Summary

This chapter presents the principles of radio frequency (RF) fingerprinting methods, also known as database correlation methods (DCMs). Although there is a wide variety of DCM implementations, they all share the same basic elements. These elements are identified and analyzed in the chapter. The chapter discusses different alternatives for building RF fingerprint correlation databases (CDBs), and discusses the advantages and drawbacks of each of them, as well as their impact on the positioning accuracy of location services based on DCM. It presents different methods to numerically evaluate the similarity between each fingerprint within the CDB and the measured RF fingerprint, including an artificial neural network (ANN)-based approach. The chapter analyzes two alternatives to reduce the correlation or search space. Finally, it uses field tests to evaluate the positioning accuracy of fingerprinting techniques in both Global System for Mobile Communications (GSM) and Wi-Fi (wireless fidelity) 802.11b networks.
