Chapter 9 Tools
Spectrum Analysis
Spectrum Analysis can help you to choose the proper channel/frequency. Through the spectrum analysis
you can learn the distribution of the radio noise and intelligently select the channel/frequency in low noise.
1.
Click
Spectrum Analysis
in the tools’ drop-down list, the following window will pop up to remind
you that all wireless connections will be lost during spectrum analysis. Click
Yes
and you will then get
into Spectrum Analysis page.
2.
Click
Start
, the PharOS will begin to analyze the power of frequency. Observe the curves for a period
of time, and then click
stop
. Note that the relatively low and continuous part of the average curve
indicates less radio noise. Here we take the figure below as an example.
NOTE:
CPE510/CPE520/BS510 has a select box of
Frequency Range
at the top-left corner. Select the required range
and then click
Start
.
3.
When choosing channel/frequency, we should try to avoid the spectrum with large radio noise. In this
example, the recommended channel/frequency is 1/2412MHz and 6/2437MHz.
