DMR Conventional

DMR Conventional

Multiple ECOS-D radios are typically connected together using an IP core network to form a conventional private mobile radio network in accordance with DMR Standard ETSI TS 102 361-1, -2, -3. The conventional private mobile radio network can be set up either as a simulcast network of a cellular network.


The key benefits of a digital conventional DMR private mobile radio network are:

  • Two communication channels are available for each radio channel
  • No manual channel switching necessary when moving between cells
  • A large selection of interoperable terminal devices


Frequency range

4m, 2m and 70cm


Operating mode

The radios can be configured either as a simulcast (master/slave principle) system or as a cellular network (individual Radio GateWay stations (RGW)). When configured as a simulcast network, two communication channels are available with the single radio channel in the overall radio network shown in the example above. In a comparable cellular network four times as many communication channels are available for simultaneous use.



Over the whole area of coverage the following services can be used, provided the appropriate terminal devices are available:

  • Digital voice services, i.e. via DMR (individual call, group call, all call)
  • Digital data services via SDS (short data messages) or IP
  • Analog voice services using existing or DMR terminal devices

By adding further infrastructure components, dispatcher services and telephone call services to simple wired terminal devices or to existing extension telephones can be realized.



Irrespective of the operating mode, the coverage of the trunked mobile radio network can be extended (i.e. through the addition of a further location) or its capacity can be expanded (i.e. by a further radio channel).


The conventional private mobile radio network can be migrated to a trunked mobile radio network at a later time without changing the hardware.
