Internet at Competitions

[yash101]

Whenever I use a hotspot (I rarely use one), I have the antenna set to <1mW, so you walk a few feet away and you lose connection, so that would be unlikely to cause any interference (except for the people around me)! However, let's just ditch wifi and use something like BT. As far as I know, I haven't heard of any restrictions on 3G/4G, especially because they operate on completely different frequency bands! Just as a teaser, has a single team ever used ZigBee to communicate internet connection? That would be a cool project.
