The Different Types of Two Way Radio
A two way radio is also known as atransceiver. These radios are used for both for sending and receiving data orsignals. These radios can either work on analog technology or a digitaltechnology. When analog technology is used in these radios, the transmissioncan be done clearly even for very weak signals. However, in analog technology,only one thing can be done at any given time i.e. data can either be vent orreceived. When digital technology is used, data can be sent and receivedsimultaneously and also more data can be sent.
Two way radios come in two styles. Theseare duplex and simplex styles. In the simplex radio, only one channel can beused at any instance of time. This means that only one person can send data ata time. The most popular type of a simplex radio is the walkie talkie. Theduplex radio is the one in which different channels are used for transmissionof data. This means that any given time, the use can both send and receive databut using two different channels.
