nes methods for switches to quickly hand off sessions between access points SO that users don't have to be authenticated again. This is important to avoid delays for voice on WLANs. 802.11s A proposed IEEE mesh networking standard. It will define how access points forward packets between each other. Envi- sioned for community-wide Wi-Fi networks. 802.11u An IEEE standard that enables automatic interworking between cellular and Wi-Fi networks. A user's mobile device with embedded Wi-Fi with 802.11u can automatically switch to Wi-Fi when it's in a Wi-Fi hotspot that has an agreement with the user's carrier. This is part of the Wi-Fi Alliance initiative known as Hot Spot 2.0 to simplify cellular devices' Wi-Fi access. 802.11v Improves the ability to manage Wi-Fi networks by enabling statistics gathering and power management that will improve battery life. A must in client device and access point. 802.11w A standard used for security that protects Wi-Fi devices from attackers with spoofed (fake) addresses. 802.11x A proposed security standard for authentication and security to prevent unauthorized packets from entering wired LANs from Wi-Fi networks. It's an alternative to creating virtual private networks. Control and Pro- A proposal for WLAN switches to control access points by visioning of Wire- centralizing intelligence in one device, a controller. Will less Access Points be used to standardize roaming between cellular and Wi-Fi (CAPWAP) networks. Unlicensed Mobile A way to route cell phone traffic over Wi-Fi networks. The Access (WMA) cellular network maintains control of calls SO that it can bill for traffic. Mobile and Wi-Fi Networks Table 7-5 (Continued) 802.11 Standard Description Wi-Bro (formerly A Korean version of 802.11e. Wi-Fi Direct A Wi-Fi Alliance standard that enables any device with Wi-Fi Direct software to communicate directly with another device. This allows a laptop to act as an access point SO that nearby computers can also access the Internet. Includes WAP2 security. Can be used for printing,
