Digital Vehicular Repeater


The Digital Vehicular Repeater is one of the integrated capabilities of the versatile Catalyst ICETM product.  First Responders can easily enable ICE to rebroadcast land mobile radio traffic from local, low-power radios, to one another and to their home radio system.  Catalyst can configure ICE with a variety of mobile radios including the 50 watt Harris Unity radios shown above.  The Unity is a multi-band P25 radio and ICE can instantly tune it to match the specific scenario to support Radio Frequency Channels from VHF to 800 MHz.

Enable On-Scene Communications

Portable radios are sometimes unable to communicate with the agency's radio towers because portable radios have less powerful transmitters.  When First Responders enter buildings, this limited “talk-back” capability is particularly acute.  In some cases, officials using portable radios are unable to communicate directly with one another in “talk around mode”.  When ICE is deployed at the scene, First Responders can communicate with one another and often with their dispatchers.   ICE receives the low powered signals from portable radios and rebroadcast it to other radios on scene using a higher powered transmitter.  When equipped with at least three mobile radios, ICE can simultaneously rebroadcast the audio to the radio towers so that dispatchers and other first responders off-scene can hear the audio.

Key Features

Key features include support for the predominant frequency bands used for Critical Communications, the ability to allow First Responders to talk with one another and their dispatchers from coverage holes, and the capturing of audio when communicating off the radio network.

VHF, UHF, 700 MHz, & 800 MHz

The ICE Digital Vehicular Repeater leverages the Unity radio’s ability to support hundreds of channels, P25 Talk Groups, and other Land Mobile Radio formats.

Extend Coverage Further

ICE can use high powered mobile radios like the 50 Watt Harris Unity to penetrate buildings and talk back to distant radio towers.  These mobile radios can also detect weaker local signals than portable radios can, extending the talk back range for local First Responders using low powered portable radios.  

Record Local Audio

When First Responders are talking directly to one another rather than using the local towers, the audio typically goes unrecorded.  The ICE Digital Vehicular Repeater records the audio locally and those recordings can be exported a traditional Logging Recorder or replayed on a computer using tools included with the Windows operating system.
