【摘要】 近年来，无线宽带技术蓬勃发展。随着技术的进步，无线宽带网的建设也开始进入高速发展阶段。许多国家均在政府支持和电信制造商、运营商的积极投入下，研究和建设各种不同类型的无线宽带网络。这当中，基于WiMAX技术的无线宽带网由于传输速度快、覆盖范围广、抗扰能力强、灵活易部署的优点成为该领域研究的热点。本文首先介绍WiMAX物理层和MAC层的关键技术，并通过与WiFi、蓝牙、3G等其它无线宽带接入技术进行比较，阐述采用WiMAX技术搭建无线宽带网的理由。在针对WiMAX的无线信道信道模型进行了详细研究的基础上，按照基于WiMAX技术的无线宽带网络的规划方法，结合南昌大学的实际情况，提出了一套切实可行的无线宽带网设计流程和方案。依据此方案实际搭建了南昌大学无线宽带实验网，并且完成了部分测试、调试及优化工作，针对实际中出现的问题做出分析。最后，对全文进行总结，展望了下一步在无线宽带网组网技术方面可以进行的工作和改进。更多还原

【Abstract】 The wireless broadband technology has developed energetically in recent years.With the progress of technology, wireless broadband net construction is going intohigh speed development. Many countries are constructing different types of wirelessbroadband net based on government support, telecom operators and manufacturersgetting into the market. Because of its high speed transmission, wide cover range,good capacity of resisting disturbance, flexible disposition, the wireless broadbandnet based on WiMAX became a hot spot in the studying field.The paper has introduced WiMAX physical layer and MAC layer firstly, thenelaborated on the reason using WiMAX to construct wireless broadband net aftercomparing with other wireless broadband access techniques such as WiFi, blue tooth,3G etc. And we have worked over wireless channel model thoroughly. Then thedissertation has proposed feasible design cycle and program based on WiMAXwireless broadband net planning means and the realistic of Nanchang University. Wehas constructed Nanchang University wireless broadband testing net, finishing partsof testing, debugging and optimizing job. analyzing the problems appeared in the realwork. At last we have done a conclusion of the paper, taken a iong-tenn outlook inhow to improve the wireless broadband net grouping technique.更多还原
