We are responsible for the installation of mobile radios, mobile data radios, and computer equipment in a variety of King County vehicles, including the fleet driven by the King County Sheriff's Office.

Why emergency radios?

Cellphones inherently lack the reliability that first responders need during emergencies. Most cellphone frequencies are shared with the general public and have a tendency to become bogged down by the volume of calls occurring during major emergencies. Emergency radio channels are dedicated to first responder usage. Additionally, radio provides coverage in areas that cellphones currently do not.

800 MHZ Emergency Radio

The largest system supported by Radio Communication Services (RCS) is the regional 800 MHZ emergency system, which is comprised of owners from King County, City of Seattle, Valley Communications center, and Eastside Public Safety Communications Agency. 

The 800 MHZ emergency radio system consists of 27 transmitter sites, mulitple interconnecting microwave and fiber systems, and multiple public safety dispatch centers. It supports 14,000 users in county and suburban agencies, including: 

  • Police departments
  • Fire stations
  • Emergency Medical Services (EMS)
  • General government functions
  • School districts
  • Water and sewer districts, and more
