Are there any network protocol that we can use at competition?

For United states competitions 5GHz is used, I believe though in some other countries, 5GHz is a restricted band and 2.4GHz is used.
There is no reason one should have to shut off a bluetooth system unless there is an FTC completions also going on, as they do use a 2.4GHz system for their control system (Bluetooth).

2.4 GHz IS used by the field. Every FRC event field has wireless networks in the 2.4 and 5 GHz bands - all the robots are on 5 GHz, but all field systems communicate on 2.4 (all referee touch screens, etc).

So yes bluetooth, and other 2.4 networks may not directly impact robot communications, but that doesn't mean they are okay - and you definitely will be found and told to shutoff any wifi networks on either spectrum. Although Bluetooth may not be explicitly named, if it is in the same frequency range and has a chance of interference then it really should be avoided.
