Placer County, CA has largely completed the first two phases of its countywide Interoperable Radio Network Project: initial upgrades and funding and infrastructure upgrades and has now begun the final phase: construction, testing, and implementation. Completion of this network is of critical importance to Placer County which covers a geographically diverse area and features many remote communities and mountain canyons where radio waves often do not penetrate effectively. Planning efforts began in 2002 when the Placer County Board of Administrative Services conducted a feasibility study for a possible countywide radio network. This article reviews the three phases of the project and their status: (1) initial upgrades, (2) funding and infrastructure upgrades, and (3) construction. As of today, phase three is expected to take several years from inception to full implementation. The State of California’s goal is for statewide interoperability by 2017.
