A. Identifying problems with Fresnel zone clearance in long range (10+ miles / 16+ km) point-topoint links

B. Matching transmit and receive capabilities for most client stations to reproduce client reception issues

C. Finding the physical location of an interfering transmitter to identify and remove the source

D. Capturing BSS-wide CRC error and retry statistics in most indoor WLAN environments

E. Increasing resolution bandwidth (RBW) on a spectrum analyzer to improve signature identification features

A. The RA field of ACK frames is always obtained from the Address 2 field in the corresponding frame being acknowledged.

B. A client station's Reassociation Request frames are only acknowledged with a Reassociation Response from the access point and not with an ACK frame.

C. In an EDCA BSS, encrypted Data frames are only acknowledged by client stations, never by access points.

D. Following non-QoS Data frames with the More Fragments bit set to 1, the Duration/ID field of the ACK frame is set to a value equal to two SIFS plus the next Data fragment and its ACK.

E. Data frame fragments are acknowledged individually (with an ACK frame).

F. Probe request acknowledgement (sending of a Probe Response frame) is configurable in the access point and is always linked to SSID broadcast configuration in Beacons.

A. The MPDU frame's FCS field is 4 bytes, while the MMPDU frame's FCS field is 8 bytes.

B. The MPDU header always places the BSSID in the first address field, but in the MMPDU the BSSID can be found in any of the address fields.

C. An MMPDU header may only contain three address fields, but an MPDU may have four address fields.

D. Both the MPDU and MMPDU have a QoS Control (QC) field, but all bits of the MMPDU's QC field are always 0.

E. The MMPDU frame body is limited to 300 bytes, whereas the MPDU frame body can carry up to 2304 bytes.

A. Basic rates are optional data rates for the BSS, often used for assuring connectivity for legacy stations.

B. Basic rates are defined in an AP's service set to specify mandatory data rates for all retry frames.

C. The highest data rate set to Basic is automatically used to send broadcast traffic such as Beacon frames.

D. Basic rates are only used for multicast traffic, and do not affect unicast traffic.

E. The AP requires all client stations to support Basic rates in order to associate to its BSS.
