Through-Wall Propagation Measurements

Abstract

The propagation of signals for ultra wide band (UWB) systems is analyzed. Signals can be substantially affected due to electromagnetic wave propagation through walls or similar obstacles. New experimental results and numerical simulations for frequency band from 4 to 8 GHz are analyzed and compared. That is briefly compared with the time domain experiments, which have been performed using very short pulses. Experiments performed for frequency and time domains demonstrated that the numerical simulations, which are very fast, could be reliable, when suitable wall parameters are used. Some questions concerning electromagnetic compatibility (EMC) are briefly mentioned.
