The City of Chicago has been working to modernize our land mobile radio communications. Our goals are to improve efficient use of our existing channels, consolidate disparate systems, enhance security, and plan for T-Band migration.

This project has been undertaken for three specific reasons: 1.) to bring together several disparate systems; 2.) to combat the amount of unauthorized transmissions on our current channels; and 3.) to provide a path for our transition from the T-Band as mandated by the Federal government.

An opportunity existed for the City of Chicago to repurpose 800MHz channels that have been used for our Computer Aided Dispatch (CAD) system because of advances in data communications, the use of private public partnerships, and the potential adoption of FirstNet. We are repurposing our existing data channels and combine them with our existing 800MHz trunked voice channels. Our goal has been to consolidate five different trunked systems in the city into one interoperable network.

We are in process of a multi-phased plan for slow growth over five years (two of which are complete), but with tangible benefits at the end of each phase. Our first step was to consolidate the existing trunked systems and channels. We also integrated Chicago Midway International Airport’s system. Midway previously used T-Band frequencies as their primary system and they have now transitioned over to 800MHz. We are integrating with the City of Chicago’s Department of Water Management (DWM) to provide enhanced coverage within their critical infrastructure.

Our first phase consisted of 13 simulcast sites (8 Tx/Rx and 5 Rx only) with 6 channels, an ASR at Midway, and two separate conventional in-building systems at the DWM filtration plants.

Justification for an Extended Implementation Period (updated March 2020)

The Office of Emergency Management and Communications of the City of Chicago respectfully requests an extended implementation period of three (3) additional years for constructing and placing all the granted frequencies in callsigns WRCT668 and WRCT669 in operation. This would bring us in line with our slow growth plan that was approved for callsigns WQZR532 and WQZR533.
