@Edent I looked into this just a bit a few years ago; basically there seems to be a constellation of smallish problematic factors which has (so far) precluded commercial efforts into bringing something like this forward. (High power requirements, competing standards, TI sitting on IP, significantly cheaper radio alternatives...)

I did find at the time that there was a hobbyist who had produced small runs of kits using the TI parts. I will poke around Tindie to see whether that person still fits the bill and report back.
