radio_tower.gifThe goal of Oakland County's CLEMIS Public Safety Radio Communication System, called OakWIN, is to enhance citizen and officer safety by transitioning Oakland County public safety voice, data, and paging communications from separate incompatible systems into a cohesive, interoperable system.

This state-of-the-art county-wide, interoperable voice radio communication system for public safety has completed tower installations and now is beginning full implementation.


In the mid-1990s, several emergency situations occurred in which multiple police, fire and EMS agencies needed to communicate with one another. One of the most publicized situations was the shooting by a disgruntled employee at a plant in Wixom, during which many law enforcement agencies had to work together to locate and subdue the gunman, but were hampered because they could not communicate with each other. The public safety agencies in Oakland County use disparate radio frequencies, manufacturers and technologies that do not allow their radios to "talk" to each other.

A committee from the CLEMIS leadership and membership was formed to obtain funding and frequencies for a radio system that would allow them to work independently for day-to-day situations, with the ability to communicate seamlessly during multi-agency emergencies.

Specifications were drafted for a digital 800 MHz system that would provide not only interoperability, but also a high level of capacity and coverage. The Oakland County public safety community identified a need for radio communications that would work not only from the emergency vehicles out-of-doors, but also from hand held radios while inside large buildings.

The CLEMIS voice radio system is designed to meet all of the
requirements identified by the public safety officials of Oakland County.

It is a state-of-the-art digital Voice over Internet Protocol 800 MHz system that will provide both interoperability and sufficient coverage inside of buildings, achieved by deploying thirty-six transmitter sites throughout the county. It will replace or supplement all of the existing disparate radio systems with new equipment, including mobile radios,
hand-held radios, and dispatch center consoles for the participating agencies.

The CLEMIS voice radio project is a complex endeavor. Approximately six thousand law enforcement, fire service, and emergency medical service mobile and portable radios will utilize the system, as well as the dispatch centers and hospitals within Oakland County.


The system is managed by the Radio Oversight Committee, which operates under the CLEMIS Advisory Committee.


"‚ÄčThis new system represents another important step in Oakland County's continuing effort to employ the latest and best technology available for the benefit of our citizens.  Oakland County is considered a leader among local governmental units in the nation when it comes to the implementation of cutting-edge technology."
