That is great where T has spectrum shortfall in major cities (Chi, LA, etc).
This will allow them to use WCS in open areas along w/ hotspots and the lower freq spectrum in buildings.
This is the only way to hodgepodge spectrum together.
In rural areas 2.3G will be good enough for connectivity because bandwidth needs are lower even though penetration suffers...It can make it through a moderate subdivision, however trees and rain will cause issues... Wifi in the house and low caps mitigate this. This will probably be better deployed on TDLTE or they get a 10x10 FDD, either way TDLTE is the better way to go because they can choose the tx/rx freq.... Not sure if they are going to allow this TD or FD, but TD would be better...
For sprint (Clear) they are sitting on boucoup spectrum which I guess TD LTE will allow them to do the same as T and also run on the 800 Nextel spectrum.
Whoever at VZW captured 700 Mhz should be given a jet. Brilliant move....
If all these things manage to fall into place, Sprint and AT&T will both have rock-solid networks. I have seen Sprint's Network Vision sites in action and they are phenomenal.
But whether or not they can manage to roll it out to their entire network in time to keep the ship from sinking is yet to be seen...and whether or not AT&T will actually spend the money to implement this is yet to be seen.
Although I have to disagree that WCS will be suitable for rural areas, if you've ever been out in the country and tried to rely on PCS service, you know what I mean. It doesn't just get slow, it just doesn't work at all.
VZW didn't "capture" the 700 spectrum, they paid through the nose for it. They had to. If anyone else had gotten their hands on the Boardwalk and Park Place of spectrum, they could have challenged VZW's rural monopoly. That's how VZW has stayed on the top of the heap all these years, they bought every cellular-band network they could get their hands on, spaced the sites far and wide, and sat back and reaped the rewards.
PCS and the higher-band frequencies can work in sparse, open areas. It just costs a hell of a lot more to do it. Where VZW can justify 1 cell site on the tallest hill to serve a rural town, PCS carriers would need 3 sites on both sides of the hill to compete, and sometimes there just isn't enough demand to make that scenario profitable.
