From the July 10, 2013 meeting minutes of the Peoria County
Emergency Telephone System Board (ETSB):
In 2005, the ETSB went out for bid for a Countywide radio system. At
the time, a proposal was submitted for a P25 Digital Radio System by
another vendor at a cost of approximately $30 million dollars. Due to
financial limitations and the competitive bid process, it was decided
that the Open Sky system, for approximately $11.3 million, would suit the
needs of Peoria County. Due to the inability of Peoria County to secure
the number of radio frequencies required for the Open Sky system, and a
clause in the original contract specific to that, the ETSB was able to
negotiate a change in technology with our vendor, Harris Corporation,
from the Open Sky system to a P25 Simulcast Radio System for the same
contract price of $11.3 million. It took much due diligence on the part
of the ETSB, and specifically the ETSB Technical Committee, to negotiate
that contract Change Order. Ultimately, Peoria County is getting a
more sophisticated and dependable radio system for the same contract

January 10, 2011:
LCRA is currently in the process of migrating from its current
Enhanced Digital Access Communications System (EDACS) to a new
"OpenSky" wireless communication system. OpenSky is a Harris
digital radio technology that will be used for LCRA’s next generation
radio system. LCRA’s migration to OpenSky will utilize the 900 MHz
frequencies covered by LCRA’s extended implem entation plan. Both site
infrastructure and terminal radio equipment for LCRA’s existing EDACS
radio system are no longer being manufactured for this aging technology.
Furthermore, support for this older EDACS system is becoming more
difficult as the expertise is being directed toward the newer technology.
Nevertheless, approximately 8200 of LCRA’s internal and external
customers depend on the EDACS system for their daily operations. As such,
LCRA will continue to work with its customers to provide a migration
strategy that is both economically and operationally feasible.
LCRA will continue to operate in the 900 MHz spectrum with OpenSky,
thus allowing the reuse of existing antenna systems, site infrastructure
and available channels. The radio migration is phased in a five year
implementation schedule to allow for the hardware replacement of 56 sites
and adequate testing during each phase. The phased migration is also
necessary for LCRA to coordinate both internal and external resources.
It is essential that LCRA phases its radio migration to allow its
customers to adequately plan their transitions.

Due to benefits related to cost and coverage, Fayette County focused in the past on adopting
the 900 MHz Opensky system as the standard for their emergency responders. After several years,
it has become clear that the lack of interoperability of the 900 MHz system with surrounding P25
compliant systems is causing significant challenges related to intra-county and regional

Radio System Migration – FY 2019 Telecommunications Upgrade – The project will upgrade firmware in approximately

dispatchers. The upgrade is based on vendor recommendations and notifications regarding termination of OpenSky support for
