Cecil County Communications is reaching its 10th anniversary since installation. The radio system
itself is scheduled for a changeover to the P25 technology (Project 25). Project 25 (P25 or APCO-25)
is a suite of standards for digital radio communications for use by federal, state and local public
safety agencies in North America to enable them to communicate with other agencies and mutual aid
response teams in emergencies. In this regard, P25 fills the same role as the European Terrestrial
Trunked Radio (TETRA) protocol, although not interoperable with it. The current EDACS system
will no longer be supported after 2014. This expenditure is a transformation of the dispatch center
and backup center to P25 ready. It is a first step towards the conversion of the entire system to P25.
Cecil County Communications system is comprised of 1500 user units. The portable, mobile, and
base station radios provide the direct communication betweeen personnel and dispatch. The current
user units are nearing end of life and are original to the system. The replacement P25 units will
provide multi frequency use and incorporate the MdFirst 700 mhz system into Cecil County. This is
of paramount importance to our interoperability with surrounding jurisdications. Cecil County is
surrounded by two states and two Maryland counties all on different radio frequencies
