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 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.

Once their time has passed, they're irrelevant.


Which is why you have a receive buffer and there's latency between transmission and reception.
