Claim:
1. A three-phase power line communication apparatus, comprising: a transceiver configured to transceive communication information and reading data with a plurality of meters installed on three phases for three-phase power line communication, through communication with the plurality of meters; and a controller configured to: establish a network group for each of the three phases based on the communication information received from the plurality of meters; generate a communication plan for communication with each of the network groups by analyzing a communication performance of each of the network groups; control communication with the plurality of meters based on the communication plan; transmit a test signal to the plurality of meters included in each of the network groups, at least once; receive a response signal to the test signal from the plurality of meters; and analyze a communication performance of each network group based on a reception result of the response signal, wherein the analysis of the communication performance comprises measuring an average response time and a communication success rate of the plurality of meters based on a reception result on the response signal and analyzing a communication performance of each network group based on a result of the measurement.
