If a college normally bans the use of personal WiFi routers on campus, can they enforce that rule against a student who is a licensed amateur radio operator and is using the router under amateur radio regulations (Part 97; WiFi is normally Part 15)? Would PRB-1 apply in this case?
The ARRL has a page that explains PRB-1. This FCC report and order requires local government (usually the zoning authorities) to accommodate amateur radio, especially the antennas. Nothing from the FCC gives amateur radio operators a privilege to operate amateur radio while on private property, against the wishes of the property owner.
If the college is operated by a city or state, there is a small chance they might be considered a local government for purposes of PRB-1, but one would be trying to apply the report and order to a situation that is not what PRB-1 was aimed at.
