Something similar to wireless computer networking...

Currently only at mp3 like quality. True16 bit linear pcm in
stereo @ 44kHz sampling requires something like about 6 Mbps
of bandwidth.

44,1000 ksamples/sec * 16 bits/sample * 2 channels = 1,411,200 bits/sec

Sorry, that's:

44,1000 samples/sec * 16 bits/sample * 2 channels = 1,411,200 bits/sec

or

44.1 ksamples/sec * 16 bits/sample * 2 channels = 1,411,200 bits/sec

In any case, it's 1.4 Mbits/sec, NOT 6 Mbits/sec.

That's the raw data rate only !

Now you have to add overhead for the frequency hopping stuff, handshaking,
whatever
and redundancy for lost packets - and I've no idea how the data's encapsulated
-
there'll doubtless be extra stuff there too. I'm not calculating this myself,
I have
it on good authority from some guys who are developing the product. I was
quite
surprised how much overhead is required myself actually.

You've provided other BS swearing about the correctness of it and have been
wrong. Your credibility slipped before this and stating 6 Mbit/s here
confirms you don't know Jack.
