Executive Summary about Technology Used For a Two Way Radio by Robb Burdet
Two Way Radio Technology
A two way radio employs various technologies to send and receive data. The first two way radios employed a conventional technology in which operated on fixed channels. The use of conventional technology allows the use of only a single channel at a time even if the radio can operate on multiple channels. Simplex technology is yet another technology that is used for two way radios. In this a single channel is used by the radios to send and receive data.
Radios with this technology are the most common ones used for the purpose of communication. These types of radios are the most reliable ones for short distance transmission of data. The duplex technology when used for two way radios makes available two different channels, one for sending data and the other for receiving data. The duplex technology can be used in two ways in a two way radio. The second one is the full duplex technology in which the radios can send and receive signals simultaneously. This technology results in faster transmission of data.
Push to talk technology has also been used in these types of radios recently. Analog and digital technologies can also be used for these radios. When the analog technology is used, these radios transfer analog signals that have varying frequencies.
