The Basics of Walkie Talkies
A walkie talkie is also known as a portable personal transceiver, a hand-held cell phone designed to work on a regular frequency between 3 Hz and 30 Hz. This spectrum of voices is particularly useful for brief communication exchanges between individuals who don’t want to be disturbed by an answering machine or voice mail. It can also be used for personal purposes, such as in communication with a distant relative, or to make a phone call to someone important. Some walkie talkies are equipped with a microphone so that you can use the device for communication. The most popular walkie talkie models are those manufactured by the Radio Frequency Identification Corporation (RFID), which have the additional feature of having a battery that can be recharged.
Modern walkie talkies have evolved into more sophisticated devices. There are now phones that incorporate the features of a walkie talkie. The first step to using a walkie talkie for communication is to purchase an appropriate base station. These stations are usually made up of a rectangular box with two receivers and two transmitters; these boxes need power from a battery or a solar panel.
To send a signal from one transmitter to another, the receiver needs to pick up the transmitted signals, which are then transmitted along the wires or cables connected to the base station. The advantage of this system is that the walkie talkie-transmitter and receiver are separated, and the conversation cannot be interrupted by interference. Most two-way radios that can pick up these radio waves are equipped with a microphone or a speaker so that they can be used with a walkie talkie.
