Bridging the gap between analog and digital
IDAS is Icom's digital land mobile radio system using NXDN™ common air
interface. It has useful calling features including selective calling, status
message, radio, stun/kill/revive and GPS position reporting, etc. The IDAS
system is ideal for business and industry users who are thinking to migrate to a
digital system and hence to future mandated narrow channel spacing.
Five benefits of the IDAS system
- Offers a flexible migration path from analog to digital
- Double your channel capacity
- Improved communication security
- Improved communication security
- Flexible application possibilities
- Improved audio quality
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
two-way radio technology and protect 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 communications 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*
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.
*Option
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 larger number of users.
Secure communication
When secure communication is required, the IDAS system provides a digital
voice scrambler using a 15-bit key (about 32,000 keys) for encryption as
standard. This is added security to the digital modulation/demodulation.
Selective call, group call and talk group ID
The IDAS system allows you to call individual or group users. The radio
automatically sends its own ID number when holding the PTT button. The IDAS
radio memorizes up to 500 of both individual/group ID numbers and alias names in
the table. The alias name or individual/group ID is displayed on the LCD while
receiving a message allowing you to identify who is calling.
Emergency call function
When the emergency button is pushed, the emergency signal will be
automatically sent to the dispatcher or another radio. The man down* and the lone worker functions are available for
automated emergency calls (in digital and analog modes. The remote radio monitor
function allows the dispatcher to turn on the PTT button from a remote location
and transmit anything the microphone hears for a preprogrammed time
period.
*Optional
UT-124R required.
Status message
You can set up to 100 conditions such as "on duty," "at lunch" or "in route"
and send your status to another unit or the dispatch. Also, you can request
another unit to send their status and receive it.
GPS position reporting
When used with the GPS speaker microphone, HM-170GP, for the handheld radio
or an external GPS receiver for the mobile radio, the IDAS radio can send the
current position information to another unit or the dispatch. Simultaneous
status message and GPS data can also be sent. When connected to a PC installed
with a mapping software application, the dispatcher will know the real-time
activity of the fleet members.
Data communication
The IDAS radio allows you 4800bps* data
communication. You can send a data message without an external data modem.
Future third party data applications will provide further features
*Error correction, control
data, etc, will reduce number of bits available for actual data
communication.
Radio stun, kill and revive
The radio stun and kill functions disable a lost or stolen radio over the
air, eliminating security threats from undesired listeners. When the radio
receives the stun command, all functions will be locked out until the revive
command is received. The radio can also send radio stun, kill and revive
commands.
Ran (Radio Access Number) for digital code squelch
The RAN code is the digital equivalent of CTCSS for accessing an IDAS
repeater or digital code squelch function.
Other
- Radio check function allows you to verify if another radio is within the
communication range
- Call log displays the received call history
- Call alert function allows you to send a beep sound instead of a voice call
