Abstract

Recently, mobile networks employing high-speed high-capacity communications have been investigated extensively to satisfy the demand for the faster and larger data communication. As one of the approaches, High-SHF (6-30 GHz) and EHF (mainly 30-60 GHz) bands are the candidates to utilize the relatively wide frequency band widths. As one approach, High-SHF (6-30 GHz) and EHF (mainly 30-60 GHz) bands are candidates to utilize the relatively wide frequency bandwidths. Accordingly, the characteristics of radio propagation loss in the frequency bands must be characterized. We investigate the characteristics of radio propagation loss in a street cell environment in the High-SHF bands using Ray Tracing (RT) based on measurement results. We observe that RT calculation tends to exhibit estimation error as the frequency increases.
