Re: Too bad... LTE is not equal to H+, like EDGE, etc... There are a number of differences in the air interfaces(OFDM)/MIMO and LTE has a much lower noise floor. On top of that newer cells bring the amplifiers closer to the cell which yields better symbol resolution. You should check this out -- asu and this:

That blog discusses Sprint which is running on GHz freq just like Tmo will and outside most of the US lots of LTE countries.
I hear Sprint is going to try and run LTE or fixed on Clear spectrum which they have a crapload of it (over 150Mhz) and that is like 2.5 GHz. That will def require LTE-TD to work well, but technology always gets better.
We are entering a spectrum renaissance. All of these vacated 3G networks will be ripe for MVNO and cheap cell plans.
Now granted Verizon and ATT are sitting on spectrum that penetrates better and will allow them to be more picky, however that doesn't discount PCS/AWS-ish frequencies from running solid LTE. The question is how the refarm works and their upgrade path for EDGE cells. That will all require some shuffling until Vo-LTE takes hold for most of this decade.
When they more to LTE-Advanced you don't have to have dedicated download/upload channels. |

| Uh, I'm iansltx over at s4gru. I'm aware of that stuff.
Hence why I said "all else equal"; T-Mo's recent base stations are modulating PCS H+, AWS H+ and AWS LTE from the same remote radio unit. So it really is an "all else equal" situation, and given identical RSSIs (a legitimate way to measure LTE signal as long as you specify the carrier width...Verizon uses RSSI) for both techs, there are some RSSIs for which WCDMA will work and LTE won't.
We can talk about Sprint, but that's a different thread. You know, s4gru and all that. |
