I see in LA-RICS board meeting agenda that LASD will be issued 262 portables as part of early deployment testing and usage by specialty units.
Document states the early deployment system would serve as proof of concept including giving LASD encryption capability.
Some of the units to be issued the radios include: LA IMPACT, Aero Bureau, Arson/Explosives, Crisis negotiation teams, multiple detective divisions and also the Avalon patrol station.
I suppose in the coming months we will be hearing various new talkgroups appear on the system.
