Goals

Establish a network of repeaters that link existing radio communications infrastructures to other agencies.

Use a simple approach to achieving communications interoperability without regard for manufacturer or band.

Establish operational plans based on FEMA ISC (Incident Command System).

Architecture – Basic Equipment12 each conventional 150 MHz repeaters

12 each conventional 800MHz repeaters

JPS voter system

150MHz & 800MHz antennas, combiners, & duplexers

Misc R.F connectors, coax and hardware

Each of six locations will be equipped with two pairs of repeaters.

Each pair will consist of a 150MHz repeater and an 800MHz repeater connected together to function as a single dual band repeater.

The two pairs will consist of one dual band ‘Call-in’ channel and one dual band ‘Tactical’ channel

Operational DesignThe initial incoming call from the first responder would be made on the I-Call channel

The I-Call signal 150MHz or 800MHz will use available microwave channels to terminate at Metrocomm where the signals will be voted for best signal and multicast back to all sites.

The signal will also appear on any participating dispatch center consoles.

The dispatching console operator will determine the appropriate Tactical channel ( I-Tac 1-4) using a coverage chart.

All responding users will be directed to the assigned I-Tac channel, freeing up the I-Call channel for other traffic.

AvailabilityThe system is available to all first responder agencies.

Access to the system is conventional narrow band 150MHz or 800MHz.

Radios from any Manufacture can be used including the new 700MHz/800MHz models

Metro applied for and received a special high power licenses on the 150MHz frequencies. (WPYV858)

Both Metro and North Las Vegas are licensed for the 800MHz frequencies. (WPZR673)

In addition to the 6 fixed locations in each band, we are authorized for a temporary fixed or base station at any unspecified location in Clark county.
