Worcester County Emergency Services Maryland Eastern Shore Interoperability Network (MESIN)

In September 2003 Worcester County was awarded a $5.6 million dollar federal grant to develop an interoperable communications project. After a year and a half MESIN was unveiled at the Maryland Emergency Management Agency’s (MEMA) emergency operations center in Reisterstown . MESIN allows public safety agencies in all nine Maryland Eastern Shore Counties , and Ocean City , to communicate with each other through a M/ACom Network First® system. Field units can switch to a “calling” channel monitored at MEMA and then be assigned one of four “tactical” channels for as long as needed. MEMA and all the county 911 centers on the Shore have the ability to activate and de-activate a series of repeaters in each county to produce the interoperable link.

Future expansion of the system is expected to link MESIN with the Central Maryland Area Regional Communications (CMARC) system. This would allow units in one of the five Central Maryland counties to communicate with Eastern Shore units.
