As a contractor for an FBO, is it okay for us to transmit Internet signals right above the tarmac? I have been looking for the FAA Regulations on this with no luck, we are contracted IT with a local FBO and they want to provide internet to all their hangers. The easiest way would be to put a line of sight connector for the network so we can pass the internet over it, HOWEVER it will shoot over the TARMAC and I am not sure if FAA prohibits that. It is only for ground operations the Airplanes won't be using it but I just wanted to cover myself before I did it.
There are no FAA restrictions on setting up WIFI transmitters and receivers at an airport in the United States.

WIFI transmissions do not interfere with the frequencies used by airplanes for operational purposes.
