Abstract
A network system includes: a wireless base station configured to relay communication performed by wireless terminals; distributed antennas each being configured to be connected to the wireless base station and form a cell that enables communication with the wireless terminals; direct-current grids each being arranged in a predetermined form in a communication area formed by the cells and configured to interchange power with power devices connected to the subject direct-current grid; a power gate arranged between the direct-current grids located adjacent to each other and configured to interchange power between the adjacent direct-current grids; and a control device configured to control the power gate based on information acquired from the power devices via the distributed antennas. The power devices connected to the direct-current grids are configured to perform communication with the control device via the distributed antennas that form the communication area including the direct-current grids.
