Title: Radio Wave Propagation Into Large Building Structures, Part 2: Characterization of Multipath
Published: April 02, 2010
Abstract: We report on measurements that characterize multipath conditions that affect broadband wireless communications in building penetration scenarios. Measurements carried out in various large structures quantify both radio-signal attenuation and frequency-selective distortion (multipath) in the radio propagation channel. Our study includes measurements of wideband frequency response, time delay spread, and distortion introduced into a 20 MHz wide digitally modulated signal. We describe the experimental set-up and the measurement results for data collected in representative structures. Finally, we discuss how a combination of propagation metrics provides a better classification of different propagation channel types than does use of one metric alone in these building penetration scenarios.
