NB-IoT Prepaid AMI Smart Water Meter

NB-IoT developed by 3GPP is based on the Narrow Band Internet of Things Standard of cellular. At present, the domestic research and investment on NB-IoT has reached the advanced international level, like Huawei owns the core independent property rights of NB-IoT chip. 
The self-developed LAISON NB-IoT Smart Water Meter realizes bidirectional data communication between meter and Center System through NB-IoT Comm., thus realizing Meter Remote Prepayment, Real-time Meter Remote Communication, Remote On/Off  Value, ect. LAISON NB-IoT Water Meter complies to International STS Standard IEC62055-41,51, gets certified from STSA. Customers could purchase water through multiple methods (Vending Points, Agency, Customer Self-service, ect.), and obtain 20-digit recharge token. Moreover, the Center System can automatically send the recharge code to the corresponding smart meter through the NB-IoT network to recharge remotely without external keyboard input.
Meanwhile, meter data such as Hourly/Weekly/Monthly Consumed Water, Meter Battery Voltage, Running Status, ect. could be automatically uploaded to MDM System through NB-IoT for further data statistics and analysis. And diversified statistical reports can help Water Companies make decisions scientifically.
