Oklahoma Wireless Information Network (OKWIN)
From The RadioReference Wiki
This system is the compilation of several independent systems across the state. The state of Oklahoma and the cities of Tulsa, Shawnee, Norman, Edmond and Owasso all had separate Morotola trunked systems. These systems have been combined in an effort to form a statewide public safety system. The cities (Tulsa, Shawnee, Norman, Edmond, Owasso) are considered "co-owners" and retain the rights to program their own radios. All other radios are allocated by the Oklahoma Department of Public Safety, which controls the system.
The computer that controls the system is in Tulsa at the Emergency Operations Center.
The system began in Oklahoma City with a 5-channel single-site system on the 300 foot DPS tower at NE 36th and Eastern Ave (a location that is part of the site 8 simulcast system today). This was expanded to a five site system, to cover the Troop A area (Oklahoma, Canadian, Cleveland, Lincoln, Logan, McLain and Pottawatomie Counties) by adding sites in Geary, Crescent, Tecumseh and Lexington. These sites were existing state-owned towers and were inter-connected by 2GHz microwave links.
The City of Tulsa had implemented its own 2-site simulcast system for all city communications. When the Department of Public Safety wanted to include the Tulsa area in the system, they reached an agreement with Tulsa to combine the two systems
The goal for 2006-2008 was to provide coverage for the I-44 corridor, which includes, Tulsa, Oklahoma City and Lawton and therefore a large percentage of the state's population. That phase of the system is complete, with OHP troops in Vinita, Tulsa, Oklahoma City and Lawton all fully operational on this system.
Work is currently (November 2009) underway to include Troop F (Ardmore), which would include the I-35 corridor south from Oklahoma City to the Texas border.
Information on the Tulsa site provided in 2007:
"The Tulsa Site is a 28 channel two-site simulcast sub-system. Tulsa uses Series-2 Plus radio consoles, but will upgrade to the Gold Elite radio consoles. The system uses SmartZone Manager with RDM. On the radio consoles dispatchers can view the decimal ID of the radio PTTS and Emergency Alarms. From the RDM, dispatchers can use the Dynamic Regrouping, Inhibit, Radio Check, Snap Shot and Emergency Alarm Display. With the RDM and SmartZone Manager, a supervisor can determine who Regrouped or Inhibited a given radio and the date and time the command was issued. "
