Abstract
Channel measurement and modeling are fundamental and critical for the analysis and simulations of communication systems. For the fifth generation (5G) cellular network, the wireless channel characterization in its application scenarios, such as the (eMBB) and (mMTC), is critical. In this paper, we investigate the radio propagation at 900 MHz, 2.6 GHz, and 3.5 GHz in (O2I) scenario. We performed the channel measurements using a multi-frequency narrow-band sounder to derive the large-scale fading parameters such as the path loss and shadow fading. Then, based on the measurement data, we analyze the differences of the large-scale fading parameters at the three frequencies and the impact of frequency on the channel characteristics. Furthermore, we compare the accuracy of three path loss models specified in the WINNER and 3GPP channel modeling standards according to the measurement results. Finally, we propose the modification on the model coefficients to fit the measurement results better for various carrier frequencies in the O2I scenario. The measurement data and revised channel model can support the signal coverage analysis and subsequent communication system optimization.
