A novel path loss model under an indoor stair environment with antenna‐height dependency at the 2.6‐GHz band is proposed in this paper. In order to describe the attenuation caused by the variation of antenna height, a new height attenuation factor (HAF) is added to the usual local path loss model. The path loss exponent and the antenna‐height‐dependent factor are obtained by using the least squares method. Besides, the influence of antenna height variation on the shadowing effects is studied, and an empirical expression of the standard deviation about antenna height is obtained. The proposed model is verified by several measurement results. The results show that the proposed model is effective and can be employed for the future fifth‐generation (5G) ubiquitous wireless communication system design. © 2015 Institute of Electrical Engineers of Japan.
