- 802.11g -- Similar to 802.11b, but this standard supports signaling rates of up to 54Mbit/sec. It also operates in the heavily used 2.4-GHz ISM band but uses a different radio technology to boost overall throughput. Compatible with older 802.11b.

- 802.11i -- Also sometimes called Wi-Fi Protected Access 2 (WPA 2), 802.11i was ratified in June 2004. WPA 2 supports the 128-bit -and-above Advanced Encryption Standard, along with 802.1x authentication and key management features.

- 802.11k -- Predicted for ratification in mid-2006, the 802.11k Radio Resource Management standard will provide measurement information for access points and switches to make wireless LANs run more efficiently. It may, for example, better distribute traffic loads across access points or allow dynamic adjustments of transmission power to minimize interference.

- 802.11n -- The Standard for Enhancements for Higher Throughput is designed to raise effective WLAN throughput to more than 100Mbit/sec. Final ratification is expected in late 2006.

- 802.11r -- Expected to be ratified in mid to late 2006, the 802.11r Fast Roaming standard will address maintaining connectivity as a user moves from one access point to another. This is especially important in applications that need low latency and high quality-of-service standards such as voice-over-WLAN.
