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.

6 is almost enough to pass DVD quality A/V streams.

Which is *compressed* !

I need *uncompressed* with guaranteed QoS as Nordic Semi call it. Hence the overhead on
the data rate.
