Gee just because it hasn't been done in the past doesn't mean it can not happen in the future. Reading here in the future not all LTE will be compatible anyways and Verizon roaming may disappear in the future.
Nextel towers are done with. Why not ad back a few thousand in some higher traffic higher growth areas or where people visit and travel. There are places in summer that there are way more visitors than people living there year round. Same with winter ski areas where seasons are reversed.
Also some areas there are still new subdivisions going in and more people living there or unfortunately going to live there in the future.
I can think of some places microwave in some backhaul add to an existing cell tower for probably Verizon owned by whoever, then get the visitors traveling through, get local sprint customers, and since Son bought Clearwire give locals internet that way also. No dsl or very pathetic, absolutely no cable, and maybe a small WISP in these areas. Usually only desperate or nerds go for wisp.
There is no local small cell company to buy so only options are to ignore like some here just keep repeating or build your own. Hope Son sees a future to build your own in some select areas.
Or just ignore the possibility of some at least to me and my wife key 3g roaming areas disappear in the future when 4g takes hold with all cell companies.
ATT and Tmobile had no signal only Verizon and Sprint roaming. If those areas for Sprint go away my wife would not be happy. Plus some key areas no Sprint or even Sprint roaming but are Verizon my wife has family in and as said major tourist areas if there are no fires and do have a rowing population base unfortunately. But lets scream old Sprint and how poor we are with no vision for the future. We switched to Sprint and did not have a grandfathered unlimited data plan. We do not use that much but caps and overages can suck. So we went Sprint as i saw a future with it. Let the myopic penny counters with saying it can not be done bash.
S&P did the same bash as no vision and maybe some bigger companies nudge the drop. Big two hate competition and would not doubt talked in someone ear. Son has vision and probably predicted the wrong credit drop back lash even though bet he does not agree about the risk level.
In town urban may get taken care of by small cell stuff that would help Clearwire.
But still rant here about how it is not money smart and impossible.
