The Fastest Networks
Verizon's network
Also thank you for taking the time to do these tests and post the results for those of us who want to know but are unable to perform these kinds of tests ourselves.
At 2500 mhz it would take around 3 times the number of towers to cover an area compared to 700 mhz. High frequencies have low range. That's why those real high frequencies that sprint/clear own have never been particularly desirable for cell phones. They make for a very expensive network to operate.
Having a lot of spectrum is nice but it doesn't make your signal go further.
I'd have to do a little more in depth research on sprint's deployments but from my initial search it looks like sprint does voice and data using wimax. So voice calls and data share spectrum when people are connected to 4G. Voice and data sharing spectrum isn't uncommon though, it's uncommon to see them not sharing spectrum. Verizon is the only company i'm aware of who did voice and data on seperate bands because they had the luck that their 2G and 3G technologies could be simulcast AND they had 2 bands available to...

And Both LTE and Wimax will be fully data solutions in the future. VOIP for voice on the Data pipe.
The reason that verizon currently can't is because of what I stated in my previous post, they use seperate bands for their voice and data.
AT&T can do simultaneous voice and data because voice and data calls happen using the same standard over the same band.
On top of that, for sprint to cover the SAME area with coverage, they need more equipment. Also they need additional equipment to compensate with how much interferance that band gets compared to the 700, or even the 850/1900 bands get.
They NEED the additional spectrum to compensate for these issues, it doesn't provide them the advantage you're implying.
Yes, the higher spectrum means higher speeds are capable, but at a signifigantly higher cost. Which, considering they are charging less for their services than their competitors, could be a very real issue unless they start making money soon.
How many devices did Clear have 2 weeks after they launched? (they most likely had more than 2, because they had home routers) but honestly. the "we have 50 devices" pr spin is terrible. It seams like they're hiring the people Sprint fires, and that's not a complement.
And you're right, that extra speed won't matter. what will matter is coverage. So if, going forward, Verizon has to put up (on average) 1 tower to cover a region that it will take clear 4 towers to accomplish (higher bands have smaller radius', higher chance of interference, etc) how do you think the deployment will look once the "lucrative" city markets are covered? Which one, do you think, will have a faster rollout?

you can't just look at the amount of spectrum. You also have to check the efficiency. the 700mhz band is significantly more efficient at transmitting data compared to the 2500mhz band.
"[S]ignificantly more efficient at transmitting data" in what way? The Shannon-Hartley theorem requires no allowance for frequency or wavelength, only bandwidth & S/N ratio. All other factors being equal, 10 MHz bandwidth of 2500 MHz spectrum has the same information capacity as does 10 MHz bandwidth of 700 MHz spectrum.
