As others have said internet can be had through smartphones and tethering. However you can easily set up a network at regionals with just one phone and sharing the connection through one computer and then with a switch to a few more. There may be lag present but it will work if your team has only one smartphone available.

Overall, this looks like an amazing solution for scouting and 2073 will definitely be using it at the Sacramento Regional.
