| 中文摘要 | 针对无线仪表控制系统中,中继站置于楼侧的情况,探讨了433MHz和900MHz无线信号在楼内楼间的传播特性。在给出了一组窄带信号在商业楼和住宅楼的测试结果并做出统计分析后,研究了收发信机间距离和相对位置,接收机所在房间的窗户大小,以及房屋结构,天线方向等因素对屋内信号强度分布的影响。证实了由对电磁波封闭效果极好的钢筋混凝土浇筑而成的现代建筑物中,屋内的信号主要是由窗户绕射进入的。; The propagation of radio waves within buildings at 433 MHz and 900 MHz was investigated where the wireless communication system relay is placed on the sidewall of the building. Statistical analysis of measurements obtained in a commercial building and in a residential building was used to analyze the influence of various parameters on the signal strength distribution in a room. The parameters include the distance from the relay, the relative position of the transmitter and the receiver, the window size, and the room area and structure. The results show that the signal in a room is mainly due to the windows.; 国家"九七三"基础研究基金项目(G2000036508) |
