| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | 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. We have so far studied the shadowing properties for one or two persons from the experimental and numerical points of view. In this study, the propagation loss when people exist between the transmitter and receiver are calculated numerically. Human body is modeled by lossy dielectric cylinder and the propagation loss properties for the passerby density and distance are examined. It is shown that the propagation loss is expressed in terms of the propagation distance and passerby density. |
