- Aloha 14y agoTo an extent, yes. That said, for universal wireless anything, you need a considerable block of spectrum. Consider that between T-Mobile/Sprint/Clearwire/AT&T/Verizon in the Seattle market, they hold something like 400+ mhz of spectrum. To provide this kind of service, you would need a similar (though not as large) block of spectrum. If you just looked at LTE or WiMax, to roll out a nationwide footprint, you would need something like 250 mhz of spectrum, and that includes backhaul pairs, and this is to provide enough carriers per site that most people could get a 'similar to cable internet experience'. There isnt 250 mhz of spectrum (other than the huge swaths the government has held for itself) in the bands that are useful for both rural and urban environments.
