The embodiments of the present invention provide a method for positioning using wireless signal and a positioning server. The coverage area of wireless signal is divided into multiple grids. The method comprises: acquiring speed information of UE; and determining a grid, in which the UE is located, based at least upon the speed information of the UE and speed information of the grids. Accordingly, according to the embodiments of the present invention, when the UE is positioned by using the wireless signal, the grid in which the UE is located is determined by using the speed information of the UE and the speed information of the grids, so that pattern matching may be performed more accurately and the positioning precision is improved.
