A walkie-talkie (more formally known as a handheld transceiver, or HT) is a hand-held, portable, two-way radio transceiver. … 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.
There is no such thing as an actual “three way radio”. You can buy any number of walkie-talkies of the same type, or indeed of different types, and they can all talk together if set up to do so. If you need 3 walkie-talkies, you can just buy 3 from any of our range of walkie-talkie radios.
