Just to keep everyone updated that Clear is not just sitting on it's hands, at least not in China. Clear is testing handoff b/twn FDD and TDD, also testing will continue in the Phoenix area. Good news for those in the Valley of the Sun when Sprint has the chipmakers puts Clears freq on its chips.

HONG KONG and BELLEVUE, Wash., Jan. 17, 2012 (GLOBE NEWSWIRE) -- China Mobile, the world's largest mobile network and customer base in the world, and Clearwire Corporation (Nasdaq:CLWR), a leading provider of 4G wireless broadband services in the United States, today announced, in conjunction with the Global TD-LTE Initiative (GTI), an agreement on common test specifications and joint interoperability testing (IOT) for TD-LTE devices in the global band configurations, including 2.3GHz to 2.7GHz. This important step forward will enable the companies to further accelerate development of the TD-LTE device ecosystem, especially in multi-mode, multi-band LTE devices.

 

Beginning this month, China Mobile, Clearwire and other GTI operators will establish 4G mobile broadband labs featuring a joint test platform and IOT environment for TD-LTE devices. The expected availability of the Quad-Band LTE 2.3-2.7 GHz spectrum range, in addition to certain other bands like 1.9GHz, as well as FDD and TD-LTE mobility interactions, makes it an ideal global configuration for mass 4G marketing worldwide. The labs will allow for the evaluation and qualification of commercial TD-LTE devices simultaneously in the U.S., China, and other promising markets, using common testing methodology, equipment, and infrastructure.

 

"The unmatched spectrum portfolio underlying Clearwire's planned LTE network has the potential to deliver faster speeds and with greater capacity than any current or proposed 4G network in the United States," said Dr. John Saw, chief technology officer of Clearwire. "Close collaboration with global wireless leader China Mobile accelerates the development of multi-mode multi-band TD-LTE and LTE FDD devices and provides the common test specifications OEMs, ODMs, chipset vendors and other critical component manufacturers need to rapidly develop and commercialize products to serve this massive global marketplace."

 

"Converged with LTE FDD, TD-LTE has become the major global 4G technology for unpaired spectrum," said Mr. Li Zhengmao, Vice President of China Mobile. "Our goal is to build efficient, low cost common infrastructure and terminal for different global markets with different spectrum to support mobile internet. By closely working with global operators such as Clearwire, we could leverage the experience, expertise, and scale to achieve this goal. This is also the reason why we create GTI and promote it jointly."

 

Clearwire plans to conduct its TD-LTE common IOT in Phoenix, AZ and Herndon, VA. China Mobile's testing will be carried out in Beijing and other TD-LTE trial cities. The joint test platforms will be open for device IOT by key participants in early 2012.

I got around to writing a story about it this afternoon. It's exciting to think about a Worldwide LTE band with full operability. And Sprint would be the only U.S. carrier with devices that will operate on it. It's exciting stuff.

What are you doing to me? I go and get coffee from the Keurig and sit down, read your last post and almost launch hot coffee through my nose. Using quick and Clearwire in the same sentence. LOL

It could take up to a year for chipsets to be perfected for the plans that Clear & China Mobile have. I sure hope that they don't make the mistake they all did with WiMax. We sure need devices with better battery life than the 5 hours of talk time I get now. I'm going to be patient with Sprint & Clearwire & China Mobile this time.

    • Luckily, that hasn't arisen in my area where I am, aside from having B14 (well, ALL of AT&T signal) not work at all in Coosa county, Alabama. I wish there was a service for first responders that would go to ANY available carrier, provider, etc..and in the absolute worst case scenario, would give us service. I've been on an ambulance, trying to find an address, and my driver actually had to pull over and we pulled out a map book and tried to find the road using the "old fashioned way".. and that takes valuable time away that sometimes may be vital to someone surviving. BUT, I will say that I've only seen that in Coosa county... both my Tmo and AT&T phones had zero service and I couldn't get GPS, and neither could my driver (VZW service). Maybe satellite will help with that in those times where that occurs.. but that's an extreme example.     Edit to add: Let me add some context to this.. Coosa county isn't regular coverage area for my job.. so it's not a regular thing that we are dispatched to Coosa county.. and actually, there's been a change and that county now has it's own ambulance service that operates.. so the only time we might receive a request is if it's a multiple casualty scenario, or it's a transfer going home from our contracted hospital.  The way that reads above, it may seem like we are just out without some sort of GPS gadget to direct us on where to go, but for the most part, we know our coverage area pretty well. Dispatch can also give us cross streets for reference inside our coverage area (and our home county). Coosa just isn't a regular area for my job to run in. 
    • "Priority" doesn't mean "exclusivity."  When emergency services don't need B14, AT&T can use it for everyone else.  The trade-off is that when it is needed for emergency services, they not only get all of B14, but they have also arranged for priority on the rest of the AT&T network as well.  Beats having spectrum sitting unused most of the time and then not having enough when disaster strikes, as it could be without a partnership with a wireless company like AT&T. - Trip
    • I've wondered if being on the first responder plan has the priority over other 'regular' lines in the same way firstnet does (or, supposed to do with B14...I've seen normal customers on AT&T hit B14 so it's not {specifically} for Firstnet only)...  
    • T-Mobile prices people pay are all over the map. The free lines are key, so take them if ever offered again.  Your priority level would be a key factor for your price.  Only T-Mobile would know the average prices people pay.  Samsung has been offering very good deals at time of new model introductions so I have gone that route for factory unlocked, which allows me to also have a Verizon priority MVNO for when T-Mobile signal fails or I manually override.
    • I also wanted to post a speed test result.. I only do these once in a while from my home area because we are gonna be the last to see changes, like load balancing.  Right now they are digging all over the place for fiber installs, so I'm not sure what the hold-up is on making the upload speed a little more in-line with download speeds, but here is the most recent from my area:   https://www.speedtest.net/my-result/a/10133670525
