networks. Will be used mainly with the 802.11a protocol. 802.11af Super A proposed Wi-Fi standard designed to operate in the white Wi-Fi space 700MHz spectrum freed up by TV broadcasters. It is envisioned as providing Internet access in rural areas because it can cover large areas. 802.11d A standard that supports the capability for Wi-Fi devices to operate in different countries that require different power levels and frequencies. Enables equipment to be adjusted according to the rules of each country. 802.11e A Quality of Service (QoS) standard, the Wi-Fi Multimedia (WMM) section of 802.11e that defines prioritizing voice and video. Was approved October 2004. 802.11f A standard that supports the capability for access points from different manufacturers to interoperate in the same Wireless Local Area Network (WLAN). 802.11h A proposal that defines ways for 802.11a networks to dynamically assign packets to other channels if there is inter- ference with other access points and services such as radar, medical devices, and satellite transmissions. In some coun- tries, radar and satellite use the same frequencies as 802. 11a. 802.11i A standard for improved security. It's also referred to as Wireless Protected Access 2 (WPA2). 802.11k A standard to make information for radio measurements, such as roaming requests by access points, statistics on device usage, and traffic levels in channels, available to WLAN management systems SO that they can balance traffic between access points. 802.11n A standard to increase throughput-actual user data trans- mitted and the range covered by each access point. Improve- ments achieved through enhancements in antennas that decrease effects of interference.
