建筑物内无线局域网信道特性分析

Analysis on Characteristics of Wireless Local Area Networks Channel in Building

随着社会信息化的快速发展,无线局域网通信技术日益普及。作为电脑、手机及电视等智能终端无线上网的重要场所,建筑物内部结构和设施复杂多样,为了合理设计和利用无线局域网,需要深入分析和掌握建筑物内的无线信道特性。根据无线局域网技术特点和建筑物内主要环境特征,基于电波传播机制,具体分析了无线信道传播损耗数据及预测模型并指出了工程应用中应注意的问题。

With the rapid development of society？informatization, the Wireless Local Area Networks （WLAN） technology is increasingly popularizing. Used as the important places for intelligent terminals such as computers, mobile phones, televisions and so on to connect to wireless internet, the buildings have complicated and diverse internal structures and facilities. In order to reasonably design and apply WLAN, the characteristics of wireless channels in buildings should be deeply analyzed and understood. According to the characteristics of WLAN technology and the main environment features in buildings, the propagation loss data of wireless channels and the prediction model are analyzed in detail based on the radiowave propagation mechanisms, and the problems which should be concerned in engineering application are pointed out.
