Kenwood NEXEDGE® mid tier hand portable, mobile radios and repeaters can be adapted to operate as dPMR units meeting with ETSI Standards TS 102 658 Modes 1 & 2*.
Kenwood NEXEDGE® dPMR equipment offers many of the features and benefits of NEXEDGE® NXDN including outstanding voice quality, extended range, spectrum efficiency and increased security, in an open standard, ETSI compliant multi-vendor format.
In addition, NEXEDGE® dPMR capabilities can be further extended to include multiple user groups by employing the following repeaters: NXR-710E, NXR-810E
To find out more about how NEXEDGE® dPMR be put to work for you, please contact an authorised Kenwood Communications reseller.
*dPMR Modes 1 & 2
dPMR Mode 1: The general purpose peer to peer application of dPMR for all forms of licensed PMR use. Mode 1 is part of the ETSI standard TS102 658.
dPMR Mode 2: The standard licensed PMR version that includes all base station and repeater functionality. Mode 2 is part of the ETSI standard TS102 658.
dPMR is a narrowband 6.25 kHz, 100% digital FDMA radio protocol for easy and rapid deployment utilising reliable low complexity technology.The FDMA protocol specified in TS102 658 ETSI standard complies with the European Harmonised Standard EN301 166-2 for use in 6.25 kHz channels. dPMR, an ETSI compliant, multi-vendor open standard The dPMR Association was founded in 2007 to provide a forum for all interested parties who wished to support the latest digital PMR technology. The association's membership includes equipment manufacturers, chip manufacturers, protocol and software developers and system developers.There are currently various equipment manufacturers with devices approved for dPMR operation and compliant to ETSI standards. dPMR Functional Levels dPMR Mode 1: A general purpose peer to peer application of dPMR for all forms of licensed PMR use. Mode 1 is part of the ETSI standard TS102 658. dPMR Mode 2: A licensed PMR version that includes all base station and repeater functionality. Mode 2 is part of the ETSI standard TS102 658. About dPMR technology Both the FDMA (Frequency Divided Multiple Access) radio protocol employed in dPMR and the other widely adopted protocol, TDMA (Time Divided Multiple Access), deliver a 6.25kHz narrowband channel capability. The key difference between the two protocols is that the FDMA protocol presents 'true, always double capacity' 6.25kHz narrowband spectrum efficiency rather than the 'equivalent' 6.25kHz narrowband achieved by TDMA through creating two 6.25kHz equivalent channels from a 12.5kHz channel when a repeater is used to synchronise the time slots.
dPMR radios employ industry standard DVSI AMBE+2™ vocoders which converts an analogue audio signal to a digital signal while reducing unwanted interference such as background noise and acoustic echo to provide better voice quality and clarity.
Digital modulation protects dPMR radios from being easily monitored by an analogue receiver and an inbuilt 15-bit digital scrambler adds further to the resulting enhanced security.
