我们目前在2.45 GHz的测量结果，以评估阻塞/阴影和衰落的影响，由于家具和人旁边的终端短距离室内通信系统。结果如下：在终端附近穿过链路的人可能导致高达20 dB的衰落，这比测量的约5-13 dB的家具阻塞要大，这取决于链路上的物体;还通过在接收端使用双极化天线测量了极化耦合，并且对于被阻塞的链路耦合更高，这建议使用极化分集（参见Kim，S.，“室内无线通信信道的建模与分析”，博士。布鲁克林理工大学论文，1995年）。
We present measurement results at 2.45 GHz to evaluate blockage/shadowing and fading effects due to furniture and people next to terminals for short range indoor communication systems. The following are the results: people crossing the link near to a terminal can cause fading of up to 20 dB, which is more than the measured furniture blockage of about 5-13 dB, depending on objects over the link; polarization coupling was also measured, by using a dual polarized antenna at the receiving end, and coupling is higher for obstructed links, which suggests the use polarization diversity (see Kim, S., "Modeling and Analysis of Indoor Wireless Communication Channel", Ph.D. Thesis, Polytechnic University, Brooklyn, 1995).
