IEEE802.11协议是目前最具影响力的无线局域网标准,但是目前的芯片都是国外公司设计的,本项目的目的就是为了研制具有自主知识产权的802.11芯片。介绍了SDL描述的IEEE802.11 MAC协议,并在理解协议的基础上,提出了在μC/OS-II实时操作系统中用C语言来实现MAC协议的方法,并由此在μC/OS-II操作系统中实现了整个IEEE802.11 MAC协议,为生产出具有自主知识产权的802.11无线网络芯片奠定了基础。
IEEE802.11 protocol is currently the most influential wireless LAN standards, but the current chips are designed by foreign companies, the purpose of this project is to develop 802.11 chips with independent intellectual property rights. This paper introduces the IEEE802.11 MAC protocol described by SDL, and on the basis of understanding the protocol, proposes a method to realize MAC protocol using C language in μC / OS-II real-time operating system, The entire IEEE802.11 MAC protocol is implemented in the operating system, laying the foundation for the production of 802.11 wireless networking chips with proprietary intellectual property.
