Question 15

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?

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.

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.

Manual identification of radar pulses using spectrum analysis charts can be very difficult due to radar's low amplitude at the Wi-Fi receiver.

Modern spectrum analyzer adapters do not provide the necessary bandwidth resolution required to detect and measure radar signatures.

Question 16

If radar has reportedly been detected on your WLAN deployment, what bands would you consider avoiding?

Response:

5 GHz UNII-2 and 2e

5 GHz UNII-2 and 3

5 GHz UNII-2, 2e, and 3

5 GHz UNII-1 and 2

5 GHz UNII-1, 2, and 3
