What frequency is used in wireless communication?

These products are organized by wireless technology and can be browsed under the “Solutions” tab. Although wireless communication is often associated with the 2.4 GHz frequency range, many devices and technologies use radio frequencies below 1 GHz (1000 MHz).

Radio waves are used for wireless transmission of sound messages, or information, for communication, as well as for maritime and aircraft navigation. The information is imposed on the electromagnetic carrier wave as amplitude modulation (AM) or as frequency modulation (FM) or in digital form (pulse modulation).

Wireless transmissions are made up of radio frequency signals, or RF signals, which travel using a variety of movement behaviors (also called propagation behaviors). RF communication starts when radio waves are generated from an RF transmitter and picked up, or “heard” by a receiver at another location .
