Smallest Sensor Device Supporting LPWA Communication for no more Battery replacement
The spread of IoT systems has progressed in recent years, and it is predicted that by 2020, several tens of billions of IoT devices will be connected to the cloud through networks. In IoT systems, information collected from multiple sensors installed in the field, need to be transmitted to and analyzed on the cloud, and LPWA has been gaining attention as a wireless technology that can directly transmit data to the cloud with low power consumption across a wide area. From a convenience and cost standpoint there are high hopes for miniaturization, which not only meets the LPWA standards, while utilizing solar cells that eliminate the need for replacement.
