Explanation

802.11i is the IEEE amendment specifically designed to address security vulnerabilities in wireless networks, introducing WPA2 and the robust security network (RSN) framework, including AES-based encryption and 802.1X authentication. 802.11b and 802.11a are both physical layer amendments focused on transmission speeds and frequency bands (2.4 GHz/11 Mbps and 5 GHz/54 Mbps, respectively), with no security enhancements. 802.11e is a QoS amendment that improves multimedia and voice traffic prioritization, also unrelated to security.

Memory tip: The letter "i" in 802.11i stands for "identity protection" or think "i" = "integrity/security" - it's the one that locks down your wireless network.
