Radios are communication systems that send and/or receive electromagnetic waves.

Wireless modems transmit modulated data using electromagnetic waves.

Terrestrial and satellite radio service providers transmit radio programming over satellite, cable networks and over open airwaves

Radio modems are radio frequency transceivers for serial data.

Radio frequency identification (RFID) products read or write data to RF tags that are present in a radio frequency field projected from RF reading/writing equipment

Radio Receiver ICs support worldwide radio band requirements, including FM, FM radio data system (RDS), AM, long wave (LW), short wave (SW) and weather bands on a chip

Antennas are structures or devices used to collect or radiate electromagnetic waves.
