WLAN Quality of Service (QoS) provides differentiated service for wireless users to satisfy their traffic requirements. WLAN QoS has the following functions:
  1. High-efficiency use of wireless channels: The Wi-Fi multimedia (WMM) standard enables the high-priority users to preempt wireless channels.
  2. Efficient bandwidth use: Priority mapping preferentially transmits the data of high-priority users.
  3. Network congestion prevention: Traffic policing limits users' transmission rate, preventing network congestion.
  4. Differentiated services for different types of packets: The same QoS services are provided for packets that match a specified ACL. In this way, differentiated services are implemented for different types of packets.


Applications have differentiated network requirements. The traditional WLAN is mainly used to transmit data due to its low transmission rate. With development of new WLAN technologies, WLANs have been applied to media, financial, education, and enterprise networks. In addition to data traffic, WLANs can also transmit delay-sensitive multimedia data, such as voice and video. By enforcing QoS policies on a WLAN, the network administrator can properly plan and assign network resources based on service characteristics. The WLAN then provides differentiated access services for applications, meeting customer requirements and improving network use efficiency.
