要約(英語): The number of IoT service provider is increasing. Such IoT services require different-type wireless communication systems from conventional systems such as WiFi or LTE・5G, which can transmit large amount of data. Those wireless systems have a capability of low-power and long-distance communication by transmitting small amount of data with low duty cycle. There is, however, a challenging issue in radio propagations since IoT devices are located in harsh radio environments, especially for social infrastructure IoT service. In this paper, we analyze radio propagation from manholes which are used for social infrastructure such as gas, water supply and power grid to discuss solutions for long-distance and low-power wireless communications for social infrastructure.
