What VoWiFi implementations frequently require multicast packet delivery support by the WLAN infrastructure?

• A.Push-to-Talk VoWiFi phones
• B.All VoWiFi implementations
• C.All VoWiFi soft phones
• D.All VoWiFi hard phones

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 4% PER max should be acceptable
• D.No more than 8% PER max should be acceptable

What kind of antenna results in a nearly circular pattern on the azimuth chart but a very flat donut shape on the elevation chart?

• A.20 degree vertical yagi
• B.60 degree horizontal patch
• C.High gain omni-directional
• D.120 degree horizontal sector

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.Modern spectrum analyzer adapters do not provide the necessary bandwidth resolution required to detect and measure radar signatures.
• B.Manual identification of radar pulses using spectrum analysis charts can be very difficult due to radar's low amplitude at the Wi-Fi receiver.
• C.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.
• 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.

Of the following antenna connector types, which one is the smallest?

• A.MC Connector
• B.Male N Connector
• C.RP-TNC
• D.N Connector
