Configuration Guide Configuring FSS
SNC Connecting to the AC for Frequency
Spectrum Analysis
Through the interaction between SNC and AP, non-802.11 interference
sources such as microwave ovens, cordless phones, and Bluetooth
devices are recognized in a wireless environment.
4.3.1 SNC Connecting to the AP for Frequency Spectrum Analysis
An AP recognizes non-802.11 interference sources such as microwave ovens, cordless phones, and Bluetooth devices in
a wireless environment and sends them to the SNC software for sort-out and display through the connection channel
established between the AP and the SNC software.
Working Principle
Frequency spectrum analysis is achieved through the interaction and SOCKET connection between SNC and AP. After
FSS is enabled, an AP regularly collects non-802.11 interference information in the RF environment and performs Fast
Fourier Transform (FFT). Then the AP classifies the information for processing, recognizes and sends specific
interference sources to the SNC software via the agreed protocol. After receiving information, the SNC software sorts out
and displays the interference information in various ways. For specific operations, refer to Ruijie's user manual for the
SNC software.
