To establish a simulation technology for estimating and predicting radio propagation characteristics with short calculation time and high accuracy, we proposed a novel method named color images method (CIM) and showed its high performances at low frequency band of 1 GHz. However, the performances of the CIM in high frequency bands have not been clarified. In this paper, we compare estimated path loss results of an outdoor urban environment using the CIM with the measured results in high frequency bands of sub-6 GHz band and millimeter-wave to clarify the estimation performance of the CIM. The root mean squared errors (RMSEs) of the difference between the estimated results and the measured results are small about 8 dB for all frequencies. The calculation time is extremely short.
