Odd.  I have realworld numbers of gsm calls doing 3.4kB/sec which is about 
27kbps -- that includes the UDP overhead and possibly also the ethernet frame 
overhead (I don't recall whether the 'rate' program strips that or not)

no it really is about 80kbps.  :-)

Since your numbers are about double what everyone else is stating I am 
suspecting that you are counting the traffic in both directions.  gsm is 
about 22kbps in *and* out, and you're getting about 60 which is about double 
my 27kbps number.

and 155kbps is pretty damn close to 2*80kbps.
