From what I understand, many of these phones will be looking for wireless access points - like robots and the field.
Yes, there was a large number of phones in one area, many of which I'm sure were using wireless. The robots, however, connect to the field on the 5GHz band, as opposed to the 2.4GHz band that most devices use(I don't think I've ever seen a phone that can connect on 5GHz)

What you're seeing is actually the Wireless SSID's that the field is broadcasting, not the robots themselves. You're unable to connect because of the WPA2 encryption that every team has to put on their robot's radios(via the radio kiosk) before they can compete. The field is configured with those encryption keys and any device connecting to it must have it as well.
