JapanMIC working on development of 920 MHz RFID regulation
Active low power wireless systems in the 920MHz band are widely used for mobile identification (RFID), smart meters, sensor networks, etc.
In recent years, narrowband communications (LPWA), which can transmit power over long distances, are becoming more widespread as sensor networks. In Japan. this system is equipped with a carrier sense function to share the frequency between the systems, while in other countries, frequency hopping and low duty cycle functions are in use. Therefore, the need for harmonization with other countries is increasing.
In light of these needs, the Ministry of Internal Affairs and Communications studied the necessary technical conditions for the introduction of a system that does not require a carrier sense function. Based on this report, the MIC decided in January to develop regulations for 920 MHz RFID.
