Overview of Spectrum Analysis

Overview of Spectrum Analysis


In spectrum analysis, the WLAN device detects different types of interference resources on wireless networks, and the spectrum analysis server analyzes the characteristics of collected wireless signals to identify and locate non-Wi-Fi devices, eliminating the impact of interference on WLANs.


802.11 wireless technology has been widely used on home networks, SOHOs, and enterprise networks. Users can easily access the Internet over WLANs. The 802.11 wireless technology uses public spectrum resources which are also used by Bluetooth devices, cordless phones, and many other wireless devices. Therefore, severe wireless signal conflict and interference occur on wireless networks, resulting in poor user experience.

Spectrum analysis allows WLAN devices to identify and display the interference resources, helping users locate the interference sources to eliminate interference and improve user experience.
