326 Million Dual-Mode 4G Devices to be Activated by 2016

MARAVEDIS RESEARCH :

MONTREAL, Canada, May 31, 2011 - 326 Million Dual-Mode (3G + LTE) Devices will be Activated by 2016 according to Maravedis' latest research titled "Global 4G Device Forecast 2011-2016". "All LTE devices activated during 2010, including USB data cards, modems and notebooks, were single-mode," said Cintia Garza, author of the report. "However, LTE+3G smartphones have emerged during 2011 as more LTE operators begin to add LTE to their device offering, in particular smart phones whose adoption will be key to LTE uptake." In the United States, Sprint's early success with WiMAX smart phones suggests a very promising uptake for LTE smart phones.

Many other carriers around the world are also looking at introducing smart phones in their LTE device portfolio by the end of 2011, such as NTT DoCoMo (Japan), and Yota (Russia). "By 2013, more than 50% of LTE devices activated worldwide will support both FDD and TDD duplex modes, once TD-LTE deployments consolidate in China, India, Malaysia, Korea and other APAC countries," continued Garza. "On the other hand, 75% of the LTE devices will support legacy systems (2G/3G) and 9% will support WiMAX technology; these devices will mainly include smart phones, tablets and USB dongles".

Tablets are also one of the most promising devices in the 4G device market. Maravedis' report predicts tablet shipments will grow from 46 million in 2011 to nearly 150 million by 2016. Apple iOS is expected to remain the most popular tablet for the coming years, reaching 46% market share by 2016.

Additional Research Findings:

260 million dual-mode (TD LTE + FDD LTE) devices will be activated by 2016Android will account for 48.5% of the smart phone market, Windows 21% and iPhone (iOS) 16.5% by 2016.

APAC and Europe will account for the largest number of smart phones and tablets activated by 2016.

By 2016, 95% of the tablet installed base will be 3G/4G enabled.

AT&T bringing LTE to five cities this summer

AT&T announced last fall that it would begin its LTE rollout in mid-2011, and it's now finally delivered a few more details. The carrier has just confirmed that five markets -- Dallas, Houston, Chicago, Atlanta and San Antonio -- will be getting LTE sometime "this summer," with ten more as-yet-unnamed cities set to join them in the second half of the year.

All told, AT&T says that should cover about 70 million Americans by year's end. Of course, an LTE network needs some devices, but AT&T unfortunately isn't providing much in the way of details about those just yet -- it's only saying that it plans to add 20 4G devices to its portfolio this year, and that "some of those" will be LTE capable.

Press Release

By John Donovan, AT&T Chief Technology Officer

AT&T has delivered five mobile broadband speed upgrades in recent years, including our HSPA+ deployment last year. And average nationwide speeds on the AT&T network have increased – more than 40 percent over the past two years alone.The next network evolution will arrive this summer with the addition of LTE in five markets – Dallas, Houston, Chicago, Atlanta and San Antonio. We plan to add another 10 or more markets in the second half of the year, and cover 70 million Americans with LTE by year-end.

We also have plans to add 20 4G devices to our robust device portfolio this year, with some of those being LTE capable.We're positioning to deliver a great mobile broadband experience in the near term with HSPA+ and a growing LTE footprint.We've invested $75 billion in our wireless and wired networks over the last four years – more capital invested in the U.S. than any company in any industry.

And we plan to invest $19 billion in our wireless and wireline networks and other capital projects this year. The investments we've made to evolve our mobile broadband network in recent years, plus what we have planned for the future, put our customers in position to benefit fully from a host of coming mobile broadband innovations.

T-Mobile takes on LTE with HSPA+ 42 Mbps launch in 55 markets

May 24, 2011 — 12:01am ET By Mike Dano

T-Mobile USA announced it will launch HSPA+ 42 Mbps speeds in 55 markets across the United States, including Atlanta, Chicago, Denver, Detroit, Dallas, Houston, Los Angeles, Miami, New Orleans, Phoenix and elsewhere.

The launch essentially doubles the speeds provided by T-Mobile's current HSPA+ 21 Mbps network, though the carrier said it will continue to brand the offering as a 4G service.

T-Mobile announced at the Consumer Electronics Show in January that it would upgrade its HSPA network to HSPA+ 42 technology. At the time, the carrier said HSPA+ 42 will provide speeds comparable with Verizon Wireless' (NYSE:VZ) recently launched LTE network. T-Mobile said it tested T-Mobile's planned HSPA+ 42 upgrade against Verizon's LTE network in Las Vegas, and found both networks provided average download speeds of around 8 Mbps.

To support the HSPA+ 42 launch, T-Mobile said it will begin selling its first 42 Mbps-capable product, the T-Mobile Rocket 3.0 laptop stick, starting May 25. Built by ZTE, the stick will sell for $99.99 after a $50 mail-in rebate and with a qualifying mobile broadband plan (2 GB or higher) on a two year service agreement, with voice line and enrollment in Easy Pay. Customers can also purchase the T-Mobile Rocket 3.0 without a contract for $199.99.

Earlier this year, T-Mobile's CTO Neville Ray said the carrier expects to cover around 140 million POPs with HSPA+ 42 network technology by year-end.

AT&T Mobility (NYSE:T) announced in March its plans to acquire T-Mobile--an action that could scramble T-Mobile's network upgrade progress. AT&T has said if the deal goes through, it would work to move customers off of T-Mobile's UMTS service, which currently runs on its 1700 MHz AWS spectrum, and onto AT&T's 1900 MHz spectrum. AT&T will then run its LTE service over its 700 MHz spectrum and over AWS spectrum. In other words, T-Mobile customers with 3G handsets will eventually have to purchase new devices that work with AT&T's frequencies.

AT&T and T-Mobile expect the transaction to close sometime early next year.

LTE will boost capacity 230 percent over 3G according to British OfCom

4G technology will bring over three times more mobile broadband capacity to the UK from 2013, Ofcom said on Thursday.

According to research conducted by the telecoms regulator, LTE (long-term evolution) is 230 percent more spectrally efficient than HSPA, the 3G technology that currently provides cellular data connectivity to the country. However, LTE was not the only 4G technology considered in the research — Ofcom also looked at emerging and later generations of LTE's big rival, WiMax.

Stephen Unger, Ofcom's chief technology officer, said the efficiency of 4G spectrum use would increase even more by the end of the decade, by which point technologies such as the future LTE Advanced standard should be in place.

"4G mobile technologies will be able to send more information than 3G, for a given amount of spectrum," Unger said in a statement. "This increased efficiency means that 4G networks will be able to support increased data rates and more users.

"The research that we commissioned indicates that early 4G mobile networks with standard configurations will be 3.3 times (230 percent) more spectrally efficient than today's standard 3G networks," Unger continued. "To put this in context, a user on an early 4G network will be able to download a video in around a third of the time it takes today on a 3G network. It is anticipated that this efficiency will increase to approximately 5.5 times (450 percent) by 2020."

– Stephen Unger, Ofcom

Ofcom conducted the research to better inform its strategic spectrum management work. The 3.3-times boost is in comparison with the HSPA technology being used by 2011's handsets, although compared with "emerging, high-end 3G configurations" that use multiple antennas and more efficient modulation, 4G will only provide a 1.2-times spectral efficiency increase, Ofcom said.

The increased spectral efficiency of 4G will not in itself be enough to satisfy the growing thirst for mobile broadband, Ofcom added, noting that the upcoming auctions of the 800MHz and 2.6GHz bands will also be necessary to meet demand.

"Finally, mobile networks will also need to be designed intelligently to ensure the best use of spectrum," the regulator said. "In particular, the research anticipates a greater use of small cells to meet demand in specific areas."

Huawei Sues ZTE, So does Ericsson

Huawei sues ZTE for patent infringement in Europe

April 29, 2011 — 12:22pm ET By Paul Rasmussen

In a surprise move Huawei sued its fellow Chinese vendor ZTE in the European courts for patent and trademark infringement. Specifically, Huawei accused ZTE of flouting patents it holds relating to data cards and LTE technology.
According to Huawei, the company has started legal action in Germany, France and Hungary with the aim of stopping ZTE from using Huawei patents and trademarks. ZTE is charged with branding some of its data cards with the Huawei brand.
Song Liuping, Huawei's chief legal officer, was reported by the Financial Times as wanting to resolve the dispute through negotiations. However, suggestions to decide the matter out of court using cross-licensing had not provoked a substantive response.
ZTE's reaction to this move was surprise and puzzlement, but it also made plain that it rejected the allegations and threatened to instigate legal action itself. ZTE on Friday sued Huawei in China fore infrnging on patents it holds for LTE.
In a statement carried by the Financial Times, ZTE said: "ZTE Corporation is astonished that Huawei Technologies has taken these legal actions. As a company listed on the Hong Kong stock exchange, ZTE respects and adheres to international intellectual property laws and regulations without reservation, and absolutely rejects that there has been any patent and trademark infringement."
It also noted: "ZTE is always willing to negotiate on issues in good faith, but will definitely take vigorous legal action in situations like this to protect its interests and those of its customers worldwide."
However, a report carried by AFP said that Huawei had recently made public images of a ZTE-branded data card using a Huawei-registered trademark and patented design.
Earlier this month, Ericsson started legal procedures against ZTE in the UK, Germany and Italy over alleged infringement of patents for 2G and 3G technologies. Ericsson said that it spent four years attempting to resolve the issue with ZTE with no results.
