It's called the Family Radio Service (FRS), and is designed to be an unlicensed, "Very Short Distance Two ... To avoid interference with GMRS stations, FRS radios will be required to use only 2.5 kHz deviation, half the usual narrow-band FM deviation of 5 kHz. Transmit audio frequency response is limited to 3.125 kHz.
