IDAS™ Digital Clarity


Intelligible Audio Over a Large Total Communication Area

In conjunctions with the industry standard AMBE+2™ Vocoder and Icom’s DSP expertise, maximum voice clarity and background noise suppression within the 6.25 kHz channel is achieved.

True Narrowband: Reliable Communications for Half the Spectrum


IDAS (both NXDN and dPMR) operate at true 6.25 kHz channel efficiency. Even in urban areas, where users often experience channel congestion, narrowband digital channels offer higher communication access capability. Radio spectrum is a scarce resource and IDAS provides a future-proof solution not only now, but also in many years ahead as 12.5 kHz channels become full over time.

Communications Reliability When You Most Need It

No need to allow for TDMA time slot synchronization. Instant communications in emergencies and critical situations. FDMA is the fail safe mode of choice in land mobile radio. Nothing else compares.

FDMA: Proven History Like No Other Radio Technology

For over 50 years, FDMA has been the backbone of twoway radio communication. Generational enhancements have culminated in the realisation of 6.25 kHz FDMA digital protocols that are literally ahead of their time, while keeping backward compatibility with analogue FM radio.


6.25 kHz Channels: The Current and Future Trend

6.25 kHz channel plans and standards are used in North America, Europe, Japan, Oceania, and the list goes on. 6.25 kHz provides an answer to the worldwide problem of spectrum shortage and efficient use.

6.25 kHz Fundamental Excellence

Narrower bandwidth FDMA provides technical excellence in sensitivity, interference resistance, increased coverage, audio quality, spectrum efficiency and more.


Customizing Audio Quality


IDAS radios also implement audio features and settings to compliment the performance of the vocoder.


Position Data Transmission Capability


When the GPS feature is used, the IDAS radio can automatically transmit accurate position data at programmed intervals. The position data can be sent with voice call or status call and can be used with a third-party AVL (Automatic Vehicle Location) system. The GPS log functions logs user position data in a microSD card memory.


Transparent Data Modem


The IDAS radio can be used as a transparent data modem which transmits the serial data received from a PC or various devices*. The IDAS radio can interface with other Bluetooth® devices for easy data entry.

Emergency Call and Alert


To ensure workers safety, IDAS handheld radios have the following four emergency related functions. If one of these functions are activated, the radio automatically sends an emergency signal.



Remote Monitor (NXDN™)/ Ambience Listening (dPMR™)


A Remote monitor call or Ambience listening call* remotely controls the receive radio to automatically transmit its microphone audio, for the specified timer period. You can remotely activate the radio’s microphone and listen into the environment surrounding the user to help identify if an emergency exists, or what is occurring near the user.
* The Remote monitor call or Ambience listening call can be made from designated IDAS radios.


Radio Kill, Stun and Revive


If a radio is lost or stolen, the radio Kill function disables the radio over the air to reduce any security threat. When the radio Stun command is received, all functions will be temporarily locked out until a Revive command is received or the user password is entered*.
* The radio Kill, Stun and Revive commands can be made from designated IDAS radios.
