The IDAS System bridges the gap

Digital/analog mixed mode operation

The IDAS radio can receive both analog mode and digital mode signals on a single channel. You can partially introduce the IDAS radios, while using the existing analog radios in a system. The IDAS system allows you to scale migration to narrow band digital at your own pace and need, while running your existing analog system. It is a cost efficient way to obtain the next generation in two way radio technology, while protecting your current system investment.

Double your channel capacity

The IDAS system doubles the capacity of the current 12.5kHz channel allocation. Icom allows you to meet any narrow banding requirements today, and provides a solution to any future spectrum deficiency now.

Peer-to-peer communication with FDMA

The FDMA enables "peer to peer" communication between subscriber units in narrow band mode. It ensures communication with no reduction in channel capacity, even if a repeater site is not available, or goes down.

Improved audio quality and distance

Better sensitivity and a lower noise floor at the narrower bandwidth plus the latest in vocoding technology mean you have crystal clear audio over a greater coverage area than analog FM as the narrower signal travels further at the same output power.

Network interface*

The IDAS repeater has a network interface*1 and can be connected to a LAN or the Internet via Ethernet cable. Communication range is vastly extended by the Internet connection and eliminates the need for expensive leased lines. When connected to a PC via a LAN or the Internet, you can remotely maintain the repeater configuration from your PC.

Digital trunking*

The repeater will also have digital trunking capability in the near future. This will allow you further effective channel management by sharing a minimum of channels with a large number of users.


*Some features are planned and released in the future.
