Application Scenarios for WLAN QoS
This section describes application scenarios of WLAN QoS
As shown in Figure 5-7, network bandwidth is limited. The device needs to provide differentiated services for services, for example, reducing jitter and latency of voice packets and guaranteeing bandwidth for key services.
By using WMM, voice or video data can preempt wireless channels.
By using priority mapping, high priority data is transmitted first.
By using traffic policing, user rate is limited and network congestion is prevented.
