The correct answer is A. Many WLAN products that support DFS channels report several false positives. Ideally, the actual B. Some sources of 5 GHz radar, such as military ships, are mobile in nature. A longer, automated test C. Manual identification of radar pulses using spectrum analysis charts can be very difficult due to radar's. See the full explanation below for the reasoning.
Question
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? (Choose 3)
