third-party solutions to expand your IDAS system.
IDAS 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.
IDAS conventional IP network
An IDAS conventional IP network can extend your communication coverage. It lets you connect dispersed sites and allows
you to communicate like a single site. With an IDAS
conventional IP network system, it is possible to have
radio communications all the way from the basement to the
top floor, all in stable digital audio. Already deployed
LAN cables can be used in an in-building solution.
IDAS Multi-Site Trunking
IDAS MultiTrunk extends Icom's single site trunking system to multiple sites. Although IDAS MultiTrunk
builds on the technology of IDAS Multi-site Conventional, it is a huge leap in capabiltiy. With IDAS
MultiTrunk the advantages of trunking are enabled across many sites separated by great distances
for operations that are large and geographically dispersed.
- Scalable from 1 channel to 30 channels per site, up to 16 sites
- Effective operations with all channels used to transmit voice or data payload,
priority monitoring for emergency interrupt, and polite roaming while conversations are occurring
- All the features of a digital radio, like text, GPS and group/individual calls available in
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.
Peer-to-peer communication with FDMA
When compared to a TDMA (Time Division Multiple Access)
6.25 equivalent system, the FDMA (Frequency Division
Multiple Access) enables "peer to peer" communication
between radios in 6.25kHz digital mode. It ensues
communication with no reduction in channel capacity, even
if a repeater site is not available, or goes down.
As explained, the IDAS system allows you to meet US FCC
narrow banding requirements, and provides a solution to
Digital signal advantage
When comparing digital with analog FM, the audio quality
of analog FM gradually deteriorates with static noise as
the distance increases. On the other hand, the digital
audio provides noise-less, stable audio for longer until
the fringes of the communication range.
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
Selective call, group call and talk group ID
The IDAS system allows you to call individual or group
users. IDAS radios automatically send their own ID number
when the PTT button is held down. IDAS radios memorize up
to 500 of both individual/group ID is displayed on
the LCD while receiving a message allowing you to identify
who is calling.
Talk back function and call mode selection
When the talk back function is enabled, the IDAS radio automatically selects the received talkgroup
or individual ID to reply to the received call, while the talk back timer remains. After the talk back
timer is exceeded, the IDAS radios will set to an initial call mode depending on programming which is
either talkgroup or individual call or retain the previous user call mode selection.
Digital voice scrambler
When secure communication is required, the IDAS system provides a digital voice scrambler using a
15-bit key (about 32,000 codes) as standard. This is added security to the digital modulation/demodulation.
Emergency call function
When the emergency button is pushed, the emergency
signal will be automatically sent to the dispatcher or
another radio. Other emergency features are a man down
feature and a lone worker function, available for automated
emergency calls (in digital and analog modes). A 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.
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.
Radio stun, kill and revive
The radio 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
or the user password is entered. The IDAS 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.
Short data message capability
Short data messages of up to 12 characters may be sent and received between IDAS radios or
from the remote communicator.
Up to 16 IDAS repeaters connection over IP network
With the optional UC-FR5000, up to 16 IDAS repeaters can
be interlinked with each other. An IDAS terminal radio user
can communicate with other IDAS terminal radio users
belonging to the interlinked repeater sites and/or a
virtual dispatch station on the network.
Low bandwidth requirement
By using the AMBE+2™ vocoder compression, an IDAS
conventional IP network requires only about 13kbps
bandwidth per one voice path in theory. It means a DSL
class line is sufficient for the IDAS conventional IP
network. The IDAS conventional IP network. The IDAS
conventional network system requires only one fixed IP
address in a group of networked repeaters. Other repeater
sites can work with dynamically allocated IP addresses when
the IP manager/client mode is enabled through some
restrictions may still be applicable.
Integrated system for clean and simple installation
Icom has made it simple and easy to introduce and install an IDAS conventional
IP network system requires only the UC-FR5000 network controller which can be installed into the
IC-FR5000 series repeater - no control server and no extra rack space is required. In addition, the
repeater and network controller settings can be remotely maintained and monitored over an IP connected PC.
RC-FS10 remote communicator
The remote communicator creates an IP-based virtual radio on a PC and works as a simple dispatch. IDAS
communication features can be used with the remote communicator software. UP to 8 target IDAS repeater
sites * can be programmable in the software. Eight remote communicators can connect
to a single repeater
*The RC-FS10 software can transmit one voice path at a time. One CT-24 is required
for receiving an IDAS repeater site and up to 8 repeater sites can be monitored simultaneously with 8 CT-24s.
- 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 notifies receiving party that a
call is coming with a beep sound and blinking icon
- Base station operation for repeater
- Late entry: IDAS radio can decode the received ID
and show group ID, unit ID or alias name on the display
even when turned on during a conversation.
