    At today's Qualcomm QRD Summit in Shenzhen, China Mobile sent its Deputy General Manager of Products Wang Hengjiang to share some hardware stats. In 2012, over 60 million TD-SCDMA devices were sold, with December alone pumping out over seven million units. To put that into perspective, there are now over 220 million 3G phone users in China (as of end of November), meaning the carrier still has plenty of catching up to do as it had a late start in the 3G game. That said, Wang also announced that China Mobile aims to sell twice as many TD-SCDMA devices this year, with smartphones expected to take up over 80 percent of that segment -- hardly a challenge considering they already reached 94.4 percent in the last quarter. Wang added that out of the 120 million units to be sold this year, half of them will be customized by China Mobile -- presumably so that it can choose its own bloatware, right? As for TD-LTE, China Mobile expects its 4G technology to bloom in China some time between 2014 and 2015, as it continues to help the development of devices that natively support five modes (GSM, TD-SCDMA, UMTS, FD-LTE and TD-LTE) along with 10 to 12 bands. Obviously this is the very reason why China Mobile is getting cosy with Qualcomm, the company who has SoCs that support all these radios. Wang added that ahead of the full launch of TD-LTE, his company will be initiating user trials for TD-LTE data devices and phones throughout 2013 -- the first half of the year for the former, and the second half for the latter. Well, we only have three words for China Mobile: hurry up already!

    LTE technology is usually divided into two distinct camps, FDD-LTE and TD-LTE, that might as well exist in two different worlds: own a device using one and you can't access the other. ZTE is bringing some harmony to 4G through the Grand Era LTE. The smartphone can connect to both LTE formats on China Mobile Hong Kong's newly dual-mode network, keeping locals in the high-speed zone no matter which 4G format is available. As our friends at Engadget Chinese discovered in a hands-on, however, it's not quite seamless at this stage. Subscribers have to reboot to switch networks, and the Hong Kong take on TD-LTE access doesn't upload as quickly as its FDD counterpart. Even with those bubbles burst, the Grand Era LTE is still a solid phone in its own right, touting a 4.5-inch 720p screen, a 1.5GHz dual-core processor and ZTE's relatively light Mifavor interface sitting on top of Android 4.0. Check our video after the break to get a taste of the phone and the network -- although the clip is in Cantonese, the results are universal.

  • Clearwire sees wholesale revenues dip, LTE delays as it posts a $41.3 million net loss in Q3

    Clearwire's figures show that the network it isn't cool to love will be making placating faces at its bank manager for yet another quarter. It pulled in revenues of $313.9 million for the three month period, but with business costs (and depreciation) clocking in at $646.7 million, the company posted an operating loss of $332 million and a net loss of $41.3 million. If that wasn't bad enough, it's also hacked back a target to add TD-LTE to 5,000 sites before mid-2013 to just 2,000. A similar problem has occurred over at newly-minted majority owner Sprint, which has found itself a quarter behind its own LTE timetable thanks to parts shortages -- so let's hope the folks over at Softbank can help both companies improve their estimating skills.

    China's Minister of Information and IT doesn't always explain his decisions in much detail, leaving us to ponder a sudden acceleration in his plans to roll out LTE. Miao Wei had previously indicated that 4G permits wouldn't be issued to operators until at least 2014, but now the word according Xinhua News is that this bureaucratic phase will be completed "within about a year." Perhaps those TD-LTE base stations are being built faster than he expected, or maybe the idea of being beaten to the punch by a little island nation is just too much. [Photo credit: China.com.cn]

    You likely know the uncomfortable feeling when family members refuse to talk to each other, and such is the case with FD-LTE and TD-LTE -- two similar but incompatible LTE technologies that've gained traction across the globe. Now ZTE is looking to play peacekeeper with its MF820S2 USB modem and MF91S mobile hotspot, each which speak fluently in both LTE languages. While Marvell was the first to accomplish this feat with its modem chipset, ZTE's two globetrotting products are the first we're aware of that are ready for retail shelves. That said, both units seem best suited for users based in China, as the fallback technologies include only TD-SCDMA and EDGE. ZTE's USB modem is said to provide up to 68Mbps connectivity over TD-LTE networks and up to 100Mbps over the FD-LTE counterpart, whereas the mobile hotspot wields a 2,300mAh battery. As always, you'll find the full PR after the break.

    Sprint has declared that it's no longer Clearwire's majority owner in a move designed to shield the carrier should the worst happen to its troubled bedfellow. While Big Yellow is planning to supplement its own LTE network with Clearwire's TD-LTE backbone, it's looked to distance itself on the business side from a company that finds it very hard to make money -- requiring handouts from Sprint just to stay afloat.

  • Huawei partners with Intel to test TD-LTE interoperability in China

    In a classic case of east meets west, Huawei and Intel have joined forces to create an interoperability test lab that will focus on China's homegrown time-division LTE (TD-LTE) network. While the technology runs contrary to the more common frequency-division LTE (FD-LTE), the Chinese brand of 4G is situated to take root in the US under Clearwire's banner. Through its partnership with Huawei, Chipzilla -- a newbie in the smartphone arena -- will be able to engage in end-to-end testing of its mobile equipment and verify its readiness for TD-LTE. For Huawei's part, it plans to use the test lab as a means to court other handset and chipset manufacturers, and hence drive the adoption of TD-LTE. Naturally, we're left wondering the obvious: whether this unique collaboration will bring about Huawei smartphones with Intel Inside. Mum's the word on that one... for now.

    Clearwire's hardly throwing in the towel after that whole "WiMAX" thing; instead, the outfit has its sights firmly set on bringing TDD-LTE to the masses here in America, starting with an initial rollout in early 2013. A release put out today confirms that New York City, San Francisco, Los Angeles, Chicago and Seattle will be among the 31 cities where the company will launch the aforesaid network, though there's no breakdown on which of those metro markets will be forced to wait until "mid-2013" to get served. Speaking of, Clearwire's making no bones about the fact that "high demand hot zones" will be the ones targeted initially, and in a bid to outshine those LTE networks already live, President and CEO Erik Prusch is suggesting that his firm's 4G network "will show that not all LTE networks are created equal." Bold words, sir.

  • Sprint will activate LTE on the 800MHz band in 2014

    Sprint's Steve Elfman has said that the company's intending to activate an LTE service over its 800MHz spectrum by 2014. Big Yellow's already received 3GPP certification to turn Band 26 into super-fast mobile internet, the only remaining regulatory hurdle left to overcome is a thumbs-up from the FCC. The due date isn't set in stone, as it'll depend entirely on how quickly the company can force current iDEN users to migrate to its CDMA Direct Connect service. Meanwhile, LTE service in Atlanta, Baltimore, Houston, Dallas, Kansas City and San Antonio will activate across next year, with the company confident that it'll be able to keep pace with AT&T and Verizon's services by offloading traffic onto Clearwire's TD-LTE Network which should go live by June 2013. We can only guess that after that the announcement was done, Mr. Elfman looked at a picture of Philip Falcone and had to step outside for a little cry.

  • Chinese official: We're not issuing 4G licenses for another two to three years

    China isn't in a huge hurry get its own 4G network up and running, instead wanting to ensure the infrastructure is primed and enough compatible handsets are available before it launches. According to the head of the Ministry of Industry and Information Technology, Miao Wei, the country needs plenty more base stations -- beyond the existing 220,000 TD-SCDMA bases and closer to 400,000 -- before the government starts offering 4G licenses. China Mobile, the country's largest mobile network, already plans to have over 20,000 TD-LTE base stations in operation by the end of this year, stepping up to 200,000 by the end of next year. This particular type of LTE hasn't quite set the world on fire just yet -- only two operators have launched TD-LTE services and a genuine handset for the network remains absent. Upgrading existing 3G stations is likely to take around three years, according to the official. At least it gives ZTE more time to get the MT73 readied for ICS -- or perhaps Android 5.0.

    China Mobile announced a deal with Clearwire last fall to speed up the rollout of its TD-LTE network, and now China's largest wireless provider has revealed some additional details about when that rollout will take place and just how big it will be. Speaking at Mobile World Congress, China Mobile president Li Yu said that the company will have over 20,000 TD-LTE base stations in operation by the end of this year, and a full 200,000 up and running by the end of 2013. That initial deployment will occur in the six trial cities already announced, as well as three additional cities confirmed at MWC: Beijing, Tianjin and Qingdao. Two of those cities, Hangzhou and Shenzhen, are expected to have full TD-LTE coverage of their urban areas this year, while the others will have more isolated coverage until the next phase of the deployment begins.

    Clearwire's been promising us that speedy LTE network for quite some time now. The good news is, we may have a clearer view of when to expect the waves to start flowing. During yesterday's Q4 earnings call, CEO Erik Prusch said his company plans on rolling out its LTE tides by June of next year, with the help of 5,000 wave sites around the US and a "longer-term" plan of adding about 3,000 more. The 2.5GHz spectrum will take over the WiMAX regime you've grown to love, and while we're still many handsets and slates away from testing it out, it's something all you Now Network users can happily look forward to.

    So, Nokia Siemens Networks wasn't fibbing when it said it would re-focus its efforts on mobile broadband. It's just announced a 'six pipe' radio head upgrade for time division LTE (TD-LTE) base stations that can boost capacity by 80 percent and coverage by 40 percent compared to a traditional three-sector site. Alternatively, the same replacement can be used to reduce a station's running costs, by allowing it to cover three sectors using a single radio head. As far as we're concerned, anything that recalls OK Computer is a good thing, but if it speeds up carriers' shift to LTE then it's even better. Meanwhile, for those who still want to invest in CDMA, Nokia Siemens is pushing it's 1X Advanced technology, which also promises big improvements in voice and data capacity as well as energy efficiency. Read on for more technical details in a PR double-shot.

    Here's a funny one we spotted at China Mobile's booth at Mobile Asia Congress: a ZTE Android phone powered by a MediaTek chipset that supports TD-LTE, TD-SCDMA, GSM and dual SIM! Of course, given that China Mobile is currently the exclusive carrier to the TD-SCDMA technology, we're not expecting this peculiar device to pop up anywhere beyond the Great Wall any time soon; but knowing that there's a dual-SIM LTE phone somewhere on this planet still makes our day. Spec-wise this MT73 prototype features Android 2.3.4, an 800MHz processor, 1GB of RAM, a 4.1-inch 854 x 480 LCD with capacitive touchscreen, a five megapixel main camera, a VGA front-facing camera and a 1,100mAh battery. As per usual ZTE build quality, there's an inevitable cheap feel upon laying our hands on this phone, but we'll give ZTE the benefit of the doubt and wait for the final version. As for a launch date, the folks at China Mobile said it'll depend on when will the government issue a commercial license for TD-LTE. To keep you occupied for the time being, we have a hands-on video right after the break.

  • China Mobile wants some of Apple's App Store revenue

    China Mobile has been quick to talk about the iPhone to the media, but its internal talks with Apple are apparently not as fast and furious. According to a report from AllThingsD, China Mobile and Apple are "firmly engaged" in a discussion about the iPhone, but technology concerns and money squabbles are slowing things down. Unlike most wireless carriers which are falling over themselves to get the iPhone, China Mobile is doing the opposite and supposedly pushing Apple to give it a piece of the App Store revenue. Giving a carrier a cut of this lucrative business is something Apple has never done before and likely doesn't want to do, but China Mobile may believe it's in a good position to make this request. Everyone, including China Mobile, knows that Apple wants to expand further into the Asian market and China Mobile may be using its large subscriber base to squeeze this extra money out of Apple. China Mobile may also feel it doesn't need the iPhone right now. The wireless carrier confirmed it already has 10 million iPhones on its network and is apparently happy with that number. Apple may be likewise reluctant to ink a deal as it may need more time to develop the TD-LTE technology that's compatible with the carrier's network. Most likely, Apple and China Mobile will be ready to sign on the dotted line sometime next year when Apple introduces its LTE-based successor to the iPhone 4S.

  • China Mobile claims 10 million iPhone users

    China Mobile Chairman Wang Jianzhou told Reuters that its wireless network is home to over ten million iPhones. This number is a very small part of China Mobile's 600 million subscribers, but it's surprisingly high for a carrier that does not currently sell any model of the iPhone. These iPhones on China Mobile are either purchased directly from China's five Apple stores, converts from China Unicom which does carry the iPhone 4 or are iPhones obtained on the black market. It's well known that many iPhones being sold in China are smuggled in from foreign countries and sold to customers in open air markets. This illicit market may face some competition as China Mobile hopes to carry the iPhone when Apple manufacturers a version compatible with the carrier's TD-LTE standard for 4G. According to Wang, China Mobile does not have a contract with Apple, but Apple has supposedly promised to support TD-LTE when it develops an LTE-enabled iPhone handset. Steve Jobs and Tim Cook have reportedly visited with China Mobile executives to discuss this technology and a possible carrier agreement. China Mobile is the world's largest wireless carrier and an official agreement would vastly increase the number of potential iPhone owners. Though China Mobile has publicly said several times that it wants the iPhone in an offical capacity, Wang isn't upset by the number of unauthorized iPhones on China Mobile's network. Wang said, "The total number of iPhones in China Mobile's network has reached 10 million -- and we didn't pay any subsidies." That's a nice hidden benefit.

  • Sprint converts its network to LTE, plans 'aggressive rollout' to be completed by 2013

    We knew more or less that an announcement of this sort was coming. Back in July, Dan Hesse had teased us face-to-face with the promise of a "great story this fall around 4G," and now the time to tell that tale has arrived. At its strategy event today, Sprint finally went public with plans to "simplify its network" by converting its 1900MHz holdings and LightSquared's 1600MHz spectrum ("pending FCC approval") to LTE, an industry favorite. Helping the operator make that transition is the swath of 800MHz spectrum it reclaimed from the, now defunct, iDEN push-to-talk network -- which had been a drain on the company's resources. This spectrum, acquired from Nextel, will be phased out by mid-2013 and rolled into LTE. The company plans for a rapid deployment of this new 4G network, with the first LTE markets and handsets to hit in mid-2012, and the full rollout mostly completed by 2013. Current subscribers signed up for WiMAX plans won't have to worry as their devices will continue to be supported throughout 2012. Beginning tomorrow, Sprint's consolidating its 4G LTE (including LightSquared), 3G and Direct Connect networks into one single architecture. All the major technical milestones, such as test calls and field integration, have cleared their hurdles and work on over 22,000 cell sites are currently in process. Samsung, Alcatel Lucent and Ericsson have partnered with Sprint to install multimode 3G and 4G base stations to handle the network's future traffic, essential for deploying the multitude of frequencies required by hosted devices. Prospective iPhone 4S users on the network will be able to take advantage of better signal strength and improved voice service as Sprint intends to also offload the latter onto 800MHz. Expect a steep "reduction in roaming costs" and deeper signal penetration throughout the operator's expanding national footprint over the course of the next two years. Naturally, LTE speeds on this new network will be significantly improved over the currently in-use WiMAX, and a planned implementation of WiFi offloading should help to cut congestion by 20 percent. By the end of next year, Sprint aims to have a combined WiMAX/LTE population coverage of 176 million -- with 123 million covered by LTE and 76 million overlapping both. When the network build-out is nearly complete in 2013, the company should have over 250 million blanketed in LTE, far outstripping the stagnant 120 million served by WiMAX.

    At this point, it's pretty much an open secret that Sprint needs to hitch its ride to LTE to stay in the wireless game. CNET caught wind of the operator's intended 4G plans ahead of its scheduled October strategy announcement -- an event at which many in the industry expect Sprint to lay out its LTE cards. According to the report, the Hesse-led network's been hard at work installing the necessary infrastructure to convert to its towers to FD-LTE, which is the same flavor of LTE as Verizon and future partner LightSquared. Using the iDEN spectrum it acquired from its Nextel purchase, Sprint reportedly plans to set up 4G shop on those radio waves, and make use of current WiMAX provider Clearwire's proposed switch to TD-LTE by incorporating chipsets in future phones that accommodate both frequencies. The network changeover, rumored to cost Sprint somewhere in the range of $4 - $5 billion, should get carried out over the next five years, laying the groundwork for a true three-way 4G race.

    At PT/Expo Comm Nokia Siemens officially decided to dip its toes in the 4G dongle and router waters, unleashing the USB-lte 7210, the CPEi-lte 7212 and the CPEo-lte 7210 on the public. The three different devices all use TD-LTE to hit speeds of 102Mbps down and 51Mbps up. The USB-lte (pictured on the right) is, obviously, a plug-and-play USB modem for getting your laptop (or desktop, we suppose) online using a cellular network. The CPEi and CPEo are 4G routers, with WiFi radios and Ethernet jacks that allow you to spread the 4G wealth. The difference being the CPEi is designed for in-home use, while the "o" in CPEo stands for "outside." Pricing and availability are still a mystery but, since no carriers here use the time division-duplex flavor of LTE, don't except to see them land on American shores.

    The world's largest mobile operator and the heretofore scrappy WiMAX provider have linked arms to accelerate the rollout and adoption of time-division LTE (TD-LTE) across China. While there's little chatter about an infrastructure build-up itself, China Mobile and Clearwire have established an agreement "to cultivate a robust device ecosystem that supports multi-mode, multi-band devices with minimum component complexity and cost," with particular emphasis on the common 2.5GHz spectrum. More specifically, the collaboration will work to build up a high volume of TD-LTE chipsets and devices for commercial availability in 2012. If Sprint were to purchase (or make a significant investment in) Clearwire, this deal could be especially important, but for the time being, the company is finding some independence from the uncomfortable love triangle that's brewing between itself, Sprint and LightSquared. While there's no telling what sort announcement will come on October 7th, it's nice to see Clearwire secure an international lover that's willing to commit to a shared LTE vision. You'll find the full PR after the break.
