**Supplemental Information:**
The City of Elgin is submitting this application on behalf of its Police and Fire Departments, which will use the system under the terms of the Starcom21 Subscription Agreement. The system will also be available to other city agencies.
**System Type:**
The new system will be an 8-site 700/800 MHz ASTRO Project 25 Simulcast System with a 9-link Point-to-Point (PTP) microwave backhaul network on the Starcom21 network. It will maintain the required Grade of Service at each site, with 16 dB in-building coverage for public safety agencies. Subscribers will use a mix of mobile and portable radios.
**Intersystem Interoperability:**
The system will interoperate with existing public safety agencies using 800 MHz and UHF/VHF frequencies. Users can communicate via NPSPAC 821 Mutual Aid frequencies, and interoperability with analog channels can be achieved through crosspatch setups.
**Channel Loading Factors:**
Initially, 738 units will use these frequencies, with 409 going to the Police Department and 329 to the Fire Department. The system will also support traffic from other agencies like the Illinois State Police and neighboring counties.
**Coverage Area:**
Contour maps were generated using Motorola’s internal software, Hydra, showing coverage for Elgin and existing STARCOM21 sites in Kane County. Additional frequencies are needed to support the microwave backhaul network and ensure reliable service.
**Implementation Schedule:**
The City plans to deploy all 738 users by October 2013.
No frequencies are planned to be vacated at this time.
