Abstract
This paper describes the results achieved by various experimental campaigns aimed at characterizing the directional propagation channel in DCS/UMTS band (1.9 GHz) in indoor and forest areas for similar antenna heights at both ends. These experimental results are useful in the context of pedestrian radiolocalization systems relying on cell phone signals. Wideband data, are used to model the channel through various parameters: pathloss, shadowing, fading statistics, delay and azimuth-spreads. For indoor scenarios, path-loss exponents range from 1.4 to 2.2, while the shadowing, temporal K-factor, delay- and azimuth-spreads are found to be lognormally distributed. The RMS delay-spread ranges from 9 ns to 95 ns, whereas the azimuth-spread ranges from 20 to 140 degrees. In forests, the delay-spread, ranging from 60 to 120 ns, is strongly anti-correlated with the temporal coherence, and increases with transmit-to-receive distance. The azimuth-spread remains limited, with average values around 15 degrees.
