Question 7

WLAN QoS is a differentiated service capability provided to meet the different network traffic requirements of wireless users.
What functions can be achieved by using QoS technology in WLAN networks?

A. Differentiated services for different types of services: by matching message information with ACL rules or identifying similar messages through application recognition, providing the same QOS service for similar messages, and realizing differentiated services for different types of services.

B. Fair occupation of wireless channels: Through Airtime scheduling, multiple users on the same radio frequency can occupy the wireless channel in a relatively fair manner in terms of time.

C. Reducing network congestion: Through traffic regulation, the user's sending rate is limited, effectively avoiding data packet loss caused by network congestion.
