Quansheng TG-D5 digital radio scanners

Digital Mobile Radio (DMR) is an open standard for professional digital radio standard specified by the European telecommunications Standards Institute (ETSI) and is used for digital radios sold worldwide. Those radio protocol DMR operate on a standard channel width of 12.5 kHz, the band of 400-470MHz or 136-174 that are commonly used in mobile radio networks. Unlike other digital technologies, for example. TETRA system can operate in analog mode and therefore operate at current existing analogue radio networks and are therefore suitable to gradually replace the original radio network. DMR protocol uses to access two channel multiplex The slot time. Thanks to this approach doubles the capacity of radio networks over standard FDMA digital channel. This may be one frequency to communicate simultaneously on two independent channels, or communicate and transfer data such as GPS simultaneously. DMR radios to the system used in networks with high demands on quality and reliability of communication. The manufacturers of these radios try to have the best possible comfort functioning radios and their usage for both small and large radio network. Thanks to people smugglers is possible using the Internet to connect individual groups of radio communication (centers) worldwide.
