Mobile Digital TV in US coming soooon (Q1 2010)

In 2007, transmission of full-motion digital television signals to mobile and handheld devices was proven technically feasible. Leaders of the broadcasting industry came together to make mobile digital television a reality; they formed the Open Mobile Video Coalition (OMVC) to accelerate the development and rollout of mobile DTV products and services, maximizing the full potential of the digital television spectrum.

Today the OMVC truly represents the industry, with members that own and operate more than 800 commercial and public television stations nationwide.

There was a lot of publicity of MDTV at the CES 2010 recently in Lag Vegas, USA. Here are few Youtube clips on MDTV.

There is also an interesting OMVC Mobile TV Use Cases document available here.

Indian Mobile Users just keep increasing

From The Independent, UK:

India, the world's fastest-expanding mobile market, added more than 19 million cellular users last month to post the biggest monthly growth ever, according to official data Thursday.

India's number of mobile subscribers swelled by 19.10 million in December after climbing by 17.65 million the previous month, driven by some of the world's cheapest calling rates.

December's increase was a record for monthly wireless subscriber growth, according to figures from the Telecom Regulatory Authority of India (TRAI) posted on its website.

India's mobile phone companies added an average of nearly 15 million subscribers a month in 2009 to bring the total number of cellular users to 525.15 million - up 51.4 percent from December 2008.

The sector's explosive growth has drawn a flood of global entrants in the past few years, sparking a cut-throat billing war among the players which has hit revenues and profits.

The new players that have beaten a path to the country of nearly 1.2 billion people include Norway's Telenor, Japan's NTT DoCoMo, Britain's Vodafone and Russia's Sistema JSFC, hoping to boost revenues and make up for saturated domestic markets.

At least another four cellular company launches are expected in the first half of this year in India including Emirates Telecommunications Corp, or Etisalat, India's Datacom Solutions and Loop Telecom.

With the new users added in December, 45 out of every 100 people in India now have a mobile phone. Total teledensity including fixed-line users now stands at 48 percent of the population.

The Cellular Operators' Association of India forecasts the country's mobile phones will number one billion by 2013.

But industry leaders and analysts say the cellular market is getting too crowded and forecast a savage period of consolidation in which the number of players will get whittled down to around half a dozen from the 14 currently.

As mobile subscriptions surged, the number of fixed-line telephone subscribers continued to fall, edging down to 37.06 million at the end of December from 37.16 million a month earlier, according to the TRAI figures.

HSPA+ rollout updates, Jan 2010

It has been predicted that the growth of HSPA+ broadband across Europe is set to soar with the total number of subscribers set to nearly double across Europe in 2011.

A new report has predicted that by 2011 the growth of HSPA+ broadband across key European markets will soar, and could almost double compared to 2009. The number of subscribers is set to soar from twenty two million in 2009 to around forty three million in 2011. The report was released by CCS Insight.

According to the report HSPA+ broadband will be a major factor in seeing growth of one hundred percent in the to five major European markets. The report goes on to state that the European mobile broadband market will enjoy seeing both subscriber and revenue numbers double by 2011. Revenues are set to increase from around six billion Euros in 2009 to around eleven billion Euros in 2011.

Michael O’Hara, chief marketing officer at the GSMA, said: “It is clear from this report that with the right network investment, European mobile network operators will see significant growth in mobile broadband adoption in the next two years. HSPA technology will drive this rapid uptake across Europe as mobile operators and their customers continue to benefit from its expanding, vibrant and competitive ecosystem.”

HSPA+ was generally the most efficient way of upgrading use of bandwidth already in use and was likely to dominate in the short term at least, with an estimated 1.4 billion subscribers worldwide by 2013, around ten times the estimated take-up of LTE.

HSPA+ release 7, which became available last year, uses MIMO technology like that in 11n Wifi to help take the peak downlink throughput to 28Mbps, with 11Mbps on the uplink. Release 8, for which chipsets will become available this year, aggregates two carrier signals to bring peak data rates to 42Mbps on the downlink.

Release 9 will put two MIMO streams on each of two 5MHz carriers, aggregated to produce a 10MHz data pipe delivering 84Mbps on the downlink; the uplink uses simple aggregation to 23Mbps. A projected Release 10 would bring the peak downlink speed to 168Mbps, though this would require 20MHz carriers only available in the 2.5GHz and 2.6GHz bands.

Novatel Wireless, a developer of wireless data cards and other devices, said that it has added support for dual-carrier HSPA+ networks. The firm said it is using Qualcomm's MDM8220 chipset for the support, and will launch commercial devices in the second half of 2010 based on the chipset. Novatel said the new support will add more advanced data capability and other features to its offerings. Dual Carrier HSPA+ networks are expected to provide higher throughput to wireless data devices, and also helps address better service for cell phone users.

The new modem can receive data at up to 42M bps (bits per second) in compatible 3G networks. To increase the theoretical maximum download speed of the modem from 21M bps to 42M bps, Novatel uses two carrier frequencies instead of the usual one, a technique called dual-carrier. But it will only deliver the higher speed on networks that also support the technique.

Users can expect peak speeds at up to 30M bps, according to Hans Beijner, marketing manager for radio products at Ericsson.Leif-Olof Wallin, research vice president at Gartner, is a more pessimistic, saying increased traffic on the networks could negatively impact speeds. "I think it will be difficult to get above 20M bps," he said.

Sixty-six operators have said they plan to use HSPA Evolution, and so far 37 networks have been commercially launched, according to statistics from the Global Mobile Suppliers Association (GSA).

However, the version of HSPA Evolution that supports 42M bps is still very much in its infancy. Last week, mobile operator 3 Scandinavia announced plans to launch services when modems become available. In December, representatives from Vodafone and the Australian operator Telstra visited Ericsson to Stockholm to view a demonstration, but neither operator has so far announced plans to launch commercial services.

Ericsson and 3 Scandinavia have unveiled plans to roll-out a worlds-first 84Mbps HSPA+ wireless network. The initial rollout will cover Denmark and four Swedish cities. HSPA+ networks that currently operate in Canada, for example, offer speeds of up to 21Mbps depending on conditions. In the United States, T-Mobile recently announced a similar planned network.

Real-world tests of the 21Mbps networks show the services achieving around 7Mbps speed. If a similar performance could be applied to the new Ericsson/3 network, it could result in speeds of roughly 28Mbps at realistic distances and network load.

and 3 will also deploy 900MHz 3G networks in Sweden in a bid to boost coverage in remote areas, as existing higher frequency networks have left some users with poor performance.

The high-speed services will hit Denmark and areas of Sweden this winter if all goes to plan.

China Unicom is putting the finishing touch on the tests on its HSPA+ networks in Guangzhou, Shenzhen, and Zhuhai, which were kicked off in October 2009 by partnering with its three major suppliers Huawei Technologies, ZTE, and Ericsson.

HSPA+ is the next generation technology for China Unicom's WCDMA 3G service. HSPA+, also known as Evolved High-Speed Packet Access, is a wireless broadband standard defined in 3GPP release 7. The HSPA+ network claims with a transmission speed of 21Mbps, 1.5 times faster than its current 3G network.

The outdoor average speed of the networks built up by Ericsson and Huawei reach up to 16.5Mbps and 18.5Mbps on the downlink, 50% higher than that of the existing HSPA network. That means you can download a song within two or three seconds.

Cell C, South Africa, has signed a US$378m deal with the Chinese telecom equipment provider ZTE Corporation. Cell C would ever lead the industry as far as network infrastructure is concerned but it is a fact that Cell C will be the first South African operator to roll out HSPA+ technologies incorporating download speeds of up to 21Mbit/s – three times faster than anything currently available.

According to Cell C an important factor in the decision to appoint ZTE is its ability to offer 4G services using Cell C’s 900MHz frequency band which offers wider and deeper coverage than existing 2100 MHz networks, enabling cost effective deployment to rural as well as metropolitan areas.

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.

Mobile Phone Batteries: Past, Present and Future

Forty-five years ago, when, to most people at least, chips only ever came with fish, a man called Gordon Moore wrote a paper in which he said the number of transistors that could be squeezed on to an integrated circuit doubles about every two years. Three years later, Moore co-founded Intel, whose computer chips have, to this day, developed almost exactly at the dizzying pace he predicted. Today, an Intel microprocessor boasts more than a billion transistors packed so densely that you could fit two million of the things on the full-stop at the end of this sentence. What became known as Moore's Law has driven exponential growth in the digital revolution – the more transistors you can pack into a circuit, the faster and more powerful its chips can run while remaining cheap. But the batteries keeping those circuits pinging are not digital and still work according to basic principles developed more than 200 years ago.

In the 1780s, Italian physicist Luigi Galvani discovered that a dead frog's leg would spring to life when he applied two pieces of metal. Galvani had created a crude circuit and the phenomenon was taken up by his friend, the aristocrat professor, Alessandro Volta. His voltaic pile swapped frogs for brine-soaked paper and pieces of metal for a stack of alternating zinc and copper disks. Volta had created the world's first modern battery.

A battery remains, by its simplest definition, a device that turns stored chemical energy into electrical energy. A chemical reaction takes place within a series of cells with negative and positive electrodes separated by conductive electrolyte. When you hook up the battery, positively charged ions "swim" from the negative to the positive electrode, prompting negatively charged electrons to power the bulb of a torch or the screen of your iPhone. It's a chemical process and, up to a certain point, you can't shrink chemistry. Peter Bruce, a professor of chemistry at the University of St Andrews, says that while computer performance has effectively doubled every two years, the energy density in batteries has increased five times in about 100 years. "If you want to store more energy you really have to develop new materials and new concepts," he says. "It's not just making the same things smaller."

Bruce is among a host of scientists racing to get more out of the modern battery. He owes a debt not only to Volta but also to the man whose work in the 1970s gave us the modern rechargeable battery that powers nearly all our gadgets. Stan Whittingham, a British-born American chemist who studied at Oxford in the 1960s, was working at the research division of the oil giant, Exxon, when he realised that the excellent energy-storing properties of the element lithium made it an ideal material to be used in rechargeable batteries. "A lithium-ion battery holds about five times as much energy as a lead one," Whittingham says on the phone from Binghamton University in New York, where he's a professor of chemistry. "It got a lot of people excited because it was really a technology-changing idea. Without lithium-ion batteries, you wouldn't have your iPod or your mobile phone. They've given us so much but of course people want more and more."

Bruce is taking up that challenge with his "air-fuelled" rechargeable lithium battery. Put very simply, the Stair cell (St Andrews air cell) uses nothing more complicated than air as a reagent in a battery instead of costly chemicals. By freeing up space and exploiting one of the few elements that is free, Bruce's cells can squeeze more power into a smaller space at a reduced cost. "By using air in the cell we can get much higher energy storage up to a factor of 10," Bruce says. "That's exciting because it's difficult to improve the lithium ion battery beyond a factor of two."

A battery with 10 times the storage of the one powering your phone would see a return to the days of weekly phone charging. Meanwhile, other scientists are working to solve that other great problem of the modern battery – the time it takes to recharge. Gerbrand Ceder at the Massachusetts Institute of Technology (MIT) has been looking at improving the way the lithium ions themselves move through batteries – the faster they "swim", the more quickly they charge the battery. Ceder and his team manipulated the materials inside batteries to make the ions' passage smoother and watched as they travelled at incredible speeds. Ceder estimates that a prototype battery made using the process could be charged not in hours or even minutes but seconds. "If we could cut charging time from, say, two hours to one hour, you would probably still do it overnight," he says. "But if it's one minute, you would stand by and wait – it would be like filling your car or getting a cup of coffee."

Ceder has also worked with a team that has used genetically-engineered viruses to build the positively and negatively charged ends of a lithium-ion battery. The new batteries would be more flexible and efficient than existing technology but, like MIT's fast-charging battery and Bruce's Stair cell, they are very much on the laboratory drawing board.

It's a measure of both the greatness of the modern battery and the challenges faced by developers that, as Whittingham puts it (perhaps with a degree of pride): "For the next five years at least it's just lithium." In the meantime, manufacturers are racing to launch energy-efficient screens and hardware that place less demand on batteries. But with so much riding on the next big breakthrough, it's only a matter of time before we get batteries fit to power the next generation of gadgets and cars. For those of us increasingly shackled to our phone chargers, that time can't come soon enough.

LTE/EPS Security Starting point

Recently a colleague wanted to know from where should he start reading about LTE/SAE security. The obvious answer was 3GPP TS 33.401 which is the specification and provides complete details. It seems that some people get scared when they start looking at the specs and in that case it is preferable to have a book chapter or something similar that could provide useful information.

Agilent, the T&M manufacturers released a book last year on LTE and the chapter on the Security is freely available on the web which I have also stored on the 3G4G website. It is a good starting point and provides basic details that technically minded people may find useful.

You can have a look at the Security chapter here.

LG cementing its LTE handset leader position

LG has been in news recently for showing off their LTE preparedness:

LG Electronics MobileComm U.S.A., Inc. revealed at this year’s CES the advanced capabilities of Long Term Evolution or LTE technology. The company showcased LTE download speeds of 100MBps. Long Term Evolution is also known as the next generation mobile communication service technology.

LG conducted real-time demonstrations of video conferences, full HD video files and web-surfing at speeds up to 50Mbps for uploads and 100Mbps for downloads. All this was executed by connecting to the LTE USB Modem from LG. The offering gives extremely high data download speeds.

The company also unfurled to the CES attendees the ‘handover’ technology. This offering executes hindrance-free network conversion between LTE and CDMA networks. LG displayed endless data transmissions taking place between LTE and CDMA antennas which enables video file downloads, internet calling and web surfing. All this was done via the sleek version of the 4G LTE device which is an LG proprietary product fashioned for the Handover just last August.

LG has also teamed up with Verizon wireless to demonstrate the applications and capabilities that are possible with LTE networks. At the recently held event, the Verizon Wireless Innovation Center demonstrated many applications with Innovation Center member LG Mobile Phones being its main participant.

LG demonstrated LTE network and joined forces with other companies for formulating Home monitoring solutions, an indoor/outdoor IP security camera and a video conferencing product.

Alcatel-Lucent and LG Electronics have completed a successful handoff of an end-to-end data call between Long Term Evolution, or “LTE,” and CDMA mobile networks. The live, over-the-air handover consisted of an uninterrupted streaming video session conducted over Alcatel-Lucent's end-to-end commercial LTE and CDMA/EV-DO infrastructure using an LG Electronics CDMA and LTE dual mode device.

The handoff is compliant with the standards established by the Third Generation Partnership Project, or “3GPP.” According to Ken Wirth, president of 4G and LTE Networks at Alcatel-Lucent, since existing networks were designed primarily with voice in mind, the current explosion in data traffic is creating a challenge for service providers. The successful handoff demonstrates Alcatel-Lucent's readiness to deliver LTE to CDMA operators. LTE provides operators with the opportunity to deploy a system designed specifically to support data.

LG's M13 CDMA/LTE device incorporated for the testing is the world's first modem chipset for 4G LTE devices. It was created with commercial grade components and released in December 2008. The technology behind LG's M13 CDMA/LTE terminal is important in enabling LTE networks to operate transparently with existing CDMA networks.

According to In-kyung Kim, vice president of 4G development at LG Electronics Mobile Communications Company R&D Center, LG's M13 terminal will be an important device in enabling CDMA network operators to deploy a LTE network incrementally over a national CDMA network.

An article in Fierce Broadband Wireless summarises their leadership in these words:

LG has an impressive LTE track record: an LTE demo at Mobile World Congress 2008; the announcement of the world's first LTE chipset and modem prototype in November 2008; the first LTE-enabled mobile device Live Air Demo at Mobile World Congress 2009; the first FCC LTE Device certification built around LG's LTE chipset in June 2009; the first dual-mode LTE/eHRPD in-call handover in August 2009; and a 100 Mbps maximum throughput Live Demo at CES 2010.

3GPP Release8 June 2009 compliance, multiple band support (2.1 GHz Band1 or 700 MHz Band13), various system bandwidth, from 5 MHz to 20 MHz and max throughput with up to 100 Mbps downlink and 50 Mbps uplink, are among the main features supported by the dual-mode LTE/CDMA Vd13 device and LTE-only LD100U device.

In Las Vegas, LG executives recognized that the two devices recently unveiled are intended more to demonstrate their LTE development leadership and, likely, will not be launched as commercial devices. Although they didn't outline their exact plan, they disclosed that their own LTE modem will eventually be integrated into a netbook or notebook, meaning that a more integrated chipset solution will hit the market soon.

Known for its 2G and 3G handset line, LG relied on mature merchant chipset solutions such as Qualcomm, ST-Ericsson or Infineon chips, not LG technology. We can elaborate different scenarios to explain their new positioning as an LTE market driver. Gaining ground in all cellular technologies and capturing more than 10 percent of the total handset market as year-end 2009, leading them to third position worldwide, LG has decided to invest significantly into chipset development in order to become technology independent.

On top of the LTE modem, they will now introduce phones based on their own 2G/3G/4G intellectual properties to save cost and stay ahead. We could also speculate that LG wants to broaden their essential patents portfolio, driving 3GPP groups and initiatives to better compete with their current chip suppliers. In this case, once the LTE market matures and reaches a critical mass, LG will switch to third party players just as they have in the past. One more scenario has to be considered: following Nokia's early strategy, LG could license its LTE modem IP to partners that will manufacture the chipset solution and sell it back to them.

It's difficult to predict LG's long-term strategy in terms of chipset development at this point. The company has the scale to succeed, scale that small WiMAX players who recently announced parallel WiMAX/LTE roadmaps lack. In the new research report released by Maravedis in partnership with Reveal Wireless, entitled "WiMAX Wave2 Subscriber Station Chipset Vendors Competitive Analysis," we have identified the WiMAX chipset companies who have shifted to LTE by offering a flexible programmable base-band solution.

The LTE base-band chipset market is already crowded: incumbent manufacturers who ship in large volume (Qualcomm, ST-Ericsson, and Nokia), new entrants who traditionally relied on merchant solutions (LG and Samsung Electronics), and newcomers who leverage their OFDM expertise, WiMAX chipset background, and WiMAX ecosystem experience (Altair, Comsys, Sandbridge, Sequans and Wavesat) are committed to playing a significant role in the LTE baseband landscape. With Mediatek, Infineon, Marvell, and likely giant Intel poised to enter the market eventually, the field will soon be comparable to the aisles of CES 2010... very packed.

One thing I have learned is that initial leadership doesn't guarantee final outcome but we have to appreciate LG's rise in the LTE technology arena.
