Walkie-Talkie: An Overview
A walkie-talkie, also known as a handheld transceiver, is a portable two-way radio communication device that allows users to send and receive voice messages over short to medium distances. These devices operate on radio frequencies and enable instant communication at the push of a button, making them highly useful in environments where mobile networks may be unavailable or unreliable.
How Walkie-Talkies Work
Walkie-talkies function using radio waves to transmit audio signals between devices tuned to the same frequency or channel. When a user presses the push-to-talk (PTT) button, the device converts sound into radio signals and broadcasts them. Other walkie-talkies within range receive the signal and convert it back into sound. Communication is typically half-duplex, meaning only one person can speak at a time.
