Do you require two-way communication to the (10x10 cm) device, or is it
receive only?
Security: See "rolling code" algorithms, e.g.:

Other security methods may be superior. The most reliable ones need
2-way communication.

Is the voice arbitrary or can it be a pre-recorded message? This may
ease the agency aproval task.

What is the annual volume? Maybe you could interest someone in a
speculative R&D project.

Perhaps for your demo you could use one of the jtech units.

We need one-way communication only.

Yes, I am familiar with the jtech units. They do pretty much
everything except the real time audio. The audio needs to be
transmitted from the server. I believe the jtechs do have an option to
play an internally stored audio message. But, unfortunately, we need a
larger repertiore of sound bites, selectable in real time from the base
station/server. Still, I should probably go back and reconsider just
what I might do with the Jtechs.

Would a rolling code algorithm be compatible with controlling a large
number of these acting in unison?

The volume could end up being in the tens of thousands. And yes, we're
planning to pitch to a third party who might take this on out of
self-interest.

Thanks,
Steve
