Comtech Wireless Communication Case Studies

2-Way Radio Case Studies

Yolo Emergency Communications Agency chooses ComTech for upgradeYolo Emergency Communications Agency
(YECA) is a consolidated 911 Public Safety Answering Point (PSAP) in Yola County, California, providing dispatch services for police, fire, animal control, public works and other local government agencies in the Cities of West Sacramento, Woodland and Winters California. YECA utilized three Gold Fire receivers within the Woodland City limits and nine Green Fire receivers across the county to support in-bound communications, from field personnel to dispatch. In 2011, YECA selected ComTech Communications to upgrade its Gold and Green Fire cutovers to new voting comparators. The project also led to uncovering years of poor wiring, incorrect programming, and layers of setting levels that affected audio outputs.

For Green Fire, dispatch is now transmitting simultaneously from four transmitter sites utilizing simulcast technology. Between the new voting comparators and the additional receiver and transmitter sites, the radio signal is stronger and clearer for inbound and outbound transmissions, including portables, mobiles and dispatch. In addition audio levels for the receivers and for the station alert toning are now uniform and to equipment manufacturer specifications.
