ve to be authenticated again. This is important to avoid delays for traffic between access points. 802.11 An IEEE networking standard used in mesh networks. It defines how access points access Wi-Fi in community- wide Wi-Fi networks, large homes, and buildings. 802.11 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. 802.11 Improves the ability to manage Wi-Fi networks by enabling statistics gathering and power management that will improve battery life. A must in client devices and access points. 802.11 A standard used for security that protects Wi-Fi devices from attackers with spoofed (fake) addresses. 802.11 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. Contro An IEEE standard for Wi-Fi switches to control access 1 and points by centralizing intelligence in one device, a Provisi controller. www.TechnicalPDF.com oning Wirele Access Points Unlice A way to route cell phone traffic over Wi-Fi networks. The cellular network maintains control of calls SO that it can Mobile bill for traffic. Access Wi-Fi A Wi-Fi standard that enables any device with Wi-Fi Direct 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. Can be used for printing directly from a smartphone to a printer. www.TechnicalPDF.com Glossary 2G (second-generation cellular service) Based on digital access to cellular networks. GSM and CDMA are 2G cellular technologies. 3G (third-generation cellular service) 3G mobile standards specify techniques that are capable of supporting more vo
