apply.) - ANSWER-A. Signal strength
dBi is a measure of what? - ANSWER-B. The signal increase
caused by the antenna

of 10s and 3s? (Choose all that apply.) - ANSWER-A. For every 3
dB of gain (relative), double the absolute power (mW). F. For
every 10 dB of loss (relative), divide the absolute power (mW) by
a factor of 10.

During a site survey in a manufacturing plant, the WLAN engineer
determines that thenoise floor is extremely high because of all the
machinery that is operating in the plant. Theengineer is worried
about a low SNR and poor performance due to the high noise
floor.What is a suggested best practice to deal with this scenario?
- ANSWER-D. Plan for coverage cells with a 5 dB fade margin.
Which value should not be used to compare wireless network
cards manufactured by different WLAN vendors? - ANSWER-D.
