The correct answer is D. In locations with line-of-sight to client devices and little multipath, the benefits of MIMO may be less. See the full explanation below for the reasoning.
Question
Given: ABC Hospital is planning a Wi-Fi infrastructure upgrade where the 802.11b/g APs would be replaced with new dual-radio HT (802.11n) APs. ABC wants to minimize the time and cost associated with performing a new site survey, so they will be mounting all of the new APs in the same locations and with the same cable drops as the existing APs. What is one performance drawback with this deployment method?
Options
- AMultipath will increase, causing excessive layer-2 retransmissions. The retransmissions will cause latency
- BIncreased receiver sensitivity on the HT APs will cause them to continually change channels to avoid
- CIf the existing UTP cabling is not Category 6 or better, the total Ethernet backhaul for each AP will be limited
- DIn locations with line-of-sight to client devices and little multipath, the benefits of MIMO may be less
