Walkie talkie more formally mentioned as a handheld transceiver, could also be a hand-held, portable, two way radio transreceiver. Its development during the Second 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
Typical walkie-talkies resemble a telephone handset, with a speaker built into one end and a microphone within the opposite (in some devices the speaker is additionally used because the microphone) and an antenna mounted on the very best of the unit. they’re delayed to the face to talk . A walkie-talkie could also be a half-duplex communication device. Multiple walkie-talkies use one radio channel, and only one radio on the channel can transmit at a time, although any number can listen. The transceiver is usually in receive mode; when the user wants to talk they have to press a “push-to-talk” (PTT) button that turns off the receiver and activates the transmitter. Smaller versions of this device are also very fashionable among young children
