on 3 is a real must for any dedicated cricket fan. To be able to access crucial games via Sky Mobile TV on the go, especially when a tournament like The Ashes is on is invaluable to me.”

After the initial 3-month period, Sky Mobile TV will cost you £5 a month. So, while the savings aren’t amazing, amounting to a whopping £15 in total, it’s still a great feature to have right now if you’re a cricket fan.

Testing of free mobile digital TV for cell phones, netbooks and other on-the-go devices is ramping up in the weeks ahead, and the first devices that can provide such broadcasts should be on store shelves by next year, according to the broadcaster-based group behind the effort.

"Just like you turn on your TV today at home and watch live and local broadcast television, you will turn on your handset and be able to watch live and local broadcast television," said Anne Schelle, executive director of the Open Mobile Video Coalition.

Trials are underway around the country in cities such as Chicago, New York and Raleigh, N.C. The biggest test pond will be Washington, D.C., where broadcasters have the attention of what may be the nation's most powerful audience — politicians. "We already have two stations on the air there, and we'll have the rest of our stations on air by next week," said Schelle.

Cell phones are probably the largest single group of devices that could receive local TV programming.

"There are 250 million of them out there," said Schelle. It's not clear whether wireless carriers are as enthusiastic.

MobileCrunch has picked up an interesting story from AV Watch - who themselves have spotted a USB tuner that plugs in to your TV, and then streams out 1-Seg (that’s a Japanese TV standard) formatted TV that your iPhone/iPod Touch can pick up via an App running over WiFi. Nice.

The iPhone has been at somewhat of a disadvantage for a time, because unlike a lot of other phones in Japan, it can’t natively pick up a TV signal - Japan is one of the places where Mobile TV has worked (but there are a number of specific reasons for that….), so this little bit of kit solves an issue for people who need their TV fix.

The USB device is called the SEG Clip, and is sold by I-O data it follows a previous device that was more of a standalone unit from Softbank Mobile - that one was it’s own receiver, transmitted the data by WiFi, but also double as an extra battery if you plugged it in to an iPhone.

WISH-TV today announced the expansion of its mobile offerings to include a new application for BlackBerry smartphones. This mobile application is the latest addition to 24-Hour News 8’s fully synchronized television and digital offerings that are available free of charge at www.wishtv.com .

WISH-TV unveiled its iPhone custom application with great popularity and much success in May 2009. In addition to these specialized applications, 24-Hour News 8 is also available via any web-enabled mobile device.

LIN TV , WISH-TV’s parent company, in conjunction with News Over Wireless (NOW) has developed the custom BlackBerry smartphone and iPhone applications for each of its 27 local television stations. Six LIN TV stations, including WISH-TV, launch the BlackBerry smartphone service today. LIN TV is the first in its local markets to provide instantaneous and on-demand access to its local news, sports and entertainment, as well as video, weather forecasts and traffic reports to BlackBerry smartphone subscribers.

Six LIN TV stations launched the BlackBerry service last week, including WISH-TV, WAVY-TV, KRQE-TV, WANE-TV, WALA-TV and KXAN-TV. LIN has been among the more aggressive broadcasters in the deployment of its content over nontraditional platforms.

Media Content and Communications Services (MCCS) has made its Hindi, Marathi and Bengali news channels -- STAR News, STAR Majha and STAR Ananda -- available on the mobile TV platform.

The content of all three channels will be streamed live, including the ads that appear during the news programmes. The content will be available on the 3G networks of MTNL and BSNL. However, the company claims that their mobile TV option will also be made accessible to subscribers of other telecom operators, who offer 2.5G services.

Currently, only two mobile operators -- BSNL and MTNL -- offer 3G services in India. The video content delivery process is faster on 3G mobile networks, as compared to 2.5G.

Qualcomm to put Femtocells in Mutant Animals ;)

In the latest breakthrough from its labs, Qualcomm has perfected a new version of its system-on-a-chip (SoC) technology that can be embedded into animals, turning them into living, breathing highly mobile femtocells. By creating biological femtocells, Qualcomm is allaying one of the critical weaknesses of the wireless network: while the devices on the network are mobile, the infrastructure of the network is static. By turning the family dog, for example, into a femtocell, the issues of dead zones and coverage gaps disappear as coverage moves with you wherever you—and your dog—go.

Research into these dynamic biological networks is still in its infancy, but Qualcomm has released a demo video on the technology, which you can view below. As part of that research, Qualcomm is trying to overcome what it sees as the inherent limitations of many species of animals. Pigeons, for instance, could be used to create a pervasive flying network in any heavily trafficked downtown area, but the pigeon isn’t the most long-lived of animals and it has several predators, thus requiring an operator to constantly reintroduce new pigeons into the network to maintain capacity levels.

Qualcomm has solved that problem through genetic engineering. It has crossbred a pigeon with a wolf, creating a hardier more aggressive femtocell that can defend itself from both predators and the elements. The only problem with this approach, though, is its high susceptibility to industrial espionage. A rival operator could introduce biological femtocell predators into a market, to attack, maim and possible even eat another operator’s femtocells. While bio-engineering femtocells such as the wolf-pigeon might seem a natural defense mechanism against tactics, the rival operator could always engineer a better femtocell. Qualcomm demonstrated how a shark crossbred with a hawk could effectively nullify a femtocell networks composed of wolf pigeons.

By the way, I hope you have realised that it was an April Fools joke :)

HSPA+ to become more widely available in 2009

According to 3G Americas press release, 100 million new connections were added last year. On a worldwide basis, GSM totals 3.5 billion of the nearly 4 billion mobile subscriptions or 89% share of market at the end of December 2008. With 278 UMTS-HSPA networks in service in 121 countries, there are 290 million UMTS-HSPA subscriptions as of the end of 2008 compared to 186 million a year earlier—more than 100 million new 3G connections. UMTS-HSPA subscriptions are expected to more than double in 2009, according to Informa’s forecasts, and reach 455 million connections by the end of this year.

A survey last year by GSA showed that over 1000 HSPA devices have already been launched. Remember HSPA device could be HSDPA device only or HSDPA and HSUPA device. According to Dell'Oro group, Worldwide total mobile infrastructure market revenues grew 5% in 2008, driven by the nearly doubling and quadrupling of revenues of the WCDMA and WiMAX markets, respectively.

The focus is now moving towards HSPA+ (Release 7). HSPA+ is already becoming everyones favourite as it now has the potential to compete with LTE. The HSPA+ data rates will soon be able to rival that of LTE. No new spectrum will be required and enhancements will now allow multiple bands to be used at the same time thereby reducing the need to move to LTE for gaining higher data rates by use of higher bandwidth.

O2 Germany is planning to upgrade its network to HSPA+ by mid 2009. Vodafone also plans to upgrade its network to HSPA+ when more devices are available. Hong Kong operator CSLNWM is working with China's ZTE to upgrade their network to SDR based HSPA+ network that could easily be upgraded to LTE. Australia's Telstra has already announced at the Mobile World Congress in Barcelona that it is the first in the world to offer mobile broadband service with peak rates of 21 Mbps made possible through HSPA+ technology.

On the devices front Huawei has E182E HSPA+ slide USB stick supporting 21.6Mbps DL and 5.76Mbps in UL. Novatel surprisingly has the same specs for its MC996D modem. Qualcomm meanwhile has released a range of new HSPA+ capable chipsets. The MSM8260 supports 3GPP Release 7 HSPA+ for data rates of up to 28 Mbps. The MSM8660 adds support for 3GPP/3GPP2 multimode, and the MSM8270 adds support for Release 8 dual-carrier HSPA+ for even higher data rates of up to 42 Mbps. All three products offer full backward compatibility to previous generation networks and are pin-, software- and functionally-compatible.

Its just a matter of time before we will all be able to experience the HSPA+ speeds on our mobiles and mobile connected Laptops.

UMB now officially dead, Long live LTE!

As one article put it, "Qualcomm cancels its own 4G system" going further to mention "Ultramobile broadband (UMB) is ultra dead". I blogged earlier about Nortel abandoning its CDMA business and about CDMA operators defecting to LTE and was sort of waiting for this imminent announcement to happen. There were already rumors about this happening since last year. (Not sure if some Hedge fund managers did be on this ;). UMB is also known as CDMA2000 EV-DO Rev C.

Qualcomm Inc officially announced that it has stopped development of Ultra Mobile Broadband (UMB), its next-generation, high-speed wireless technology, and has been making small-scale layoffs as it looks to cut costs in the weakening economy, Chief Executive Paul Jacobs said. Jacobs said the company was putting resources into LTE technology instead.

The company that created CDMA techology, meant for UMB to be CDMA’s 4G play. The company had high hopes for squeezing out WiMAX, positioning UMB to compete directly against LTE. With a logical upgrade path for existing CDMA carriers, UMB was designed to continue the GSM vs CDMA platform war in the fourth generation of wireless technology.

However, Qualcomm in recent years has gained dominance in the LTE development field as well. With Qualcomm now heavily invested in UMTS/HSPA technology, UMB had Qualcomm playing both sides, ensuring that they would be dominant in all CDMA-derived products (both UMB and LTE use technology originally derived from Qualcomm’s oldest CDMA patents).

With WiMAX becoming embraced, and even deployed, globally, UMB failed to gain a single carrier. The main cause for CDMA carriers defecting to WiMAX, has been Qualcomm’s monopoly on the technology. WiMAX trumps UMB in being an industry standard, not controlled or mandated by a single company.

The CDMA Development Group (CDG) has yet to comment on this announcement. However, the CDG has told PhoneNews.com that their driving force going forward will be to foster CDMA as a low-cost network option, especially in developing nations. Qualcomm still hopes to use CDMA for new networks in Africa, using their own hybrid GSM/UMTS/CDMA chipsets for international roaming when those customers travel abroad.

This leaves LTE as the eventual winner and with Operators already planning to roll out LTE network mid next year, WiMAX is going to get tough competetion from LTE. CDMA2000 operators meanwhile will have to now start planning how to move towards LTE (or WiMAX for that matter). 3GPP has laid down clear evolution path to move to LTE from CDMA2000. Other option which I quoted earlier is the eHRPD approach.

Qualcomm to make Femto-Intelligent Handsets

The last time I read about Qualcomm bying stake in Femtocell maker Ip.Access, I overlooked it but now the rumors are that they want to be the leaders in Femto-Intelligent handsets. This fits well with Femto-optimised handsets plan that I blogged about.

Ovum had interesting analysis on the original news:

It's easy to see, though, how femtocells fit into Qualcomm's vision of the future of the wireless world. It's not too much of an exaggeration to say the company believes that the WCDMA radio technology is so good that no other is needed; curiously, ip.access's other industry investors, including Cisco and Motorola, are much more closely associated with the opposite position. Some years ago Qualcomm engaged in a sustained rubbishing of WiFi as a public access technology, and more recently it has given WiMAX the same treatment. Femtocells could be a route towards using WCDMA in home and other internal networking.

The reality may be more prosaic. According to Qualcomm Ventures' self-description, its “aim is to support Qualcomm's mission of enabling and fostering 3G (WCDMA) and wireless Internet markets through strategic investments in privately owned startup ventures.” With femtocells at least a plausible runner in the medium term in the future development of public mobile networks, not investing anywhere in the technology might almost be deemed remiss. In Qualcomm's own words, both it and ip.access “have developed key intellectual property for femtocells, share the same vision for femtocells, and can work together to make the most effective use of these ideas for the benefit of the whole femtocell industry.”

From ip.access's perspective, the deal is somewhat more straightforward. It believes that Qualcomm is buying in because of its technological excellence and 'traction' with operators - it claims involvement in a number of femtocell trials with major MNOs, though none of these has been publicly disclosed.

For ip.access, the money Qualcomm is bringing is less interesting than the relationships and influence - especially with standards organisations - that it adds. Privately held, the company already lists Cisco, Intel Capital, ADC and Motorola Ventures among its owners. Neither party is disclosing the extent of Qualcomm's investment, or whether it will have any significant impact on the balance of shareholdings.

We are still mildly sceptical about the femtocell business case; even though ip.access provides some interesting data on the impact that domestic femtocells can have on the capacity requirements for the macro network. But it's clear that Qualcomm's decision to buy into ip.access makes the proposition rather more credible.

Qualcomm to back MediaFLO at the expense of MBMS

Just couple of days back I was complaining about everyone abandoning MBMS but now I can see why Qualcomm is suddenly uninterested in MBMS:

U.S. mobile technology company Qualcomm Inc. (QCOM) said Friday that it acquired an L-band radio spectrum licence for GBP8.3 million that will enable it to bring new mobile TV and wireless services to the U.K.

Qualcomm U.K. Spectrum Ltd bought the licence to use 40 Megahertz of the 1452 MHz to 1492 MHz band in an auction by communications regulator Ofcom.

The licence is suitable for offering mobile television, wireless broadband and satellite radio, Ofcom said.

The L-Band spectrum license acquired by Qualcomm covers the entire United Kingdom and is technology neutral, thereby enabling Qualcomm to use the spectrum for innovative technologies, depending on its assessment of market needs in the United Kingdom.

The L-band, on which any technology or service can be used, will contend with two main rivals, DVB-H, backed by Nokia, the handset maker, and by Viviane Reding, the European Telecoms Commissioner, who wants to make it the European standard, and TDTV, which is being tested by Orange and T-Mobile in the UK. All three technologies would require special handsets able to pick up a broadcast signal.

Mobile companies including Vodafone and 3 already offer mobile television in Britain, but take-up has been poor.

Qualcomm said that it does not intend to run a mobile TV broadcasting network as an operator, as it has done in the United States, but is looking for partners to launch its mobile television technology, MediaFLO.

Andrew Gilbert, head of Qualcomm's European operations, said: “We will not attempt to become an operator, but if service providers want to partner with us ... we are open to talking to folk.” Mr Gilbert added that Qualcomm would use the spectrum to bring a variety of wireless technologies to the UK market but that it had no timetable for launches in mind.

With industry heavyweights supporting DVB-H and TDTV, analysts see this as Qualcomm's last chance to bring MediaFLO to the UK and European markets. Will Harris, of Enders Analysis, said: “One potential outcome from this is that two competing mobile TV services could be launched. While it is too early to say which technology will win at this stage, those that fail to get support from the mobile operators will lose.”

O2, the mobile network provider, was initially interested in the L-band auction, but pulled out without bidding. Failed bidders include WorldSpace, the satellite radio group, and The Joint Radio Company, which runs spectrum for the UK energy industry.

The next competition, to run later this year, is even more significant. It has a price tag that could run into the tens of millions because it is for a frequency that supports WiMax, a high-speed network technology similar to a common WiFi home wireless system, but with a more robust signal and a range of a kilometre or more.

Although WiMax is not new it has had little success so far. But interest is hotting up. In the US last week, Sprint Nextel announced a $14.5bn (£7.4bn) joint venture with Clearwire to build a network servicing as many as 140 million people by the end of 2010. And Google is pumping another $500m into the scheme.

At the moment, the UK market is small. Freedom4 and UK Broadband, a subsidiary of PCCW, are the only providers with a national licence, and only limited services are available. But developments on the other side of the Atlantic are fuelling interest, and some big players are lining up for the relevant spectrum auction. Ian Livingston, who takes over aschief executive at BT in two weeks' time, has said thecompany is interested, and Vodafone has trials running in Malta.

Freedom4 is also already in talks with potential investors about the £100m infrastructure funding it estimates it will need from 2009-11. "We are talkingto our partners and the banks," Mike Read, chief executive of Freedom4, said. "Following the deals in the US, there is moreinterest in what we are doing over here."

Ian Keene, a senior analyst at Gartner, said: "There is abusiness case for WiMax in the UK, but most likely it will becity-centric and focused on business, rather than nationalcoverage competing with mobile networks."

The biggest auction of all will be next year's bidding for the "digital dividend" – the wide bands of frequency freed up when the analogue television signal is switched off in 2012. The debate about who should get what is already well under way. Broadcasters claim a substantial portion for high-definition TV, mobile operators want it for next-generation cellular services such as video, and internet service providers say it iscrucial for the broadbandinfrastructure.

Qualcomm and Healthcare

Qualcomm is diversifying its portfolio by starting a MVNO focussed on healthcare. An article that appeared on Wireless Week has some interesting information on this.

Qualcomm is preparing to launch a standalone mobile virtual network operator (MVNO) company focused on healthcare, although designed to have a broad consumer appeal.

The new company, which was incorporated recently under the name LifeComm, was created by Qualcomm and several other, unnamed, partners. Don Jones, who is vice president of business development for QUALCOMM's' health and life sciences unit, says the MVNO likely will launch commercially sometime in the second half of 2008.

Although the MVNO will have a healthcare focus, Jones says it plans to have applications and services designed to help consumers maintain their personal health as well as more specialized medical uses.
"We don't see it as just health care," he says, because the MVNO also will offer services for wellness, fitness, and health maintenance.

The specific applications and services the MVNO will offer have not been determined, but Jones says the company wants to establish a brand known to provide services for anyone interested in his or her health. The target audience, he says, is predominantly going to be women ages 40 to 65 because they are "influencers" when it comes to health.

Services could involve fitness, weight management or reduction, diabetes management, and monitoring heart health, including hypertension and congestive heart disease.

LifeComm already is talking to handset manufacturers about designing phones with consumer appeal but with the capability of linking to the MVNO's special applications and services, Jones says. One of the plans is to have handsets that would create a personal area network that could communicate with medical devices such as heart and blood pressure monitors. They also could connect to consumer devices like pedometers. Some of Qualcomm's partners in the MVNO are medical device manufacturers.

Jones also talks about using innovative devices like "wireless Band-Aids," which stick to the skin and monitor some bodily functions. Such devices are in use now for mobile health care, as well as wireless pacemakers, remote electrocardiograms and wireless blood glucose meters.

LifeComm expects to close on a bridge loan in the next few weeks to provide initial funding as a separate company. Jones says the company will then start pulling together an executive team and will do additional market research.

LifeComm has an agreement with a CDMA wireless carrier to provide network services for the MVNO, although Jones says he cannot announce which carrier. He did say the MVNO expects to use Qualcomm's BREW platform, which is the platform used by Verizon Wireless. The MVNO also will use assisted-GPS for location services.

This isn't the first time that Qualcomm has spun off a separate company to take advantage of technology it has developed. The latest example was MediaFLO USA , which is building a nationwide network for mobile broadcast TV services.
