Towards Practical Path Loss Predictions in Indoor Corridors Considering 5G mmWave Three-Dimensional Measurements

Theoretical and empirical foundations of how radio waves behave in practical wireless channels need to be fully revisited for millimeter-wave (mmWave) frequencies so that fifth-generation (5G) technologies may successful. Kriging is an outstanding geostatistal interpolation technique employs variography understand the spatial variability known samples at specific locations predict unmeasured samples, based on fact there implied connection between measured value its location space. The research we here report aimed validating improvement predictions when this tool included mmWave frequency path loss modeling a long indoor corridor with break. In order quantify accuracy proposed methodology, it compared well-established procedure described literature. Extensive path-loss measurements were collected through specialized narrowband sounders 28 60 GHz. Spatially averaged power using omnidirectional directive antennas different heights provided basis three-dimensional Kriging-aided model. It was found method significantly improves as considers all singularities site-associated features are implicit samples. This important obtain reliable model planning deployment communication systems scenarios.
