Asymmetric Max. Rate Forward 723.2 kb/s or 721 Kb/s ?

On page 41 (Baseband Spec.) It says that "The asynchronous
channel can support maximal 721 kb/s asymetric ( and still be up to 57.6
kb/s in the return direction) "
On page 65 in table 4.10 for packet DH5 it is shown that the Asymmetric
Max. Rate (kb/s) is:
Forward = 723.2 kb/s Reverse = 57.6 kb/s
Which one is correct?
The response is that 723.2kb/s is correct. The DH5 packet may cover up
to five time slot and 266.6 Tx/Rx will be possible.
1600 hops / (5 (Foward) + 1 (Reverse)) = 266.6666
So total data rate for fowarding is as follows:
339byte(Max Payload) * 8bit * 1600 / 6 = 723200 bps = 723.2kb/s |
