摘要: Fingerprinting is a technique that records vectors of received power from several transmitters, and later matches these to new measurement position the user. This paper examines data used in earlier fingerprinting experiments WiFi network characterize eventual positioning errors. The implied relationship between real distance ldquovectorrdquo fingerprints tested found be poor. However, because algorithms use nearest neighbour techniques, nearby were examined better behaved.
