Description

technical field [0001] The present invention relates to the technical field of communication networking, in particular to a 5G networking system based on millimeter wave and microwave multiple-input multiple-output relays. Background technique [0002] The target data throughput of the fifth-generation mobile communication 5G reaches tens of Gbps, and requires reliable connection, low latency, and high requirements for power consumption. In 5G technology, millimeter wave communication is one of the key technologies to realize 5G high-speed communication because of its broadband spectrum resources. [0003] However, in the millimeter wave frequency band, the transmission of electromagnetic waves has a large attenuation, and it will suffer a very large loss when penetrating obstacles. When encountering ordinary building materials, the attenuation of millimeter waves can even be above 100dB. Therefore, millimeter wave communication is limited to point-to-point communication a...
