The correct answer is C. Manual identification of radar pulses using spectrum analysis charts can be very difficult due to. 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?
Options
- AMany WLAN products that support DFS channels report several false positives. Ideally, the actual
- BSome sources of 5 GHz radar, such as military ships, are mobile in nature. A longer, automated
- CManual identification of radar pulses using spectrum analysis charts can be very difficult due to
- DModern spectrum analyzer adapters do not provide the necessary bandwidth resolution required
