I think that it would be wise to carry something like a 1W 4G antenna (if you can even get one). You'll be able to communicate with a tower possibly 80 to 100 miles away! Connect that into a switch and that can offer ethernet connectivity. That's where Windows tablets come in use! They have ethernet ports!

Otherwise, since you are running a webpage-based scouting app, just run the server at the competition! That is the reason why the scouting app I'm working on will be a fail. Even though I am heavily using WebCache to store the page, an internet connection will be required. Since you live in the West coast, like me, you might want to use Verizon or Sprint or ATnT. WiMax will give a 40 mile range! Even better, have a WiFi pack running a 16 Watt antenna (you'd have to build this yourself!) with you, and one copying your hotel's wifi! You'll get WiFi from anywhere in the city!
