虎皮兰作文IEEE Std 802.11™ devices may be ud in environments where the physical layer properties are rapidly changing and where very short-duration communications exchanges are required. The purpo of this stan-dard is to provide the minimum t of specifications required to ensure interoperability between wireless devices attempting to communicate in potentially rapidly changing communications environments and in situations where transactions must be completed in time frames much shorter than the minimum possible with infrastructure or ad hoc IEEE 802.11 networks. In particular, time frames that are shorter than the amount of time required to perform standard authentication and association to join a BSS are accommodated in this amendment.
This specification accomplishes the following:
•Describes the functions and rvices required by stations to operate in a rapidly varying envi-ronment and exchange messages without joining a BSS
•Defines the signaling techniques and interface functions ud by stations communicating out-side of the context of a BSS that are controlled by the IEEE 802.11 MAC
This amendment to IEEE Std 802.11™ is bad on extensive testing and analys of wireless communica-tions in a mobile environment. The results of the efforts are documented in ASTM E 2213-03, "Standard Specification for Telecommunications and Information Exchange Between Roadside and Vehicle Systems -5.9 GHz Band Wireless Access in Vehicular Environments (WAVE) / Dedicated Short Range Communica-tions (DSRC) Medium Access Control (MAC) and Physical Layer (PHY) Specifications". This document is available from: ASTM International, 100 Barr Harbor Drive, PO Box C700, West Conshohocken, PA, 19428. This amendment to IEEE 802.11 is bad on the ASTM E 2213-03 document.

Urs of IEEE standards should be aware that the documents may be superded at any time by the issu-ance of new editions or may be amended from time to time through the issuance of amendments, corrigenda, or errata. An official IEEE document at any point in time consists of the current edition of the document together with any amendments, corrigenda, or errata then in effect. In order to determine whether a given document is the current edition and whether it has been amended through the issuance of amendments, cor-rigenda, or errata, visit the IEEE Standards Association web site at
ieeexplore.ieee/28 xpl/standards.jsp, or contact the IEEE at the address listed previously.
