Question 8

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:

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 9

An amplifier has a 1 dB compression point of 32 dBm and a gain of 20 dB. Which is the highest average input power shown here that would be safe to operate a 24 Mbps 802.11g signal so that spectral regrowth is not a problem?

Response:

Options:

5 dBm

0 dBm

−5 dBm

10 dBm

Question 10

The thermal noise is at −174 dBm/Hz. A spectrum analyzer has a resolution bandwidth of 1 kHz and a 5 dB noise figure. What is the level of the noise floor?

Response:

Options:

−174 dBm

−139 dBm

−144 dBm

−204 dBm

Discussion

Question 11

You have determined the best mounting locations for APs in a given installation. The facilities manager has asked you to change the locations for

several APs due to aesthetic concerns. You suggest mounting the APs in the ideal locations and painting them so they go unnoticed in the

environment.

What is a valid recommendation or consideration when painting APs?

Options:

Always use paints with metallic dye in them to prevent potential RF propagation impact.

Painting APs will significantly reduce the output power.

Painting APs may void the product manufacturer's warranty.

Most AP models for indoor environments come in a variety of form factors and colors. Painting is never recommended.
