There is plenty of unused spectrum especially from military. It takes lobbying power and money to obtain. I always wonder why carriers don't implement "zoned metering". Their build out deployment seems slower than a government agency, which is insane considering all the money pouring in. I am in the air-ground communication industry and perhaps I don't know all the problems they face, but they just seem more eager to sign people up than building infrastructure. Especially AT&T. At least Verizon build out deployment has been fast.
there is unused spectrum, but how useful is it?
most, if not all of the current useful spectrum are taken/reserved (700, 850, 1700, 1900...). if you want to use new spectrum (like Sprint's 2600), you need people using new phones. it's more of a long term solution. I would like to see 2G/3G/CDMA deprecated, and everyone using LTE + VoLTE (5mhz of LTE gives you 200 active users @ full speed around 20mbps, vs 5mhz of 3G operating at 3mbps?)
I doubt carriers will move to zoned metering. it's difficult to implement, and how are you going to sell it to your customers? (if you go to NYC, you only have 1GB. If you go to Texas, you get 10GB?)
I guess it depends on how good the existing infrastructure is, and how "needy" you are to get things done. Look at t-mobile. they started LTE deployment in March 2013, and got a lot done 1 year later. some of it is due to efficiency (they had enough existing backhaul in places where they were using HSPA+ 42mb/s, their purchase of MetroPCS was great because all their frequencies were aligned...), their existing 1700/1900 frequences complement each other and can switch b/w 2G/3G/LTE easier,
So I am sitting here with 40 down and 6 up. If I start streaming Netflix, do I actually affect crowded San Francisco or Atlanta airport. Trust me, unlimited users on Verizon are not the problem to certain congested areas. It's their own infrastructure and over crowded subscribers posting selfies.
I still don't blame unlimited users. Especially once on throttled plans, they can stream video on at crippled speeds 24/7 and it shouldn't effect the network anymore than a normal user.
i disagree with the politics / bureaucracy of things especially for Verizon/ATT, but on a technical side, it's not easy
the whole thing about unlimited and wireless spectrum to me is: wireless spectrum is finite. if you use it, someone else can't use it.
if you have unlimited, it costs you $0 to use it, so you'll keep using it, while other people (paying $10/GB) can't access it.
too bad right?
