When deploying an Enterprise-class VoWLAN infrastructure, which Access Category (AC) must be used to prioritize...

In Wi-Fi networks, the IEEE 802.11e amendment introduces Quality of Service (QoS) features, allowing traffic to be categorized into different Access Categories (ACs) to prioritize data transmission. For Voice over WLAN (VoWLAN) applications, it is crucial to prioritize voice traffic to ensure low latency and jitter. The AC_VO (Voice Access Category) is designated for this purpose, providing the highest priority over other traffic types.

Implementing AC_VO ensures that voice packets are transmitted with minimal delay, which is essential for maintaining call quality in enterprise environments.
