Study on 60 GHz Millimeter Wave Propagation Characteristics Inside a Bus Based on SBR/IM Method

Based on shooting and bouncing ray tracing/image method (SBR/IM), millimeter wave (mmWave) propagation characteristics was simulated and analyzed inside a bus at 60 GHz. The statistical analysis of simulation results considering large scale fading and delay parameters has been performed, such as path loss and root mean square (RMS) delay spread obtained for some fixed positions in the bus, providing good agreement with statistics for known literature. In addition, the path loss of the aisle and the received power of the whole intra-vehicle are simulated and analyzed. This study, which provides a theoretical basis for simplifying the millimeter wave propagation model in intra-vehicle, is conductive to the network planning and optimization of wireless communication within the vehicle, and lays the foundation for the future development of the fifth generation mobile communication technology.
