Generally, a power network has a power supplier (Utility or Provider) that produces and supplies electric power, and a consumer who consumes electric power from a power supplier.

The power supplier establishes a power contract with the consumer and charges the consumer according to the power consumption of the consumer based on the power contract. The power consumption of the consumer is measured by a power meter installed in the premise and is initially charged, and the power supply staff directly reads the power consumption of the meter.

Since then, the employees of the power supplier have advanced to the technology of collecting the power consumption of the electric power meter installed in the customer's house through AMR (Automatic Meter Reading) network.
