| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | Development towards the 5-th generation mobile communication system (5G) has been proceeding. There are many terminal stations up to 4G after introducing 5G. However, the concept of controlling the amount of interference of the managed wireless nodes and maximizing the frequency utilization for the entire network has been proposed. As a fundamental study in such an environment where many IoT terminal stations exist, we are studying to grasp the propagation characteristics of the terminal station side. In this paper, we describe the results of evaluating the propagation loss characteristics in the 2.4 GHz band using hexahedral antennas which can receive waves from all the directions when considering IoT terminal stations. It is shown that the propagation loss coefficient with respect to the transmission distance is between 2 and 4 by the difference of the surface on the hexahedral antennas, and that the propagation loss coefficient changes by the difference in polarization. Moreover, we verify that the tendency of the propagation path loss in terms of the antenna height is different depending on the antenna installation environment of the base station. | |
