8517 62 00 ... This subheading includes apparatus consisting of all the elements required for transmission and reception, in one cabinet or housing. Such is the case, for example, with walkie-talkies, which contain the batteries or accumulators required for their operation, or with transmitter-receiver apparatus, the power supply unit of which would be separate and connected to the apparatus by cable only.
Walkie-talkies are handheld, portable radios: they communicate wirelessly (using radio waves) on a single, shared frequency band. Each battery-powered unit contains a transmitter/receiver and antenna (for sending and receiving radio waves), a loudspeaker that often doubles up as a microphone when you talk into it, and a button that you "push-to-talk" (PTT).
Good to know
Walkie-talkies (originally called two-way radios or „pack sets“) were invented in 1937 by Canadian Donald Hings (1907–2004) and, around the same time, by American inventor (Irving) Alfred Gross (1918–2000).
