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).
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?
Given: ABC Company recorded the 2.4 GHz band with a spectrum analyzer prior to installing their ERP
WLAN. Image-A is how the band appeared prior to the WLAN installation. Image-B is how the bandappears now, and all channels on their WLAN have ceased to function.
What is the best explanation as to why their WLAN is no longer functioning properly?
Your wireless network troubleshooting kit includes an antenna with the following specifications:
Gain: 5 dBi
Azimuth Beamwidth: 55 degrees
Elevation Beamwidth: 50 degrees
Frequency Range: 2.4 – 2.5 GHz and 4.9 – 5.9 GHz
Impedance: 50 Ohms
For what aspect of network troubleshooting would this antenna be most useful?
