Performance Optimization Window
Wireless performance optimization is useful to enhance the quality of wireless service for users. The
performance optimization includes Background Scanning, Band Steering, Load Balance, RSSI Threshold,
Roaming RSSI, Voice and Video Awareness, and Airtime Fairness, illustrated in Figure 4-32.

Background Scanning: Wireless networks operate in environments with electrical and radio frequency
devices that can interfere with network communications. Microwave ovens, cordless phones, and even
adjacent Wi-Fi networks are all potential sources of continuous or intermittent interference. The
background scanning is able to examine the radio frequency (RF) environment in which the Wi-Fi network is
operating, identify interference and classify its sources.
Background scanning is the basis for some advanced features such as: wIDS/wIPS, RDA (ACS/APC) etc. When
it’s turned OFF, the foreign AP detection and rogue suppression will stop and the RDA will drop its
precision. By default, background scanning is enabled.
The scanning channel can be defined on demand: For highly sensitive packet delay use case, suggest
enabling background scanning only for the working channel. The scanning interval of Background Scanning
can be configured from 5 seconds to 3 hours (180 minutes) according to deployment requirement. For
highly sensitive packet delay use case, it is recommended to prolong the interval from default 20-second
setting. If the interval is longer than 1 minutes, RDA and wIPS feature accuracy will be impacted.
Band Steering: Band steering supports Prefer 5GHz and Force 5G.
Prefer 5GHz feature assigns the dual band clients to the 5 GHz band prior to the 2.4G band. Thus can
reduce co-channel interference and increase available bandwidth for clients, because there are more
