radio-frequency
Electromagnetic transmission band
Radio-frequency describes electromagnetic waves in the range used for wireless communication—from radio and television broadcasting to WiFi, Bluetooth, and cellular signals.
The term often appears in technical contexts: radio-frequency interference, radio-frequency identification (RFID).
As a noun, a radio frequency is any specific frequency within this range.
