Question 5
A customer is having issues streaming video over wireless in a few high-density areas of their campus. After further investigation, the administrator has singled out the issue pertains to the clients associated to 802.11b/g only access points. The rest of the campus is covered in 802.11n access points. What is a possible reason for the issue with video streaming on the 802.11b/g access points as opposed to the 802.11n access points?
A. The wireless clients were all transmitting at 802.11b data rates and would have operated properly had they been transmitting and receiving at 802.11g rates.
B. Due to the High-Density environment, there was high-utilization of the wireless spectrum. With 802.11n. the access points are able to aggregate the MSDU and MPDU frames into A-MSDU and A-MPDU frames, utilizing less airtime to transfer data.
C. The wireless controller was denying the client access to the video due to multicast-direct supporting the PHY rate of 48000 that the 802.11b/g client could not handle.
D. The clients could not transmit data at the highest mandatory rate of 54 Mbps due to limitations with 802.11b/g. This data-rate is only possible when transmitting at 802.11n speeds.
