A positioning method includes: first, receiving wireless signals respectively at the positions of a number of training positions so as to extract a number of signal characteristics; next, establishing a positioning database according to the relationship between the training positions and the corresponding positioning module; then, classifying the training positions and the corresponding signal characteristics into a plurality of clusters, wherein when conducting positioning on a positioning node, a characteristic matching is conducted to find out a major cluster most similar to the positioning node; after that, conducting the characteristic matching between the positioning node and the training positions in the major cluster to decide a most-likely position of the positioning node. In addition, the present invention also provides a positioning system using the above-mentioned method.
