Successful development of common firmware supporting international wireless communication standards Wi-SUN Enhanced HAN and Wi-SUN FAN 1.1

The research group led by Professor Hiroshi Harada at the Graduate School of Informatics, Kyoto University, has successfully developed common firmware that operates on a single hardware platform for the international wireless communication standards "Wi-SUN Enhanced HAN" (used for in-home wireless networks in smart meter systems) and "Wi-SUN FAN" (used for outdoor wireless networks). This achievement is expected to reduce the cost of deploying wireless equipment for smart meter systems and contribute to more efficient infrastructure operation.

Key points

• Successfully developed unified firmware compatible with international wireless communication standards for both in-home and outdoor wireless networks
• Enables seamless connection of information collected from sensors, meters, and monitoring devices installed in homes and buildings to wide-area communication networks through multi-hop relay communication using up to 24 wireless devices
• The IoT (Internet of Things) routing functionality of Wi-SUN Enhanced HAN enables integrated meter reading for electricity, gas, and water meters
