How Does It Function?
The sound transmission starts when the push-to-talk switch is presses. A typical walkie-talkie has a built-in speaker which can be heard by the user himself or herself and other people in the immediate vicinity of the user. Hand-held transceivers are used either to communicate between two walkie-talkie, vehicle-mounted stations or base stations. A walkie-talkie is limited to a few watts of power output and a small antenna. The actual size of the unit limits both the battery capacity and antenna size. Its communication range is typically short, not exceeding the line-of-sight distance or within closed buildings or underground.
