Which of the following does 802.11i NOT address?

The 802.11i standard is specifically designed to enhance the security of wireless LANs by defining improved mechanisms for security protocols, authentication, and encryption. It addresses how data is protected in transit, ensuring that unauthorized access is prevented through robust authentication and encryption methods.

Security protocols, such as WPA2, are central to 802.11i because they help establish secure communications across wireless networks. Similarly, the standard outlines various authentication mechanisms, including those utilizing pre-shared keys and more complex infrastructures based on IEEE 802.1X. Encryption methods like TKIP and AES are also essential parts of 802.11i, providing ways to secure data being transmitted over wireless networks.

Throughput, on the other hand, refers to the rate at which data is successfully transmitted across a network. While improving security can have an indirect effect on performance metrics such as throughput, the primary focus of the 802.11i standard does not include addressing throughput directly. Thus, it is correct to state that 802.11i does not address throughput as part of its objectives.
