Short Baseline Propagation Characteristics of Determinstic Wireless Fingerprinting Systems for Localisation

Fingerprinting is a technique that records vectors of received power from several transmitters, and later matches these to a new measurement to position the new user. This paper examines data from locations at very short ranges from each other in order to observe the nature of the relationship between short-range fingerprints. We find that even at short distances, variation due to fading dominates and a suitable signal model has yet to be produced. We also conclude that fingerprints should be averaged over a range near the point of interest.
