Foreword
The Subclauses 6.4.1, 6.4.2, 6.4.3 and 6.4.7 of this Part are mandatory, while the rest are recommended.
This Part revised and adopted the international standard ISO/IEC 8802-11:2005/Amd4:2005 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: Further Higher Data Rate Extension in the 2.4 GHz Band (2005 English Edition).
This Part is sub-item of GB 15629.11-2003 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. In addition to the further higher data rate extension in the 2.4 GHz Band must comply with the provisions of this Part, the wireless LAN and other characteristics must comply with the provisions of GB 15629.11-2003 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, Clause 6 of GB 15629.1102-2003 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: Higher-Speed Physical Layer Extension Specification in 2.4 GHz Band, as well as other national standard on the extension sub-items.
Compared with ISO/IEC 8802-11:2005/Amd4:2005, the major technical differences of this Part are as follows: Add relevant Chinese contents in the Clauses and Annexes related to the radio emission.
For the ease of use, compared with ISO/IEC 8802-11:2005/Amd4:2005, the structure of this Part has made the editorial adjustments, which can be referred to in Annex NA. The Annex NA lists the clause correspondence between this Part and GB 15629.11-2003. In this Part, Annexes A, B, C and D are normative; while the Annex NA is informative. This Part was proposed by Ministry of Industry and information Technology of the People’s Republic of China.
