A smart meter is an electronic device that can record information such as power consumption, voltage level, current, and power factor. Smart meters communicate information to consumers to make consumption behavior clearer, and electricity suppliers communicate it to system monitoring and customer billing. Smart meters usually record energy in near real-time and report regularly at short intervals throughout the day. [7] The smart meter can realize two-way communication between the meter and the central system. The difference between this advanced metering infrastructure (AMI) and automatic meter reading (AMR) is that it enables two-way communication between the meter and the supplier. The communication from the meter to the network can be wireless or through a fixed wired connection (such as a power line carrier (PLC)). Commonly used wireless communication options include cellular communication, Wi-Fi (easy to use), wireless ad hoc network over Wi-Fi, wireless mesh network, low power long range wireless (LoRa), ZigBee (low power, low data rate wireless) ) And Wi-SUN (Smart Public Network).
