I live in a rural area, but with access to lte. My config consists of Cradlepoint router, with 2 lte modem's connected , one from Verizon, the other from AT&T, used to also have sprint as well, but canned it due to them never upgrading speed of their networks. Connection speed varies from 22mbps to 44mbps via speedtest.net. I have two external antennas attached to the modem, which gives me solid 5 bar signals,
Latency varies constantly, 15-60ms variance.
Good news am have access, quick, semi reliable
Bad news, expensive $300/mo per carrier for 30gb per carrier per month, despite being set up highly available the lte modems hang frequently, yes the Cradlepoint resets and the system fails over to the other carrier, but it never fails that that both will fail at the same time when I need it the most. Those fails require a rest of modem, which can be done by the web interface. Latency varies heavily, 15ms-60ms.
As expensive as it is, it is a tremendous improvement over satellite based Internet. Prior to lte, I installed Hughes commercial internet service at my house. (Not the wimpy personal service, the big 1 meter dish based system). Satellite is an absolute last resort solution.
Voice over the lte, is great until a modem decides to mess up, then it goes from bad to dropped. Movies are capable to stream, but some services like Netflix, Hulu, do better recover than others. Gaming is non-existent. The latency varies too much, first person shooter become first person target.
Main issue is the obscene pricing. Att is cheaper than Verizon, but neither will deal on more than 50gb per month usage.
