无线局域网和建筑物内的个人通信业务的潜在实现方法都要求对室内信号传输有透彻的理解.本文中,对室内不同材料的穿透损耗的测量是在频率为2.4GHz(ISM频带)上进行的.为了获得测量的数据,试验以2.4GHz为中心频率的160MHz带宽范围内进行,并使用了向量网络分析仪.这一测试将有助于未来在这一频段的室内无线网络的研发工作.
Potential implementations of wireless LANs and personal communication services in buildings require a thorough understanding of indoor signal transmission. In this paper, penetration loss measurements of different materials in a room are measured at a frequency of 2.4 GHz (ISM band) In order to obtain the measured data, the test was conducted at a frequency band of 160 MHz centered on 2.4 GHz and a vector network analyzer was used, which will facilitate the future development of indoor wireless networks in this band.
