Experimental UWB channel characterization on fire scenarios in confined environments

Firefighters should face to different situations during fire extinction. Usually, they demand sensing and location applications to improve its safety, particularly for confined environments. UWB communications have been widely investigated for high resolution positioning and sensing applications due to its unique characteristics. In this work, the effect of fire and combustion on UWB propagation inside a metallic container is investigated. Initial results shows that temperature does not affect the UWB path loss while this parameter improve at the end of the fire due to the reduction of combustion materials.
