Under noisy RF conditions, how would i expect network
throughput to vary as the fragment size is increased
from very short to very long

This is a complex issue. The ITU-R subcommittees
have addressed some aspects, particularly in relation
to the carrier to noise ratio versus bit errors
and block error rates. In the context of asynch
framed bit streams the answer depends on what QAM
constellation you use. However, the re-try rate
for IP based systems, and hence the impact on latency,
I do not believe has been covered. Perhaps you may
know how one relates to the other. Check out the
ITU Radio subcommittees.

Hi lankapala,
When you encounter radio communication
problems, the configuration of the Wlan devices
can be the cause of the radio failure. You must
configure certain parameters properly for the devices
to communicate successfully. If you configure the
parameters incorrectly, the problem that results
appears to be a problem with the radio. These parameters
include the Service Set Identifier, frequency, data
rate, and distance.
