The Continuing Wonder of the Walkie Talkie

A digital walkie talkie, despite being �digital�, does not work like regular communications technology that majority of the market knows. That is both its advantage and disadvantage. On the positive side, a walkie-talkie does not require network connection unlike many cell phones. Instead, these walkie-talkies uses short-range wireless technology which allows them to work where regular cell phones won�t. Walkie-talkies are battery-powered transceivers, meaning they can both send and receive radio messages. They have a half-duplex channel, which indicates that only one walkie-talkie on a channel can transmit a signal at one time, although many radios can receive that same signal. But this is also its limitations. Since it does not work based on satellite networks, it has limited range and do not afford the same expansive geographical coverage
