A Novel 3D Kriging-Aided Path Loss Model for Indoor Corridors Considering 28 GHz Measurements

Abstract

While fast-growing, telecommunication students, researchers and engineers have to consider innovative approaches to continuously address user demands and provide progressive involvement in technology development, as well as its usefulness and support capabilities for indoor consumers. Through an outstanding and specialized narrowband sounder, this research employed three-dimensional (3D) radio measurements in indoor corridors at 28 GHz, where complete coverage of 360-degree scans at each measured location were assessed. Based on the experimental measurements, when Kriging was included, path loss predictions were more accurate, reducing the RMSE by more than 50%, suggesting a reliable path loss model for planning and deployment of wireless communication systems in indoor corridors.
