That's the raw data rate only !

Now you have to add overhead for the frequency hopping stuff,
handshaking, whatever

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 don't have to use TCP/IP, and you don't need, or even want, lost
packet redundancy, at least not for streaming audio. If you need a
protocol at all, use something like UUCP.

If you don't account for lost packets what's going to happen to any lost
audio data ? I'll
ask some more next time I talk to the guys about the protocol they're
using.

You get a 'pfsst' noise (that may lose something in translation) until
everything sync's up again. Audio streaming isn't generally critical stuff
so why bother trying to make up the lost stuff.
