Anechoic-chamber measurements of through-wall propagation

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 of anechoic-chamber measurements and numerical simulations for frequency band from 4 to 8 GHz are analyzed and compared. That is briefly compared with the previous experiments, performed in real scenarios (walls between laboratories or offices) in various frequency bands and time domain measurements, which have been done 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.
