Indoor ultra-wideband location fingerprinting

Location fingerprinting based on ultra-wideband (UWB) radio frequency signals is an attractive alternative to conventional positioning concepts which utilize range, angle, or received signal strength estimates. The large bandwidth enables a fine temporal resolution of the multipath propagation channel, which in turn acts as a unique location fingerprint of the positions of transmitter and receiver. This paper presents a thorough experimental performance analysis of the proposed UWB location fingerprinting scheme in a typical office environment. We are able to show that high position location accuracy is achievable in a dense multipath propagation environment with non-line-of-sight conditions where conventional approaches would fail.
