Puget Sound Emergency Radio Network (PSERN)
The Puget Sound Emergency Radio Network (PSERN) is a voter-approved emergency public safety radio system that will be used for dispatching and communications between fire, law enforcement, and other first responders when it replaces the aging King County Emergency Communications System (KCERCS) in 2022.
PSERN is a simulcast 800MHz trunked radio system, utilizing P25 Phase II digital technology to broadcast via 61 radio sites between over 18,000 public safety portable (hand-held), mobile (vehicle), and control station (desktop) radios, as well as and dispatch center consoles within the service area. The system will provide improved coverage, capacity, and reliability, as well as incorporate limited conventional VHF and UHF interoperability capabilities, primarily in the mountains, for connection to other response agencies, such as search and rescue.
The PSERN Project is developing PSERN (the system) and when complete, the PSERN Operator will maintain and operate the system.
