You really can't compare these fixed LTE deployments to rural areas to what we get in urban and suburban markets. Obviously people who have access to cable and FiOS aren't going to use fixed LTE. DSL is iffy, it depends on how reliable the line is, copper networks haven't been maintained very well in many parts.
These deployments primarily target areas that may have only one Satelite
Even my gramma on Centurylink 1.5mbps line can blow thru the 60GB cap in a month. A 1.5mbps line can do 16gb a day. Sad, but true, that LTE services are a fail and overpriced, for sure.
I have no cable tv at my IL residence ( just outside the chicagoland area) and OTA reception is spotty at best, My retirement age mother watches netflix and she occasionally babysits my nephew on weekends and guess what on a 3.0 mbps line EVERY month since Feb 2012 A T & stinking T has hit me with overages (over the 150GB cap) on DSL so it can easily be done. U verse is not available here and neither is Comcast.
