Description

technical field [0001] The invention belongs to the technical field of broadband power carrier communication, and in particular relates to a test system for seven-stage relay communication of a power line broadband carrier communication module. Background technique [0002] In recent years, as Qualcomm Atheros and Huawei HiSilicon have successively launched power line broadband carrier chips for energy management and home automation, power line broadband carrier technology has gradually replaced narrowband power line carrier technology with the advantages of more stability and higher speed, and entered the energy meter Automatic meter reading system, street light control and smart home. However, for the networking test of the power line broadband carrier communication module, there is no mature solution that can simulate a complex field environment to test the relay communication performance of the module. [0003] The Chinese invention patent application with the publicati...
