A cabinet server and a data center where the cabinet server includes multiple function node layers vertically arranged to form a server core and multiple intra-cabinet antennas vertically arranged and disposed at one side of the server core, an intra-cabinet antenna is wirelessly connected to adjacent intra-cabinet antennas. A transmission path is formed of the vertically arranged intra-cabinet antennas when a radio signal is transmitted within the cabinet server. Since the intra-cabinet antennas are disposed at the side of the server core, electromagnetic radiation generated by the radio signal in a transmission process has a relatively small effect on the function nodes, thereby reducing the effect of the electromagnetic radiation on various electronic devices in the function nodes, improving service lives of the electronic devices, and improving transmission quality of the radio signal.

A positioning method based on a visible light source, a mobile terminal, and a controller. The method includes acquiring, by a visible light source controller, geographical position attribute information of a position at which a visible light source array is located, determining, by the visible light source controller according to a preset correspondence between geographical position attribute information of a position at which a visible light source array is located and a visible light source array pattern, a visible light source array pattern corresponding to the acquired geographical position attribute information, and controlling, by the visible light source controller according to the determined visible light source array pattern, the luminance state of each visible light source included in the visible light source array. Hence the method reduces the complexity of a positioning process.
