This study focuses on human body shadowing on the propagation characteristics of local-5G frequency bands in indoor environments, since the development and demonstration of the local 5G system, which is a 5G system that various entities such as local companies and local governments can construct flexibly on a spot basis in their own buildings and premises according to the individual needs of the community and industries, has been conducted since last year. We modeled an indoor propagation environment assuming a conference room containing human bodies and evaluated the propagation characteristics through a large-scale 3D numerical analysis based on the FDTD method. The electric field distribution in the conference room environment exited by the 4.7GHz transmitting antenna, which is used as the local-5G frequency, was calculated, and the propagation characteristics with and without the human bodies were compared. Shadowing and scattering effects due to multiple human bodies in standing and sitting postures were evaluated in the simulations. |
