Since you don't want to rely on students phones are you extending that to tablets as well?

Sounds like you are looking at using a cellular access point on a PC and communicating to other computing devices over a wired connection. Meaning you are going to need a switch and likely a constant source of power.

A LTE connection (if available) should have no bandwidth issues assuming your scouting team doesn't pass the time watching netflix/youtube over your connection
