Audio quality and coverage
When compared to an analog FM signal, digital easily outperforms analog in audio clarity at the fringes of the communication range, thus providing more reliable audio over a greater total area, even if the coverage footprint is the same as analog FM.

Secure conversation
The digital modulation/demodulation makes it difficult to decode the IDAS™ digital signal by using the current scanner receivers at this time. The digital voice scrambler adds security on your conversation.

Spectrum efficiency
The IDAS™ system utilizes 6.25kHz narrowband FDMA technology.

IP network connectivity
Since the FDMA protocol systems use digital signals, these can be easily converted and transferred to an IP network or IP based applications. This means an increase in communication coverage.


Icom’s digital land mobile radio system using the NXDN™ common air interface. IDAS NXDN™ offers a complete system of handheld radios, mobile radios, repeaters, network interface/trunking controller, remote communicator, system manager software and various accessories. NXDN™ is a complete digital solution that system owners or operators can grow into as their time and budgets allow.

Complete solution for all markets
While primarily targeted as a solution for business and industry market segments, the acceptance of NXDN™ worldwide has now reached a level where virtually all market segments including public safety entities are using NXDN™. Basically you can dived IDAS NXDN™ by:

  • Conventional peer-to-peer and via repeater
  • Multi Site Conventional (over IP network)
  • Single & Multi Site Trunking (type-D: No dedicated control channel type).

Icom’s NXDN product line-up:

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.

Flexible migration and upgrade path

The dPMR system allows you to scale migration to a digital system at your own pace and needs, while running your existing system. If the radio users increase in the future, or you require expanded communication coverage, the dPMR conventional system can be upgraded to a multi-site system, or grow into a Mode 3 trunking system while using the same subscribers*. This provides investment protection for your communication system.
* Depending on radio model/firmware revision.
