Abstract :
This paper reports the variation of indoor radio channel caused by metal door. The simulation results using the finite difference time domain (FDTD) method and measurement results using the vector network analyzer in frequency domain are used for the characterization of received signal strength variation by metal door. Target frequency bands are three - sensor band, 802.11b ISM band, and 802.11a UNII band. From the simulation and measurement results, the effect of door angle to the received signal strength in three frequency bands and effect of radio frequency to variation are investigated. And FDTD simulation parameters for different environments are suggested.
