Explanation
802.11e is the IEEE amendment specifically designed to add Quality of Service (QoS) mechanisms to wireless LANs, introducing traffic prioritization so that time-sensitive data like voice and video gets preferential treatment over regular data traffic. 802.11f is the Inter-Access Point Protocol, which deals with roaming between access points and has nothing to do with QoS. 802.11i addresses security, defining the WPA2 encryption and authentication framework. 802.11n is a high-throughput amendment that uses MIMO antenna technology to increase speed, not QoS management.
Memory tip: Think of the "e" in 802.11e as standing for "Enhanced" service - QoS is all about enhancing the quality of your wireless experience by giving priority traffic the treatment it deserves.
