Measurement of mobile radio propagation channel in ruins

Within a running project, I-LOV, wireless communication channel model for mobile communications is developed based on measurements in reconstructed disaster and salvage scenarios. Due to complex environment in ruins, great multipath interference can take place, which strongly impacts communication quality and localization accuracy. Besides numerous measurements investigated in environments such as urban, outdoor-to-indoor or indoor, only a few are in ruins. This paper presents the first results of channel propagation measurements under collapsed buildings at GSM 900 and GSM 1800 bands. Measurement campaigns were performed in two typical collapsed structures: stratified and chaotic rubbles. The statistical properties of path-loss (PL) and RMS delay spread (DS) are reported.
