Disclosed in an embodiment of the present invention is a network architecture for supporting MIMO technology and improving data service capacity. The network architecture comprises: an antenna remote unit and a radio remote unit (RRU). The antenna remote unit is allocated with N ports, and the RRU comprises M radio channels, wherein N is a positive integer greater than 1 and less than or equal to M, and at least two ports in the N ports are ports having different types. The antenna remote unit is connected to the M radio channels in the RRU via the N ports, wherein any one of the ports corresponds to at least one radio channel.
