Experimental investigation of 1.5-GHz, 2.3-GHz, and 2.6-GHz band land mobile radio propagation in urban and rural areas

Urban measurements were carried out in the Tokyo metropolitan area and rural measurements in the Hiraiso region. Radio propagation loss was measured at 2 cm intervals along the measuring routes, and median propagation losses in the three frequency bands was compared. In the urban experiment, the influence of obstacles on median values of radio propagation loss is almost the same in the three frequency bands except for the constant propagation loss factor, which is different for each frequency. The average difference in the median value of propagation loss between the 1.5 GHz band and the 2.3 GHz band is about 5 dB, while that between the 1.5 GHz band and the 2.6 GHz band is about 8 dB. >
