A wireless engineer from your company performed a site survey in an office building where a wireless
network extension was needed. He reports that while performing a Layer 1 sweep near a meeting room full
of people, he detected the RF environment displayed in the exhibit. He is unsure how to interpret what he
recorded to determine its impact on a future Wi-Fi network.

What is true about this RF environment and its potential impact on the WLAN?

While configuring your site survey software for an upcoming manual survey project, you notice the
configuration option for “Network Card Simu-lation” as shown in the exhibit.

What is the purpose of this feature and when would you use it?

When preparing a floor plan graphic for use in predictive and manual site surveying, what calibration
method will lead to the most accurate and reliable RF data?

What exhibit reflects the recommended life-cycle steps for successfully designing and deploying an
enterprise WLAN from start to finish? (Choose 2)

When performing an indoor predictive site survey to make the WLAN planning and design cycle more
efficient, what is a best practice for configuration of the simulated APs in the predictive modeling software?

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)

Assuming an identical RF environment,

which one of these scenarios is most likely to lead to a client-to-AP link imbalance in which one- way
communication results?

Assume that your network operates in a regulatory domain that allows use of UNII-1, UNII-2, UNII- 2e,
UNII-3, and the 5.8 GHz ISM band for indoor Wi-Fi. In your upcoming 802.11n deployment, you would like
to take advantage of the performance improvements that result from channel bonding. However, after
extensive testing, you have determined that your mission-critical WLAN should not use channels requiring
DFS support.
Given those two criteria (enable channel bonding and disable DFS channels), in the 5 GHz spectrum, how
many non-overlapping channels will your system be able to use?

What is a valid 40 MHz channel configuration in the 2.4 GHz ISM band where channels 1-11 are permitted?

You told your customer that multipath fading may be mitigated simply by moving one or both of the
receiver’s antennas a little bit, usually by one to four wavelengths away from its original position. Your
customer is prepared to make the change, but does not know the wavelength for 802.11a.
What is the approximate wavelength of an 802.11a radio wave?
