Winegard/AT&T TOGO (aka
ConnecT). Easy to install and configure. Can be used either as a "hot spot"
(convert cell phone signal to local WiFi) OR a WiFi extender/repeater if you camping location has adequate bandwidth to the rest of the internet
(personally I would not bother especially if work is paying for the data).
Connects
(wirelessly) to multiple device in the coach. If your phone supports it, you can make calls through it also.
EDIT : This is also supported on Verizon, but you have to change the SIM card. Not real easy if mounted on the roof.
