| Abstract(in English) | It is being expected to control the flight of drones and transmit video data taken with drones using cellular network. When the mobile terminal on the drone communicates in the sky using current cellular network, it interferes with a wide range and the radio quality of the mobile terminals on the ground is deteriorated. We proposed “3D Cell Structure” which shares the same frequency by spatially separating the ground cell and sky cell by using 5G antenna beamforming for the base station antenna. In this paper, we evaluate the communication characteristics when mobile terminal on the drone communicates in a conventional cellular system and evaluate its effectiveness in comparison with the proposed system. |
