Abstract:In an indoor wireless environment, the presence of the human bodies significantly influences the radio link between the access point and user equipment due to their low heights. It is essential to include human body models in the most widely used deterministic propagation models, wherein the human body has to be approximated to certain geometry and associated electromagnetic properties. The circular conducting/dielectric cylinder is the most widely used geometrical approximation for the standing posture of the human body. By visual inspection, the human body form does not appear to be symmetric and uniform at different heights, unlike cylinders. Furthermore, the dielectric nature of the human body may cause frequency-dependent human-radio interaction. Therefore comparative measurement and deterministic modelling of human-radio interaction at sub-6GHz and higher frequencies considering the accountability of cylinder simplification at different height is the main goal of this project. The frequencies of choice, one at mid-band sub-6 GHz and one at high-band close to 20 GHz, are represented in the current development of 5G. This work re-evaluates the accountability of using cylinder geometry at both sub-6GHz and higher frequencies.
