The invention discloses small base station equipment. The small base station equipment comprises an upper box body, a lower box body and a plurality of functional module structures, wherein the plurality of functional module structures are buckled and sealed in the upper box body and the lower box body, and the relative positions of the functional module structures are positioned through a plurality of groups of matching pairs. According to the small base station equipment, each functional module structure is buckled and sealed in the upper box body and the lower box body by utilizing a plurality of groups of matching pairs, and the relative positions of the functional module structures are positioned; the nearby connection of each functional module structure is realized, the size of the small base station equipment is reduced, and the single-person carrying, opening and erecting work of the base station equipment and the safety protection in a working and transportation state are realized. Besides, the whole small base station equipment integrates radio frequency, baseband, core network and part of service functions, and is provided with an external interface and a mounting hole,thereby facilitating expansion, maintenance and installation.
