    Project Map:


    The Pima County Wireless Integrated Network (PCWIN) regional public safety communications system was built to provide interoperable voice communications between multiple public safety agencies and disciplines to improve service delivery and coordination.

    A state-of-the art Motorola Astro25 trunked digital radio system was constructed to provide widespread coverage and radio service across Pima County; in-building coverage is provided where end users specified it.  Communications sites were selected based on their ability to provide the specified coverage and to make best reuse of then existing facilities to minimize visual, cultural, environmental and cost impacts from the project.  Only five new communications sites were constructed.  The radio network also incorporates use of legacy fiber networks provided by the City of Tucson and Pima County.

    PCWIN initially provides communications service for thirty police and fire agencies, eight hospitals, and Pima County’s non-public safety departments.  The initial deployment of equipment included purchase and installation of 7,200 mobile and portable radios and 77 dispatch consoles in eight public safety dispatch centers. 

    The project was managed by an Executive Management Committee (EMC) comprised of public safety officials appointed by the Board of Supervisors.  The participating agencies have signed intergovernmental agreements to support the system and are represented on the PCWIN Board of Directors.
    The PCWIN project has provided communications capabilities never before available to our first responder community.  It is now possible for first responders to interoperate with other first responders, on demand, and in real time to coordinate services and resources when responding to incidents requiring a multi-agency or multi-discipline response.
