Cell coverage is sketchy at best. We do have cell phone back ups for reporting status of remote equipment but those failed as well this weekend. I think what we have decided to do is erect a 200' tower at the main facility and move the server to main facility and relay with a spread spectrum repeater off the proprietary spread spectrum radios hitting the repeater.

The microwave idea is being looked as an alternative at although nobody seems to know much about it (that I know).
