Several users are complaining that their VoWiFi phones keep losing connectivity.
The WLAN administrator notices that the frame transmissions of the VoWiFi phones are corrupted when listened to with a protocol analyzer near the access point but are not corrupted when listened to with the protocol analyzer near the VoWiFi phone.
What is the most likely cause of this problem?
- A . RF interference
- B . Multipath
- C . Hidden node
- D . Adjacent channel interference
- E . Mismatched power settings
Which 802.11 amendments provide for throughput of 1 Gbps or higher? (Choose all that apply.)
- A . 802.11aa
- B . 802.11ab
- C . 802.11ac
- D . 802.11ad
- E . 802.11ae
- F . 802.11af
When performing a validation survey for a Multiple Channel Architecture (MCA) system in a multi-tenant building with five floors, what aspect should you, as the surveyor, keep in mind?
- A . The RF interference caused by passing airplanes supporting on-board Wi-Fi should be a prime consideration
- B . The channel reuse pattern should be three dimensional with the RF cell extending coverage of each access point to other floors
- C . The omni-directional antennas of the access points should be oriented parallel to the floor to maximize the coverage pattern across as many floors as possible
- D . The Fresnel Zone is completely blocked between floors so each floor is considered a separate site survey
To reduce airtime consumption and provide for better capacity in the 5 GHz band, which data rates are recommended to be selected as basic rates? (Choose all that apply.)
- A . 6 Mbps
- B . 9 Mbps
- C . 12 Mbps
- D . 18 Mbps
- E . 24 Mbps
ABC Company has a 2.4 and 5 GHz WLAN deployment. DFS functionality is enabled as required by the regulatory domain and APs use DFS channels as long as radar is not detected. Band steering is also enabled to encourage dual-band clients to use frequency bands with more capacity.
Your performance analysis shows that many dual-band VoWiFi client devices will move back and forth between 2.4 and 5 GHz as the users roam throughout the building. All APs have 2.4 and 5 GHz radios enabled with transmit power adjusted to accommodate relatively similar cell sizes. This “band hopping” behavior is viewed by network staff to be undesirable.
What is the most likely cause of the unpredictable client band selection behavior?
- A . Interference from 5 GHz radar sources has increased frame corruption and retries on channels 36- 48.
- B . 5 GHz frequencies offer better RF penetration than 2.4 GHz, but 2.4 GHz offers more voice call capacity and lower latency than 5 GHz.
- C . The voice client does not support DFS, and therefore experiences some 5 GHz coverage holes as it moves through the network.
- D . The client’s band selection algorithm prefers 5 GHz, but band steering behavior usually steers 75- 85% of client devices to 2.4 GHz.
