Hybrid Coordination Function Controlled Access supports QoS requirements under the 802.11e amendment.
Key Takeaway: Hybrid Coordination Function Controlled Channel Access allows for CFPs to be initiated at almost any time during a CP. This kind of CFP is called a Controlled Access Phase. A CAP is initiated by the AP whenever it wants to send a frame to a station or receive a frame from a station. Hybrid Coordination Function Controlled Access is not limited to per-station queuing and can provide per-session service. It is the most advanced and complex coordination function. HCCA support is not mandatory for 802.11e APs.
