Harris Corporation and Midwest Radio Systems Deploy Simulcast Technology in Countywide Public Safety Application Jefferson County Installs Harris Intraplex SynchroCast(R) System, a Cost-Effective Upgrade for Proven Reliability and Support CINCINNATI, Jan. 18 /PRNewswire-FirstCall/ -- Harris Corporation (NYSE:HRS), in conjunction with Midwest Radio Systems Inc., today announced the sale and installation of Intraplex SynchroCast(R) multiplexers for the Jefferson County Sheriff's department and 911 dispatch located near St. Louis, Missouri. The system is designed to increase coverage and broaden market reach by operating multiple overlapping transmitters on the same frequency. To meet Jefferson County's need for a more reliable infrastructure and support network to serve its dispatch center, Harris was contracted to install its Intraplex multiplexers with SynchroCast at five sites, enabling each with five-channel simultaneous communication with seven site receivers per channel. Jefferson County receives nearly 100,000 calls per year, transmitting to 24 remote fire, police, and EMS agencies. This is made possible by GPS satellites and precision digital timing; signals from five transmitters simulcasting together to eliminate artifacts at the listener's receiver. The Harris Intraplex SynchroCast system allows Jefferson County's dispatch to reach an unprecedented 95 percent of the area. Additionally, it can support future data broadcasting initiatives as the technology supports a voice-data network, eliminating the cost of future base-station, transmitter, or other infrastructure investments.
