RF
Broadcast spectrum band
RF stands for radio frequency—the range of electromagnetic waves used for wireless communication, from AM radio to Wi-Fi to satellite signals.
The term appears constantly in electronics and telecommunications: RF interference, RF shielding, RF engineer.
An RF signal carries information through the air rather than through wires.
The device operates on standard RF frequencies.
