EM114039 is a single-phase smart electricity meter, which supports LoRaWAN remote communication, has built-in relay, can realize remote control of relay on/off, and remote meter reading, It is widely used in smart cities and power distribution systems of the Internet of Things. The primary frequency band used for LoRaWAN in India is the IN865-867 MHz band. This falls within the license-exempt ISM (Industrial, Scientific, and Medical) band, which is crucial for cost-effective deployment as it doesn't require spectrum licensing.
