Law enforcement and criminal justice agencies are welcome to participate in the mobile data communications network (MDCN), a system that supports remote access to information available from the Department of Justice (DOJ) through the transaction information for management of enforcement (TIME) system.

Each agency partnering with the State Patrol in using the MDCN must purchase and maintain equipment for the car, called "subscriber equipment." A typical installation includes a data mobile radio and antenna, a radio frequency modem, a ruggedized notebook computer, a docking station and client software.

The following service providers have provided contract pricing for MDCN installation by regions throughout the state. Agencies may choose to utilize these providers or contract with a vendor of their choice:

Below you will find information and forms to allow your participation in the MDCN. Please print these pages, complete the forms, and return them to the address noted on the procedures document. The mobile data terminal PSN assignment request should be sent to the DOJ address on that form.


The Wisconsin Department of Transportation, Division of State Patrol, Bureau of Public Security and Communications, administers and maintains the MDCN network.

Contact Paul Schulz at (608) 235-8346 regarding MDCN.

For any questions on the process or application forms, please contact the Bureau of Public Security and Communications, (608) 267-9763.


The Wisconsin State Patrol operates a statewide VHF analog conventional voice radio communications network. The system consists of a mobile radio, a portable, and a vehicular repeater installed in each squad. There is a base station at each of our tower sites and a dispatch point in each of our regions.

Some troopers have an 800 MHz portable as well to allow them access to county 800 MHz trunked and/or conventional systems. Project 25 standard digital radios are being installed in squads to allow communications with new county digital radio systems. The radios that the Wisconsin State Patrol operate on in the VHF conventional system include frequencies that are used by federal, county and municipal agencies. The mobile and portable radios also contain the statewide mutual aid channels available for use by all public safety agencies.

The statewide radio network includes the Police Interagency (POINT), Wisconsin Police Emergency Radio Network (WISPERN), and Mutual Aid Radio Channel (MARC) channels. The Wisconsin State Patrol is a participant in the Wisconsin Interoperable System for Communications (WISCOM) statewide Project 25 digital VHF trunking system project.
