Walkie-talkies are small portable radios with both a receiver and a transmitter. They can both broadcast and pick up radio signals and make for an easy way to communicate when cellphone signals are not available.Continue Reading
Walkie-talkies are radios that both receive and transmit a radio signal. These two-way radios have both advantages and limitations. Their main advantage is that they are not dependent of a central network, unlike cellphones. This means you can communicate with a walkie-talkie in places with no cellphone coverage. They are still limited, since you can only talk with the people connected to the same channel, and a walkie-talkie's coverage is dependant on range. Walkie-talkies are push-to-talk, which means that you have to press a button to transmit your signal.
Commercial types of walkie-talkies usually have two frequencies: FRS and GMRS. Channels 1 through 7 are shared by both frequencies, channels 8 through 14 are FRS-only, and channels 15 through 22 are specific to GMRS. If you're in a channel, you only receive the signal and listen to anyone talking on the channel at the moment. Walkie-talkies are still commonly used, mostly by small businesses, deployed soldiers and by people who go travel in the outdoors, where cellphone towers are nonexistent.Learn more about Audio Equipment
