128bit毎分IoTデバイスを用いた準実時間移動軌跡送信システムの開発

抄録

The ELTRES developed by Sony is an IoT device capable of communicating over 100 km despite its low power. ELTRES has a built-in GPS to synchronize data between transmitter and receiver in order to achieve long-distance communication at low power. ELTRES has a stand-alone function to transmit location information as 128-bit data, but it can also send 128-bit data from outside. In this study, we developed a method of compressing the location information obtained from ELTRES at regular time intervals and transmitting 12 to 30 points of location information every minute. In this paper, we introduce the developed system and report the results of measurements using the system.
