In a fragment burst, a fragment that is not the last fragment carries a duration value equal to time it takes to transmit which frames? (Please include appropriate interframe spaces in your answer also).
The newer Dell Wireless adapters allow you to configure RTS Thresholds and Fragmentation thresholds as well. You can do some pretty interesting stuff like testing exactly what Devin is talking about.
I find it is very easy to use a tool like AM Laptop Analyzer to view the duration values as you go through a set of fragments. The second to last duration value drops a bit and then the last duration value drops all the way down to 44 microsecs (assuming the ACK is coming back at 24 Mbps).
I couldn't agree more. How Ben describes learning this is how we teach it in CWAP. Good stuff. Thanks Ben!
