Re: LTE is not nirvana
said by Automate:WiMax can use TDD or FDD. Neither is "more compatible" with the 2.5GHz frequencies.
What most people don't realize is that LTE is not some kind of nirvana where everything is compatible. There are actually two LTE standards, LTE FDD and LTE TDD. Verizon, AT&T and MetroPCS are all using LTE FDM. Clear, on the other hand would most likely go with LTE TDM (also known as TD-LTE) because it is more compatible with the 2.5 GHz frequencies they own. TDD is time division duplex, the same technology that WiMax uses. In a way you could say that WiMax is closer to being compatible to the LTE that Clear is likely to switch to than what Verizon is rolling out. It would be easier for a chip to support both TD-LTE and WiMax than Verizons LTE and WiMax.
I was talking about TD-LTE being more compatible since the WiMax they are using in those frequencies is using TDD

said by Matt3:While theoretically true, FDD WiMAX has not been deployed anywhere in the world and is not commercially available. FDD requires paired channels while TDD does not. That probably isn't a problem in the US but some countries either don't allow or don't have paired channels available at 2.5 GHz.
