But there are already protocols (DECT I'm looking at you) that design all this stuff in, that can happily share channels and do exactly this sort of thing

Yeah, but start using your DECT phone together with hundreds of people in a stadium or in a dense office.

Well US DECT only has 5 channels (everywhere else it's at least twice as many)

DECT base stations are capable of detecting when two (or more) stations are on the same channel and sharing transmission slots between them.

With 10 channels and 12 full duplex slots/channel you can handle 120 people sitting on top of each other, spread them out a bit and then you can handle many more - probably a small number of hundreds if done right
