Walkie-Talkies,
Two Way Radios
A walkie-talkie (more formally
known as a handheld transceiver) is a hand-held, portable, two-way radio
transceiver. Its development during the Second World War has been variously
credited to Donald L. Hings, radio engineer Alfred J. Gross, and engineering
teams at Motorola. Similar designs were created for other armed forces, and
after the war, walkie-talkies spread to public safety and eventually
commercial and jobsite work. Major characteristics include a half-duplex
channel (only one radio transmits at a time, though any number can listen)
and a push-to-talk (P.T.T) switch that starts transmission. Typical
walkie-talkies resemble a telephone handset, possibly slightly larger but
still a single unit, with an antenna sticking out of the top. Where a
phone's earpiece is only loud enough to be heard by the user, a
walkie-talkie's built-in speaker can be heard by the user and those in the
user's immediate vicinity. Hand-held transceivers may be used to communicate
between each other, or to vehicle-mounted or base stations.
