What is the size of this IEEE 802.11 MPDU?
Given: An IEEE 802.11 data frame is encrypted with CCMP/AES and is carrying the maximum frame payload. This data frame is being transmitted from a QoS STA to a QoS AP.
What is the size of this IEEE 802.11 MPDU?
where and how would you begin troubleshooting this problem?
As a WLAN consultant, you have been contacted by one of your customers to go to their premises to troubleshoot a problem with a single wireless client station (Station-Z). Your customer informs you that other wireless client stations are not having problems with wireless connectivity, and that Station-Z is configured in the same manner as all other wireless client stations on the network. Station-Z is showing an unusually high retransmission count in its client utilities. Using a wireless protocol analyzer, where and how would you begin troubleshooting this problem?

Which option below describes how the access point will handle this data frame?
Given: An ERP STA transmits a data frame through an autonomous AP destined for a wired station that is connected to a Fast Ethernet switch. The ERP-OFDM modulated data frame carries a 1600 octet MSDU.
Which option below describes how the access point will handle this data frame?
which performance related information element?
Per the IEEE 802.11 standard (as amended), Association and Reassociation Request frames carry which performance related information element?
which of the following explanations would you give to the administrator?
An administrator decides to optimize WLAN performance by adjusting the fragmentation threshold on each access point to a value much lower than the default of 2346 bytes. She notices that when wireless client stations are doing prolonged data transfers from a wired server, that downstream performance is better than it was before her adjustments. One problem she has not yet solved is why performance in the upstream direction has not been improved due to these adjustments. As a wireless protocol analyst, which of the following explanations would you give to the administrator?
