Introduction of GB 15629.11-2003/XG1-2006

Information Technology — Telecommunications and Information Exchange between Systems — Local and Metropolitan Area Networks — Specific Requirements — Part 11: Wireless LAN Medium Access Control (MAC) and Physical Layer (PHY) Specifications 1 Overview 1.1 Scope The scope of this part is to develop a medium access control (MAC) and physical layer (PHY) specification for wireless connectivity for fixed, portable, and moving stations within a local area. 1.2 Purpose The purpose of this part is to provide wireless connectivity to automatic machinery, equipment, or stations that require rapid deployment, which may be portable or hand-held, or which may be mounted on moving vehicles within a local area. This part also offers regulatory bodies a means of standardizing access to one or more frequency bands for the purpose of local area communication. Specifically, this part: — Describes the functions and services required by a this part compliant device to operate within ad hoc and infrastructure networks as well as the aspects of station mobility (transition) within those networks; — Defines the MAC procedures to support the asynchronous MAC service data unit (MSDU) delivery services; — Defines several PHY signaling techniques and interface functions that are controlled by this part MAC; — Permits the operation of this part compliant device within a wireless local area network (LAN) that may coexist with multiple overlapping wireless LANs; — Describes the requirements and procedures to provide privacy of user information being transferred over the wireless medium (WM) and authentication of this part compliant devices. 2 Normative References The following normative documents contain provisions which, through reference in this text, constitute provisions of this part of GB 15629.

An ad hoc network is typically created in a spontaneous manner. The principal distinguishing characteristic of an ad hoc network is its limited temporal and spatial extent. These limitations allow the act of creating and dissolving the ad hoc network to be sufficiently straightforward and convenient so as to be achievable by nontechnical users of the network facilities; i.e., no specialized “technical skills" are required and little or no investment of time or additional resources is required beyond the stations that are to participate in the ad hoc network. The term ad hoc is often used as slang to refer to an independent basic service set (IBSS)
