Abstract (in Japanese) (See Japanese page) 
(in English) In recent years, there has been an increasing need for automatic driving and remote control by wireless communication of robots. Since low-floor robots perform wireless communication with an antenna height of several tens of centimeters, it is possible that the received power will decrease depending on the ground and surrounding structures. In this paper, we conducted outdoor propagation experiments with an antenna height of 5 cm to 40 cm, a frequency of 920 MHz, 1.9GHz, 2.4 GHz, and 5 GHz, and clarified the propagation loss characteristics. By comparing the theoretical formula of the two-wave model with the measurement results, the range in which the propagation loss of the two-wave model matches with respect to the frequency and height of the antenna was clarified. We also considered the relationship with the Fresnel zone.
