Abstract(in Japanese) (See Japanese page)
Abstract(in English) To realize reliable wireless communication, we measured 920 MHz band propagation characteristics in four factories. As a result, we first show the correlation between average of time fluctuation and distance in LOS environments. Second, we show that ”the probability of high propagation loss which governs reliability of communication” can be approximated by Rician distribution and we show the worst K-factors in each factory environment.
