FDTD-Based Numerical Estimation of Human Body Blockage Characteristics in 26GHz Band Indoor Propagation

The aim of this study is to develop an accurate and reliable method of estimating propagation channels and propagation modelling so as to advance radio link design of fifth generation (5G) wireless systems. It was reported that in the high frequency bands used for 5G, shadow fading is large as is the loss due to human bodies. This paper elucidates the effects of human body blockage on 26 GHz-band propagation characteristics in an indoor environment. A novel method for estimating human body blockage characteristics based on large scale FDTD analysis is proposed. Electromagnetic field distributions inside an office environment created by a 26 GHz wireless transmitter are analysed and propagation characteristics are discussed.
