A. 802.11 securitycompliance

B. Aesthetic requirements

C. Reduce transient RF interference

D. Physical security and theft prevention

E. Protection from environmental conditions

A. Enters a low-power radio state until it receives a WMM PS-Poll frame from the AP

B. Experiences higher throughput and lower latency than when operating in Active mode

C. Buffers frames destined to the low-power AP until the AP wakes its radio and begins beaconing again

D. Alternates between awake and dozing, depending on its need to transmit and receive information

A. Grid antennas ateach endpoint

B. A Fresnel Zone that is at least 60% clear of obstructions

C. Minimum output power level of 2 W

D. A minimum antenna gain of 11 dBi at both endpoints

A. Each AP checks with the DHCP server to see if it can respond and then acts accordingly.

B. After waiting a SIFS, a designated AP sends an ACK, and then replies with a probe response.

C. Each AP responds in turn after preparing a probe response and winning contention.

D. After waiting a SIFS, all APs reply at the same time witha probe response.

E. For each probe request frame, only one AP may reply with a probe response.

A. 10 dBm

B. 13 dBm

C. 20 dBm

D. 30 dBm

E. 26 dBm

A. A facility map with an explanation of applications used in each area

B. I-Beam mounting kits for hanging temporary access points

C. Low-gain omni antennas for APsmounted high on warehouse ceilings

D. Predictive site survey software that supports highly directional antennas

A. Modulation and Coding Selection

B. Dynamic Rate Switching

C. Multirate Control

D. Rate Set Selectivity

A. 75 and 125 ohms are the typical impedances of 802.11 WLAN connectors.

B. Every RF connector causes insertion loss.

C. Large diameter RF cables cause greater loss than smalldiameter cables.

D. Two RF connectors of the same type (e.g. SMA), manufactured by different companies, may vary in specifications.

E. RF cables have upper and lower frequency range specifications.

A. Excessive use of null data frames.

B. Duration values vary widely in each data frame.

C. Use of frame fragmentation with fragment bursts.

D. High retransmission count for a subset of client stations.

E. Increase in downlink (transmitted by AP) frame retries.

A. The Fresnel Zone is completely blocked between floors so each floor is considered a separate site survey.

B. The RF interference caused by passing airplanes supporting on-board Wi-Fi should be a prime consideration.

C. The channel reuse pattern should be three dimensional with the RF cell extending coverage of each access point to other floors.

D. The omni-directional antennas of the access points should beoriented parallel to the floor to maximize the coverage pattern across as many floors as possible.
