So after MPSCS will switch to TDMA (I assume there will be no scanners for that) Livonia will leave their old EDACS and join right?
What about neighboring cities. I always wondered why Livonia wasn't in Western Wayne Mutual system. And what will happen to Wester Wayne Mutual? Will those cities join into MPCSC eventually (or at least link TGs).
For now, the MPSCS will remain a Phase 1 system. Hopefully, by the time they decide to start migrating to TDMA Phase 2 technology, there will be a scanner on the market that can decode this new modulation method. With that said, Livonia will switchover to the MPSCS, and deactivate their old EDACS TRS in the near future. Then the frequencies from the old Livonia TRS will become part of the MPSCS.
The reason Livonia was never a part of the Western Wayne Mutual Aid (WWMA) TRS, was incompatibility of radio technology used by both systems. Currently, the WWMA TRS, is at the end of it's lifespan and needs to be replaced. They are evaluating the best options for them to pursue in upgrading to Project 25 technology.
It is strongly hoped the WWMA will not follow the same direction that Downriver Mutual Aid (DMA) chose in going with a different radio vendor other than Motorola. This will make them an isolated island, rather than being on the same network as the rest of Wayne County, much like the Oakland County OpenSky system that has had the same effect in isolating them from the rest of Michigan. Hopefully, the WWMA will make an announcement shortly on which direction they are going to move in.
