A walkie-talkie, more formally known as a handheld transceiver (HT), is a hand-held, portable, two-way radio transceiver. Its development during the Second World War has been variously credited to Donald Hings, radio engineer Alfred J. Gross, Henryk Magnuski and engineering teams at Motorola. First used for infantry, similar designs were created for field artillery and tank units, and after the war, walkie-talkies spread to public safety and eventually commercial and jobsite work.
The debate about Walkie-talkies over phones
has been going on for some time. And we understand why. Walkie talkies are reliable
devices. They do not require call charge
or proximity to a cellular base station. And when an instant, real-time
interaction is needed, walkie talkies easily topple all other devices.
Walkie talkies are not some fancy gadgets that
you only take on a camping trip. In fact, you can rely on them for emergency
updates, weather forecasts, and communication when you are way out of network.
Typical walkie-talkies resemble a telephone
handset, with a speaker built into one end and a microphone in the other (in
some devices the speaker also is used as the microphone) and an antenna mounted
on the top of the unit. They are held up to the face to talk. A walkie-talkie
is a half-duplex communication device.
Multiple walkie-talkies use a single radio
channel, and only one radio on the channel can transmit at a time, although any
number can listen. The transceiver is normally in receive mode; when the user
wants to talk they must press a "push-to-talk" (PTT) button that
turns off the receiver and turns on the transmitter. Smaller versions of this
device are also very popular among young children.
