Path loss measurements and modeling for indoor office scenario at 28 and 38 GHz

摘要

In this paper, we present the experimental path loss models for a typical indoor office propagation scenario. Channel measurements have been performed using a wideband channel sounder in the 28 and 38 GHz frequency bands. We derive path loss exponents and shadow fading factors based on the two popular path loss models, i.e., Close-in (CI) free space reference distance model and Floating-intercept (FI) model. Our measurement results show that the CI model is more appropriate for indoor path loss modeling than the FI model.
