为了满足无线网络不断增长的需求,在要求速率不断提高和3G资费偏高的情况下,考虑到当前使用以太网建立热点方便,使用Wi-Fi(Wireless Fidelity)上网成为一种比较理想选择。通过设计Linux操作系统下基于三星S3C2440处理器ARM体系的Wi-Fi网络,并运用Qt creator集成工具开发了友好的网络连接界面应用软件。实验结果表明,所设计的Wi-Fi网络能够在软件操控下使用简单,通信稳定,较高速率,达到预期目标,并已成功运用于项目的网络接口开发。 In order to meet the growing demand for wireless networks, Wi-Fi (Wireless Fidelity) Internet access is an ideal solution considering the current need to establish hotspots with Ethernet, as demand rates continue to rise and 3G tariffs are high. By designing a Wi-Fi network based on Samsung S3C2440 processor ARM system under the Linux operating system and using Qt creator integration tools, a friendly network connection interface application software was developed. The experimental results show that the designed Wi-Fi network can be used under the control of software easily, with stable communication and high speed, achieving the expected goal and has been successfully applied in the project’s network interface development.
