It's the "size of the pipe" upstream from the tower. A service called
"T1" offers 1 million bits per second, "T3" is faster still (45 million
bits/second????). These technologies are used to connect central
offices to each other. Customers with high bandwidth requirements also
use them. T1 will cost you somewhere between $500 and $800 per month
and handle something like 64 simultaneous voice calls. T3 is between
$4000 and $6000 per month. Fiber optic technology is also used.
Whatever the size of the pipe, you must share it with everyone else
using the tower. I suspect that each tower is limited to some modest
number of simultaneous connections. I suspect that by doubling up on
equipment each physical tower can act as two towers.
