Hi all, 

A friend of mine is trying to set up a network in a location where there is no fiber (or copper) for many miles. As bandwidth requirements are low (<1M for the foreseeable future) but uptime is important, he was looking at using multiple cell modems from separate carriers as redundant uplinks. I am concerned that different cell carriers might be using the same transport providers to a given tower, so that wouldn't be truly redundant. Another option would be using a satellite provider as a backup for cellular. (The high latency that comes with satellite is not an issue.) 

A fixed-radio solution would likely be too expensive upfront as it would require building towers. 

Am I missing any other options or considerations?
