re: Defining 4G: What the Heck Is LTE TDD?


No LTE TDD support in any Sprint devices yet. But yes, Clearwire & SoftBank both work on 2.6GHz band for TDD so that *could* open things up in the future.

re: Defining 4G: What the Heck Is LTE TDD?


Wasn't it in Sprint's plan to use Clearwire LTE TDD as an offload (or, really, an extenstion) of their network.


 


If that is true, then does every Sprint LTE phone also support LTE TDD (including the iPhone5)?


 


And if that is true, does that mean that every phone built for Sprint will also work on SoftBank's network?

re: Defining 4G: What the Heck Is LTE TDD?


Last I checked T-Mobile was owned by Deutsche Telecom and Verizon Wireless was 50% owned by Vodaphone, so it it not clear to me that any prohibition against foreign ownership of spectrum has any effect upon the practical control of spectrum.

re: Defining 4G: What the Heck Is LTE TDD?


Interesting theory, Headcoach & it makes some sense


One thing to think about is that Sprint's additional investment in Clearwire is supposed to close in a month & the Softbank deal not until the early part of next year. If the latter were to fall through, Sprint would still have majority ownership of Clearwire -- a status it previously tried to avoid.


It's not clear yet what, if any, roadblocks the Softbank/ Sprint deal might encounter. But it's probably a good risk for both of the companies. As you note, this may be the best shot Softbank has at gaining the spectrum it wants in the U.S. market. And for Sprint it's a way to hasten its LTE network buildouts.
