A two-way radio is a radio that can both transmit and receive (a transceiver), unlike a broadcast receiver which only receives content one way. A push-to-talk or (Press To Transmit) button is often present to activate the transmitter. Hand-held portable two-way radios are often called walkie-talkies or handie-talkies. Two-way radios are available in mobile and stationary base configurations.

An example of a two-way radio that both transmits and receives at the same time (or full-duplex) is a mobile phone or cellular telephone, which uses two different radio frequencies to carry the two directions of the conversation simultaneously.
