PlantCML is a subsidiary EADS and does indeed sell their radio systems for public safety use.
The Richardson system will use EADS CorP25 system components and is a native P25 system. It will be a 4 site trunked simulcast system using 7 or more channels, as opposed to their existing single site/dual voted EDACS system, which is now nearly 20 years old.
The new system will support TDMA (phase 2) but will initially be deployed in C4FM mode (phase 1). It also will have a complete ISSI subsystem, run consoles over CSSI, and support AES encryption. A subset of radios will be encrypted.
All subscriber units (radios) on the system will run the newer half rate AMBE 2+ vocoders. Richardson will be taking full advantage of the ability of the system to support any P25 compliant radio, and will be conducting extensive testing of available units in the near future.
The new network will be fully redundant, with dual system controllers, dual simulcast master units, and dual trunking controllers. All sites are back hauled over Richardson's fiber optic system (10 gigabit core).
Should be pretty sweet.
