%X To explore the feasibility of wireless communication in the high-frequency broadband, the large-scale fading characteristics of 9~12GHz in indoor office scenarios are studied. Based on a large amount of measured data, a novel path loss model with shelter loss is proposed for indoor non-line-of-sight scenarios with obstructions. The proposed model uses the shelter loss to compensate the effect caused by the shelter, and the relationship between the shelter loss and the frequency is analyzed. Moreover, the statistical characteristics of the shielding loss under different frequencies are also presented. The experimental results show that the shielding loss and the distance have an exponential function relationship when the shelter is stationary. The convergence speed of the exponential function decreases with the increase of frequency. When the shelter moves, the shielding loss and the distance satisfy a quadratic function relationship, and the position of the least shielding loss locates at the midpoint between the transmitter and the receive antennas as the frequency increases. The proposed model is benefit to the design of the future high-frequency indoor wireless communication system and the network deployment of microcells.
