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?

What must occur before a STA operating in an HR-DSSS BSS can transmit a frame over the wireless medium?

The IEEE 802.11 TSPEC element contains which parameters?

What is the duration of the Slot Time specified by the IEEE 802.11 standard for the Clause 17 (OFDM) PHY?

Laptop-1 transmits an MPDU using three addresses in the MAC header. Choose the correct statement.

Given: ABC Company has implemented a WPA2 and WMM capable wVoIP network and wishes to measure quantified voice quality over the wireless medium (WM).

Using a voice-enabled IEEE 802.11 protocol analyzer, how can quantified voice quality over the WM be measured on this network?

A QoS STA is permitted to send which frame types to a Hybrid Coordinator?

What PLCP preamble type does the IEEE 802.11 standard, Clause 17 (OFDM) specify?

To effect Preauthentication, a STA’s supplicant sends an IEEE 802.1X/EAPoL Start message. How is the EAPoL Start message addressed?

According to the IEEE 802.11 standard (as amended), local maximum transmit power for the current channel is regulated by what elements in Beacon management frames?
