Today’s Wi-Fi® networks carry a heavy load of real-time data applications - especially voice and video – which means low tolerance for latency, packet loss, and jitter. Wi-Fi Alliance has several certification programs that enable Wi‑Fi networks to optimize performance by managing the requirements on different types of traffic and ensure the best user experience in home, enterprise, and hotspot environments.
Wi-Fi CERTIFIED WMM
Introduced in 2004, Wi-Fi Alliance added quality of service (QoS) functionality in Wi‑Fi networks. With WMM, network administrators and residential users can assign higher priority to real-time traffic such as voice and video, while assigning other data traffic to either best-effort or background priority levels.
Wi-Fi CERTIFIED WMM-Power Save
Introduced in 2005, WMM-Power Save improves the battery life of mobile devices and increases the efficiency of transmission of voice calls over Wi‑Fi networks.
Wi-Fi CERTIFIED WMM-Admission Control
Introduced in 2012, WMM-Admission Control further improves the performance of Wi‑Fi networks for real-time data such as voice and video. It improves the reliability of applications in progress by preventing oversubscription of bandwidth. WMM-Admission Control accomplished this by enhancing the prioritization of traffic using the access categories introduced by WMM (i.e., voice, video, best effort data, and background data) by using bandwidth management to take into account network load and channel conditions.
