A walkie-talkie (more formally known as a handheld transceiver) is a hand-held, portable, two-way radio transceiver, is a wireless Talk Device. Originally developed for the Canadian government during the Second World War by Canadian Donald L. Hings, similar designs were created for other armed forces, and after the war, walkie-talkies spread to public safety and eventually commercial and jobsite work after the war. Major characteristics include a half-duplex channel (only one radio transmits at a time, though any number can listen) and a push-to-talk 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 his immediate vicinity. Hand-held transceivers may be used to communicate between each other or to vehicle-mounted or base stations.

The wrist walkie-talkie (come with a wireless headset) has become popular also because of the U.S. Family Radio Service (FRS) and similar unlicensed services (such as EURO's PMR446 and AU's UHF CB) in other countries. While FRS walkie-talkies are also sometimes used as toys because mass-production makes them low cost, they have proper super heterodyne receivers and are useful communication tools for both business and personal use. The boom in unlicensed transceivers has however been a source of frustration to users of licensed services that are sometimes interfered with.Use of the GMRS frequencies (USA)requires a license, however most users either disregard this requirement or are unaware.
