Claim:
1. A method for searching a nearby apparatus, adapted for searching the nearby apparatus located near a first apparatus, comprising: searching at least one hotspot nearby by using a wireless communication technique, obtaining an identifier of each hotspot to generate a first identifier set, calculating a signal intensity of each hotspot, and uploading the first identifier set and the calculated signal intensities to a server by the first apparatus; searching at least one hotspot nearby by using the wireless communication technique, obtaining the identifier of each hotspot to generate a second identifier set, calculating the signal intensity of each hotspot, and uploading the second identifier set and the calculated signal intensities to the server by at least one second apparatus respectively; sorting the identifiers in the first identifier set and in each of the second identifier sets according to the signal intensities, and selecting a plurality of identifiers sorted ahead in the first identifier set and in each of the second identifier sets to calculate a similarity between the first identifier set and each second identifier set by the server; determining whether a corresponding second apparatus is the nearby apparatus located near the first apparatus according to the similarity, and providing a determination result to the first apparatus by the server; sequentially comparing the signal intensities corresponding to the identifiers sorted ahead in the first identifier set and in each of the second identifier sets by the server; and if at least two of the identifiers sorted ahead in the first identifier set and in each of the second identifier sets having a difference of the signal intensities less than a second threshold, determining the second apparatus corresponding to the second identifier set as the nearby apparatus located near the first apparatus.
