Icom dPMR Mode 3
Digital Trunking System
The Icom radio dPMR Mode 3 is aimed at businesses and organisations who are looking for a fully networked multi-site trunking system. This may be as a new system or as a replacement of an old MPT system.
Combining Icom dPMR radios with Fylde Micro’s controller, MultiLingo, the Mode 3 system can range in size from a single site up to 16 site trunking operation.
The Icom/Fylde solution is unique in the fact that it can offer an immediate migration path from MPT to dPMR without the requirement of any MPT operation in the IDAS terminals.
The Fylde controller has the ability to encode/decode analogue MPT signals to digital dPMR and vice versa. This avoids the considerable expense of requiring a parallel infrastructure set up to allow an MPT and dPMR digital system to work together.
What is dPMR™?
dPMR is a 6.25 kHz FDMA based digital radio protocol described in the ETSI technical standards TS 102 490 and TS 102 658.
The TS 102 490 standard defines dPMR 446 license-free radio and the TS 102 658 defines Mode 1 peer-to-peer mode, Mode 2 repeater mode and Mode 3 digital trunking.
dPMR is specifically targeting highly functional solutions by using lower cost and less complex technology. Details of the dPMR protocol can be found on the dPMR Association website: www.dpmr-mou.org
dPMR™ Mode 3 Digital Trunking
In an Icom dPMR Mode 3 digital trunking system, a small number of communication channels are automatically and dynamically allocated to accommodate a large number of subscribers.
The trunking sites can be interconnected over an IP network, so the system can be expanded from a single site system to virtually nationwide networks.
The MultiLingo™ trunked radio system controller is provided by Fylde Micro. The MultiLingo™ can be used with the Icom IC-FR5100/FR6100 repeaters.
For smaller systems up to 4 sites, no other control servers are required. Larger systems use Regional Control Servers to manage IP traffic and ensure optimum fixed-link performance.
