You are on site, planning a network at a freight shipping company on a busy harbor. Since the preliminary WLAN design specifies support for the 5 GHz spectrum, you would like to test for radar pulses to determine if DFS channels should be supported at this facility. As a part of your spectral survey with a laptop-based analyzer, you include DFS testing to identify the presence of radar. This is done by manually observing Real-time FFT, Duty Cycle, and Active Devices charts of the spectrum analyzer software.
What potential drawback is present with this DFS test method?

• A.Some sources of 5 GHz radar, such as military ships, are mobile in nature. A longer, automated test setup should be used to identify the presence or absence of radar.
• B.Modern spectrum analyzer adapters do not provide the necessary bandwidth resolution required to detect and measure radar signatures.
• C.Manual identification of radar pulses using spectrum analysis charts can be very difficult due to radar's low amplitude at the Wi-Fi receiver.
• D.Many WLAN products that support DFS channels report several false positives. Ideally, the actual WLAN equipment used in the deployment should be used to test for DFS.

You are testing a VoWLAN deployment, and your communication measurements show a certain amount of lost packets. What would be an acceptable packet error rate value to still provide acceptable call quality?

• A.There should be 0% error in a VoWLAN type of deployment
• B.No more than 1% PER max should be acceptable
• C.No more than 8% PER max should be acceptable
• D.No more than 4% PER max should be acceptable

What is the primary reason for avoiding 160 MHz channels with 802 11 in the 5 GHz band'?

• A.The data rate becomes too high which causes some clients to gam access to the medium and never let it go
• B.The output power requited for 160 MHz channels is more than most regulatory domains allow
• C.No APs exist in production that can implement 160 MHz channels
• D.Only two oi three 160 MHz channels exist in the current frequency allocation, tn some regulatory domains only one exists
