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
