Through an integrated approach, Black & Veatch worked with Baltimore County, Maryland, to combine their existing public safety and public works communications systems. The 800 MHz systems were consolidated into a single P25 trunked system with a new 700 MHz data system, tower sites, 9-1-1 center and dispatch consoles. The system carries all County, some State of Maryland, and some Central Maryland Area Radio Communications (CMARC) public safety traffic. The new system provides improved communications capabilities for all County departments and interoperability with allied agencies in the CMARC area.
As part of the collaborative effort, Black & Veatch conducted a thorough front-end needs assessment and developed system replacement options for the County and system specifications. Enhancements included adding ten additional towers, backup prime sites; a ring-protected microwave network, P25 radios with 800/700 MHz capabilities, and an independent microwave network with interface points to the State of Maryland’s microwave network.
