FRC. Yeah, they're understandably concerned about what happens if every single robot has 1 or 2 extra wireless communications channels. They announced at least once to the audience to turn off any hot spots as they're getting tremendous noise and channel swapping for the RoboRios.
If you use a RoboRio and wpilib, there's first class support to feed USB camera into the Rio, through the official match/field wifi for your robot, and to your laptop's Game UI.
They also specifically limit teams to low bandwidth to guarantee quality of service to each robot.
The FRC camera rabbit hole is deep - we run a fully custom gstreamer setup this year, plus a full ML/hybrid vision pipeline and two Apriltags cameras on Photonvision.
In years past, we even designed our own camera scheme with an implicit surfaces calculator so we could drive with/ship wireframes.
