tworks for direct access to the subscriber. wireless local loop A technology that uses low-power radio transmission, cellular radio, and/or cordless telephony as an alternative to local loops for accessing the PSTN. wireless mesh network A wireless LAN that routes voice, data, and instructions between nodes, creating a resilient network in which connections are continuous, reconfiguring around blocked paths by hopping from node to node until a connection is established. wireless micromesh network A wireless network that is designed for short ranges, up to 300 feet (100 m) between any two nodes. It is characterized by long battery life, relatively low data rates, and good tolerance for latency. Wireless micromeshes eliminate the need to wire every node and thus provide the greatest degree of flexibility possible in sensor/control networks. wiring closet A location in a building where the building's wiring terminates and where equipment (e.g., hub electronics) is placed. WISP (wireless ISP) A company that gives users wireless access to the Internet and related services. WLAN (wireless local area network) A network that covers a single room to an entire campus and uses wireless media. The last link with the users is wireless, and the backbone net- work usually uses cables, with one or more WAPs connecting the wireless users to the wired network. WLANs typically operate on unlicensed frequency bands, and they do not require line of sight. WLL (wireless local loop) The use of a wireless communications link as the last-mile con- nection for delivering POTS and broadband Internet to customers. Also referred to as radio in the loop, fixed-radio access, or fixed-wireless access. WMAN (wireless metropolitan area network) WMAN (wireless metropolitan area network) A network that provides broadband wireless network access over a metro area. The WMAN standards most commonly used today BFWA, IEEE 802.16 (WiMax), WiBro, IEEE 802.20 (Mobile-Fi), HiperAccess, iBurst, Flash- OFDM, DMB, and VF. WML (Wireless Markup Language) A marku
