Spectrum Analysis
A non-802.11 device such as a microwave oven, bluetooth, or Closed Circuit Television
(CCTV), etc. deteriorates data transmitting/receiving performance because it causes
interference in a wireless LAN environment. As a function that measures surrounding
interference, the spectrum analysis analyzes wireless or Radio Frequency (RF) signals to
resolve interference problem instantly.
7.6.1
Retrieving Spectrum Analysis Data
The spectrum analysis function of APC provides the following data.
Sample report: Wireless capture data converted into Fast Fourier Transform (FFT)
Duty cycle report: Channel utilization rate
Interference report: Interference signal information
The FFT report provides the information of an AP and maximum 13 available channels and
also maximum/minimum values of Received Signal Strength Indicator (RSSI) for each
channel. The duty cycle report provides AP information and affected channel information.
In addition, it provides duty cycle transmission data that indirectly provides channel
utilization rate.
The interference report provides AP information, affected channel, or configuration
information of an interferer and also interference information (RSSI or maximum/minimum
frequency of an interference signal) in real-time.
Configuration using CLI
By using the following command, you can check each data.
