This letter presents the measured path loss characteristics in microcellular residential and street environments at 3.4-, 5.3-, and 6.4-GHz band signals. Path loss characteristics on the different residential areas are thoroughly investigated and compared to a modified Hata model, and a new path loss model based on the modified Hata model is developed from the measurement of the residential area. A two-ray model is applied to analyze the path loss characteristics in a line-of-sight (LOS) street. Moreover, in a non-line-of-sight (NLOS) street, the power level decreases due to corner loss, and path loss exponents were investigated.
