摘　　要：主要对Linux系统进行适当的裁剪、编译后,移植到ARM11微处理器中,并直接通过Linux2.6.38内核对网卡进行图形化界面的配置,使系统能够完全支持AR9271网卡,然后再利用hostapd应用程序与其配置文件hostapd.conf相配合,开启AP模式,在无需路由器的情况下即可构建一定范围内的无线局域网络,增强了整个系统的可扩展性和移动性;同时,在socket套接字基础上,设计了C/S模式下的网络通信,使远程PC与ARM 11远程服务器实现无线通信。实验结果表明,设置在AP模式下的ARM 11不仅能在不同场景下与远程PC构成稳定、可靠的无线网络化通信,而且针对常见的通信弊病,因构建的小范围局域网能够扩展通信范围,对通信具有一定的改善效果。The Linux system is properly cut and compiled,and transplanted into the ARM11 microprocessor. After graphical interface configuration for network card directly through the Linuχ2. 6. 38 kernel,the system can fully support the AR9271 card,and then uses the hostapdapplication matched with its configuration file hostapd. conf,opening the AP mode. In the absence of the routers,we can construct a range ofwireless local area network,which can enhance the scalability and mobility of the entire system. At the same time,based on the socket to design the C/ S mode of network communications,it makes the remote PC and the remote server ARM11 constitute wireless communication.Experiments show that ARM11 in the AP mode can not only establish a stable and reliable wireless network communication with remote PCin different scenarios,but also improve the effect of communication to a certain extent for common communication ills due to the construction of a small area LAN expanding the communication range.
