| Abstract(in English) | Recently, various applications for location sharing are used due to technological progress of mobile devices. In the near future, these will increase the use in the sea. Thus, it is important to understand the characteristic of communication quality in the sea. In this study, we evaluated the communication quality around Suo-Oshima in Seto Inland Sea. Measurement devices by Android and PC were set at the front and the back on Oshima-maru, a ship belonging to Oshima National College of Maritime Technology. They measured received signal strength indicators (RSSIs) and round trip times (RTTs) of communication with the server in Hiroshima City University. As a result of evaluation, it was confirmed that RSSIs increased and RTTs decreased due to increasing in distance from a base station to the ship and due to obstructions such as an island between the base station and the ship. Further, it was confirmed that RTTs of each measurement device set at the front and the back on the ship were different. We clarified that a diversity reception improved the RTTs performance. |
