Problems solved by technology

[0003] Broadband power line communication technology BPLC (BPLC: BroadPowerLineCarrier) technology will have the following problems in actual network deployment and application: when there is no available power line between nodes, the pair of nodes will not be able to use BPLC to communicate; when nodes When crossing the meter or transformer, the BPLC signal is greatly attenuated. At this time, the communication quality between nodes is very poor, or even unable to connect; when the nodes are severely interfered, the communication quality between nodes is very poor, or even impossible to connect.
[0005] In the above-mentioned BPLC network, PLC nodes and wireless nodes cannot directly network and communicate, and additional gateway equipment is required; PLC network operators need to maintain both the PLC network and the wireless network at the same time.
Although it solves the connectivity problem, this method has complex configuration, high configuration and operation costs, and difficult equipment maintenance
