Hello Patrick,
With all due respect I don't think anyone here doubts the Alvarion VL is not
simply a plain vanilla CSMA product. However, unfortunately the end result

Mark,
...also, in terms of your question about packet aggregation
Marlon,

This is a bit misleading and doesn't answer Marlon's question.
Entering a 0 value in the VL contention window algorithm setting
