A walkie-talkie is a hand-held portable, two-way radio transceiver. The first walkie-talkies were developed for military use during World War II, and spread to public safety and eventually commercial and jobsite work after the war. Major characteristics include a half-duplex channel (only one radio transmits at a time, though any number can listen) and a push-to-talk switch that starts transmission. Typical walkie-talkies resemble a telephone handset, possibly slightly larger but still a single unit, with an antenna sticking out of the top. Where a phone's earpiece is only loud enough to be heard by the user, a walkie-talkie's built-in speaker can be heard by the user and those in his immediate vicinity (ear peices are optional!)
If you enjoy outdoor activities, enjoy riding your motorbike at weekends, work at a college or school, perhaps you work in a pub, club? Are you at home caring for a child perhaps? if you answered yes to any of the above then you would find a walkie talkie a very useful gadget. You may also need a walkie talkie if you move around a lot in your job. The benefit over mobile phones is that they are license free and do not have any associated call charges.
Walkie-Talkies are useful for short term events as there are no license fee's required to operate them. They also work back to back so you don't need any fixed repeating equipment.
Maybe now is a good time to think about using Walkie-Talkies for your site wide communications.......?
