  • Wireless communication system and method and expansion unit of flat network architecture
    Patent number: 9838885
    Abstract: Disclosed are a wireless communication system and method and an expansion unit of a flat network architecture. The wireless communication system comprises at least one baseband signal source, an expansion unit (EU) and at least one remote radio unit (RU) connected to the EU. By overlapping the baseband signals output by each baseband signal source, remote transmission and wireless coverage of multimode digital signals are achieved, thereby solving the problem of system performance degradation caused by the interaction of radio-frequency analog signal transmission and optical transmission in the prior art.
