摘要 楼内无线信道的变参特性是设计宽带无线系统需要考虑的一个重要因素 .在 2 .4GHzISM频段上宽带无线信号受到楼内不同类型障碍物影响 ,产生了特有的信号衰减 .在测试平台上对宽带无线信号的楼内传播特性进行了测量 ,对测试结果和分析数值进行了比较 ,讨论了 2 .4GHz频段楼内无线传输路径衰耗的计算模型 ,分析了楼内宽带无线接入的性能 ,提出了楼内宽带无线接入网的实现方案 . The instability of wireless channel greatly affects the design of the in-building broadband wireless system.A broadband wireless transmission experiment shown the different path loss for 2.4?GHz wireless signal resulted from different obstacle in a building.Then the in-building path loss model for 2.4?GHz wireless signal is discussed and the broadband wireless access performance is analyzed by comparing the predicted data and the measured data.Solution of designing a broadband wireless access network in a building is presented.
