Spectrum Scan Overview

Wireless networks operate in environments with electrical and RF Radio Frequency. RF refers to the electromagnetic wave frequencies within a range of 3 kHz to 300 GHz, including the frequencies used for communications or Radar signals. devices that can interfere with network communications. Microwave Electromagnetic energy with a frequency higher than 1 GHz, corresponding to wavelength shorter than 30 centimeters. ovens, cordless phones, and even adjacent Wi-Fi Wi-Fi is a technology that allows electronic devices to connect to a WLAN network, mainly using the 2.4 GHz and 5 GHz radio bands. Wi-Fi can apply to products that use any 802.11 standard. networks are all potential sources of continuous or intermittent interference.

The spectrum monitor (SM) software modules on Instant APs (IAPs) can examine the RF environment in which the Wi-Fi network is operating, identify interference, and classify its sources. An analysis of the results can then be used to quickly isolate issues associated with packet transmission, channel quality, and traffic congestion caused by contention with other devices operating in the same band Band refers to a specified range of frequencies of electromagnetic radiation. or channel. SMs are IAP radios that gather spectrum data but do not service clients. Each SM scans and analyzes the spectrum band used by the SMs radio (2.4 GHz Gigahertz. or 5 GHz).

The recorded spectrum is not reported to the virtual controller. A spectrum alert is sent to the virtual controller when a non-Wi-Fi interference device is detected.
