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
