What is a walkie-talkie? This is a standard one-way radio that uses radio waves to communicate wirelessly on a single frequency band. It was first invented in the 1930s by Donald Higgs and Alfred Gross. It was called two-way radios or pack sets But it is known as a walkie-talkie because it allows the users to walk and talk at the same time. Each handset contains a transmitter, an antenna to receive and send radio waves, a loudspeaker that can function as a microphone as well, and a push-to-talk button. The loudspeaker cum microphone works like an intercom system.
How does the walkie-talkie work? People who communicate through the walkie-talkie must ensure that they are sharing the same frequency band or channel. Their handsets are all set to receive and the microphone cum loudspeaker is set to the loudspeaker. It keeps the device broadcasting when no one is talking. In case, someone wants to talk they can simply press and hold the push-to-talk button, and then the loudspeaker switches to the microphone. At the time of speaking, the words are converted into radio waves within the electromagnetic spectrum then, travel at the speed of light, and are picked up by the other handsets, so they are converted back into vibrations or fluctuating electric currents and the speaker’s voice is broadcasted by the loudspeaker. When the speaker finishes speaking, they say ‘over’ in order to inform the speaker, they finished speaking. Then, they leave the push-to-talk button and their handset goes back to listening mode.
