A method for preparing an ordered cross-stacked metal oxide nanowire array is provided. The method includes the following steps: conducting synthesis by using an amphiphilic diblock copolymer as a structure directing agent, tetrahydrofuran (THF) as a solvent and polyoxometalates (POMs) as an inorganic precursor, where the diblock copolymer can interact with POMs via an electrostatic force to form a core-shell cylindrical micelle in the solvent, which self-assembles to form an ordered multilayer-crossed organic-inorganic composite nanostructure during an evaporation process; the template is removed by calcination in air, thereby obtaining ordered and crossed metal oxide nanowires with various elements doping. The nanowire array material has a high specific surface area, a high crystallinity, and realizes uniform doping of heteroatoms.

A server including data loading, data analysis, transformation and cleaning (TAC), and position estimation modules. The data loading module loads original position data (OPD) sets. OPD points of the OPD sets refer to positions of a wireless device in communication with a wireless station. The data loading module loads each OPD set based on an identifier of the wireless station in a corresponding one of the OPD sets. The data analysis module: determines an overall bounding area based on the OPD points; divides the overall bounding area into minimum bounding areas; and assigns the OPD points to the minimum bounding areas. The TAC module: transforms and cleans some of the OPD points to provide updated points, such that the updated points have a less number of points than the some of the OPD points. The position estimation module estimates a position of the wireless device based on the updated points.
