With the development of mobile communication technology, the 5th generation mobile communication (5G) networks have been officially in use and built in a large scale. As an key technology of 5G, Massive MIMO technology has the advantage of large system capacity, wide coverage and strong anti-interference capability. On the basis of introducing Massive MIMO technology and beam forming, this paper analyzes the equipment configuration of Massive MIMO. Equipment cost, user value, terminal distri- bution and brand reputation are combined to construct tridimensional and hierarchical network through sub-scene deployment and utilizing different equipment configuration. Finally, a method to build low-cost and high-quality 5G communication network is pro- posed.
