Characteristics of the 60 GHz indoor wireless propagation based on ray tracing with human body movement

In this paper, an extended two-dimensional (2D) ray tracing algorithm is proposed to investigate the characteristics of indoor wireless propagation. A random variable, which serves as the extension to the classic 2D ray tracing algorithm, is introduced to study the human body movement effects to the propagation. Based on the proposed ray tracing algorithm, the path gains and delays are simulated under a variety of different settings. Simulation results and analysis show that the movement of human body degrades the transmission qualities.
