Walkie-talkie is a communication device that consists of low-level radio receivers and transmitters. It was originally developed for military communication during the World War II. Moreover, in the 1970s, the walkie-talkie became popular with the CB radio craze. Children were the biggest customers of walkie-talkie toy model. Many adults prefer 40 channel walkie-talkie or CB radios for two-way communication.
Early walkie-talkie works on the same radio frequency assigned to Citizen’s Band radios. Channel 14 was the most common channel used. This means that the conversation can be heard by anyone under the same channel. Federal Communication Commission does not require license for low-powered walkie-talkie due to their range limitations.
The device previously known as walkie-talkie have now enjoyed a revival popularity, even if most manufacturers call it two-way radio. These communication devices no longer use the old CB frequencies that can easily be intercepted. Modern walkie-talkies use the FRS or Family Radio System bandwidth that has 14 channels issue by the FCC, which give more security for conversations.
Modern two-way radios range as far as two miles. If a walkie-talkie ranges more than five miles, the Federal Communication Commission must license it. Adventurous users may buy two-way radio with additional features such as GPS, compass, hands-free voice command and weather channel tuner.
