It analyzes pares sev-eral different positioning algorithms and the optimization algorithm of which location fingerprinting positioning method, uses thecosine distance function to value the conformity of fingerprint database. The optimized algorithm considers two aspects putational and storage advantages. It has a low dependence on the radio propagation model and the distance betweensites, and also has the advantages of high location accuracy, which is proved by coverage and handover optimization results onthe work :Measurement report; Location fingerprinting p
