You told your customer that multipath fading may be mitigated simply by moving one or both of the receiver’s antennas a small amount, usually by one to four wavelengths away from its original position. Your customer is prepared to make the change, but does not know the wavelength for 802.11ac.
What is the approximate wavelength of an 802.11ac radio wave?
Correct Answer:
A

At a university, the WLAN has been successfully deployed for ubiquitous access for faculty, students,
and guests. Many student computer labs are available throughout the campus with wired network connectivity, but there are also a few smaller lab areas and workstations where Ethernet cabling is not available. For student wireless use, the students must authenticate against RADIUS/Active Directory using PEAP. Also, the network administrators at this university would like administrative access to these workstations when they are not in use by students so that the administrators can manage group policies, update OS patches, and perform other routine software maintenance.
What deployment option is available and recommended for both student use and remote administration of these workstations?
Correct Answer:
D
When preparing a floor plan graphic for use in predictive and manual site surveying, what calibration
