Organization of Affiliated Secure Interoperable RF Subsystems

The OASIS radio system is regional radio system that consists of two connected zones (One for Waukesha County and one for Milwaukee County). Current users of each county's analog system will be migrating to this digital system within the next next year or so.

Milwaukee County Radio Service's Division is utilizing a 'Smart-X' Zone Controller to help with the transition of users from the current analog system to this digital system. I found a great write up about it which you can read by Clicking Here .

As for Waukesha County users, there are a few users at the moment. It appears that users are going to cut over to the system without the use of patches.

Here are some links related to the system:

Click Here For The Milwaukee County Office of Emergency Management's page of OASIS.
Click Here For the Milwaukee County's "Radio Advisory Council" (RAC). There is some nice (Albeit dated) information regarding the new system.
