IDAS system features

Spectrum efficiency

The IDAS™ system utilizes 6.25/12.5kHz narrowband FDMA technology.
This system is not only spectrum efficient but meets the FCC 2013 deadline for narrow band compliance.

NXDN™ Type-C & Type-D Trunking

IDAS™ trunking conforms with the NXDN™ Type-C or Type-D trunking protocols. Type-C trunking is centralized control channel trunking. Type-D trunking is a distributed system which does not use a dedicated control channel.


Audio quality and coverage

Analog vs Digital Coverage
Image Zoom

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.


Flexible IP Network

IDAS™ repeater sites can be interlinked over an IP Network, and can extend your communication coverage. When used with a VE-PG3, VoIP Gateway, the IDAS™ radios* can be integrated into the SIP and analog phone system and interconnects telephone calls.

*Type-D multi-site trunking and conventional using the IC-FR5000 series.


Secure conversation

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


Flexible migration path

The IDAS™ system allows you to scale migration to narrow band digital at your own pace and needs, while running your existing analog system. As your future communication needs change, the IDAS™ system can grow to a trunking system and/or wide area (multi-site) system.
