Rolling up developments in Wi-Fi

802.11u also provides key technology that enables the Wi-Fi Alliance Passpoint certification program (a.k.a. Hotspot 2.0). This program allows for the seamless transition of Wi-Fi clients between any hotspot AP that is certified to be Passpoint compliant, eliminating many of the complexities that exist today in discovering and connecting to both public and carrier-sponsored hot spots. Look for 802.11u, and Passpoint compliant, hardware to be hitting the market very soon. [Also see: "802.11u and Hotspot 2.0 promise Wi-Fi users a cellular-like experience"]

* 802.11v: Wireless Network Management (February 2011). 802.11v provides a mechanism for wireless clients to share information about the WLAN environment with each other and APs to improve WLAN network performance in real time. This specification is relatively new, and manufacturers are just beginning to take advantage of some of its features. As WLANs become even more heavily utilized, the benefits of 802.11v will certainly become obvious.

* 802.11w: Protected Management Frames (September 2009). 802.11w specifies methods to increase the security of 802.11 management frames. Management frames are 802.11 packets that control communication on the WLAN, but do not contain data. Currently, management frames are sent "in the clear." This makes them potentially vulnerable to malicious manipulation and can lead to a wide variety of WLAN attacks, from client spoofing (a rogue pretending to be an approved user) to hijacking of all data destined for one or more APs. 802.11w will significantly reduce these risks.
