As it relates to a spectrum analyzer, complete the following sentence.
The ____________ plot always displays the percentage of time (shown on the Y axis) that the overall RF
power is a certain specified threshold (of amplitude) above the noise floor for a given frequency range
(shown on the X axis).
What is happening on channel 1?
Given: Before installing a Wi-Fi network, ABC Company performed a spectrum analysis looking for
problems. The 2.4 GHz RF spectrum looked like Image-A. After installing an ERP WLAN, ABC Company
performed another spectrum analysis during business hours. The 2.4 GHz RF spectrum then
looked likeImage-B close to an AP on channel 1.
Now the 2.4 GHz RF spectrum looks like Image-C and access points and clients can no longer
communicate on channel 1. What is happening on channel 1?
