Key technology for GB 15629.1102-2003
GB 15629.1102-2003: is the subset of 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 with the working frequency is 2.4GHz~2.4835GHz; it is the expansion regulations for physical layer of higher speed. Compared with GB15629.11, the DSSS physical layer regulation for 2.4GHz and the correlated interface is added. The modulation is complementary code keying (CKK); the speed is 11Mbit/s and 5.5Mbit/s, and could automatically change among 11Mbit/s, 5.5Mbit/s, 2Mbit/s and 1Mbit/s.
Key technology for GB 15629.1103-2003
