In cellular mobile communications, the number of customers who use cellular phones indoors is rapidly increasing. Many examinations have been reported about the outdoor propagation loss characteristic, and the propagation model and the presuming method are standardized. On the other hand, although the presumed type based on an experiment has been proposed about the propagation loss characteristic, examination of the physical model which can take into consideration the size of a passage and the number of passersby (passerby density) in detail is carried out.So far, the propagation loss properties for one or two persons from the experimental and numerical points of view have been studied in our laboratry. In this study, the shadowing attenuation when people exist between the transmitter and receiver are calculated numerically. In this thesis, the two dimensional indoor model is built and the wave propagation for the specific condition such as the position of Tx and Rx is calculated byusing the FDTD method. The electric field distribution in indoor is examined for various kind of condition.
