Abstract:
The commercial service of fifth generation mobile communication system started in the spring of 2020 in Japan. This paper discusses a highly precise prediction of 28 GHz millimeter wave indoor propagation characteristics in an office environment by using a large-scale electro-magnetic field simulation based on the finite difference time domain technique. The computer simulations are carried out using the high-performance computer system operated in Information Initiative Center, Hokkaido University. They give us a detail of electromagnetic field distributions in an FDTD problem space including targets at once although they require a lot of computer resources and a long running time in general. The paper compares calculated path loss model parameters such as path loss exponents, shadow factors and cross-polarization discriminations in the LOS environment with the measured ones demonstrated by the other research groups to confirm the effectiveness of numerical results and the accurate prediction of path loss model parameters.
