A two-way radio is a radio that can
both transmit and receive (a transceiver), unlike a broadcast receiver which
only receives content.
Two-way radios are available in
mobile, stationary
Base
Station and hand-held
portable radio
configurations. Hand-held radios are often called
walkie-talkies or handie-talkies. A push-to-talk or Press To Transmit
button is often present to activate the transmitter.
A mobile phone or cellular telephone is an example of a two-way radio that
both transmits and receives at the same time (or full-duplex). It uses two
different radio frequencies to carry the two directions of the conversation
simultaneously.
A
mobile radio or
portable radio is an example of a technology that both transmits and
receives at the different times. It can use a separate transmit and receive
frequencies (or half-duplex).
Or it can use the same radio frequency (simplex communications) to carry
the conversation one way at given time.
