The DIPRA® mobile radios MS2217D and MS2221D are meant to be deployed as vehicular radios in low VHF and high VHF, respectively, and may optionally be operated in full duplex mode for voice communication. They comprise a transceiver part SE2217D and SE2221D and a handset with display for control and status information.
The TDMA method of Digital Mobile Radio with its two time-slots facilitates two connections at a time on a single pair of frequencies, even in full duplex mode.
Ethernet and optional RS232 interfaces enable the radios to be connected to on-board computers, fleet management and information systems. The display of the handset with its multiple lines and the alpha numeric keypad supports reading and typing of text messages.
An optional GPS receiver interlinked with an application to observe mobile users’ location on maps contributes to an improved safety of a mobile workforce and their efficient management.
