An Empirical Outdoor-to-Indoor Path Loss Model from below 6 GHz to cm-Wave Frequency Bands

摘要

This letter presents an empirical multi-frequency outdoor-to-indoor path loss model. The model is based on measurements performed on the exact same set of scenarios for different frequency bands ranging from traditional cellular allocations below 6 GHz (0.8, 2, 3.5 and 5.2 GHz), up to cm-wave frequencies (10, 18 and 28 GHz). The model has applicability similar to the typical 3GPP and ITU-R outdoor-to-indoor simplified models, including the multi-frequency formulation recently included in the 3GPP TR 38.900. This letter highlights some of the details behind these simplified models and provides additional modeling for internal multi-wall attenuation and associated shadow fading.
