Hi I am writing a paper on wimax delay. For some reason, the packet delay in 
Wimax NIST comes to around 200-400 ms with a 20 ms frame even when utilization 
is kept much lower (30%) than capacity.  That's like  10-20 frames just to 
transmit.  It should take only take 3 frames at this utilization (1 frame for 
backoff ,  1-2 frame in transmission queue, and let's say 1 more to receive, so 
delay should be only 30-40ms).  Can anyone thiink what's going on with this 
wimax module. I have formulated the model can't verify it using sim/ulation
