Using entire 480 MHz frequency spectrums have been newly approved by IMT-Advanced through global discussion at ITU World Radio communication Conference (WRC-07). In Japan, 3.4-3.6 GHz band will be allocated as one of frequency bands for IMT-Advanced. There are several researches in the literatures to used frequency bands used for the 4G mobile communication systems. In this paper, the authors studied the propagation characteristics for 4.4-4.9 GHz frequency bands in macro-cellular environments in Japan.
