| 摘 要： | 在规划设计宽带无线网络过程中,合理地选取接入点(AP)的位置将对系统的性能和造价产生重要的影响。在无线局域网(WLAN)中,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。对宽带无线信号的楼内传播特性进行了测量,并将测量结果和分析数值进行比较,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,开发了一种用于在规划WLAN时预测AP覆盖范围的辅助软件。

| Abstract: | In designing of broadband wireless network,the sound selection of the position of the Access Point will greatly decide the performance and the cost of the whole system.In the In-building WLAN,different kind of obstacles effect the propagation of2.4GHz wireless signal and result in a special path loss.The In -building propagation of2.4GHz wireless signal is measured.By comparing the measured data and the predict data,a In-building path loss model for2.4GHz wireless signal is obtained.Based on the model,a software helping to predict the coverage of the Access Point is developed. |
