At the end of my apartment's lease I'm going to be moving to an apartment complex that I know beforehand does not get cell service for geographic reasons. Now I'm not worried about data necessarily because I can always use WiFi but I can barely make calls over there. I've seen that Sprint has this Airave device available. I have a concern that isn't addressed on Sprint's site and that is if it lets just ANYBODY connect to it? I mean it's connected to my internet and I don't feel comfortable letting just anyone connect to it. For example, I don't really want my neighbors using my Airave to tether their phones for internet use using MY internet, bogging it down in the process.
