The NKNOC Labs facility is located 25 miles east of Pittsburgh in Westmoreland County Pennsylvania, which operates its Dept. of Public Safety radio communications over a Motorola APCO-25 Smartnet/Smartzone system.  This countywide system had been years in the making, and is a digital (APCO-25 @ 9600 baud) 800Mhz trunked format.  Implementation of the new system includes the installation of the console radio and CAD electronics at the 911 EOC building located in Hempfield, approximately 26 tower transmission sites throughout the county, as well as the deployment of over 5500 mobile and handheld units across 200 TalkGroups.  District 1 Police (Jeannette, Irwin, Manor, Adamsburg, Trafford, and Penn Twp.) began using their portion of the system on 01 November 2004, with District 9 Police (New Kensington, Arnold, Upper Burrell, Lower Burrell) going live on 20 November 2004 at 12 noon.  In early January 2005, District 4 Police (Ligonier Boro, Ligonier Twp, New Florence, St. Clair, Bolivar, Latrobe, Derry, and Seward) went on the air.  More districts and units have been added since then.  The new 800Mhz system is currently being used by the 9-1-1 Center, Districts 1, 3, 4, 5, 6, 7 and 9 Police and most Fire Departments and EMS Stations within those District boundaries, including Mutual Aid Ambulance Service; all 65 Emergency Management Coordinators and Directors; the Department of Public Safety Administrators; the County Park Police; County Detectives; the County Sheriff’s Department; Adult Probation Bureau; Bureau of Elections; several College Campus and Hospital Security units; County Commissioner's offices; County CIS; the Transit Authority; and County Road and Park Maintenance, along with several other county managed agencies.  Local PA State Police units also have 800Mhz radios that utilize the TRS to provide interoperability communications with county law enforcement.

UPDATE FROM WCDPS- Circa 2006: "The Department of Public Safety is pleased to report that construction of the county-wide 800 MHz system has been completed and that all organizations currently dispatched by the County 911 Center are on the air.  The number of subscriber radios  that have been programmed for operation on the system stands at approximately 4300 units. Over the coming months, the Radio Communications Council and the Department of Public Safety will be working  closely with Motorola and the emergency response community to make the system more robust."
