This paper presents measurement results and initial physical modeling of the radiowave propagation phenomena in the presence of fire using Pinus Pinaster fuel heaps. To this extent, this paper reports on small-scale measurement trials carried out at 700 MHz on Pinus Pinaster fuel bed on fire and subsequent validation of simulation results of the propagation phenomena behavior based on the intertwined use of both Fire Dynamics Simulator and the Cold Plasma Model. Excess attenuation of up to 1.52 dB was observed in measured results, which is thought to be critical considering it is a small-scale fire scenario composed of a 1 x 1 m 2 with 0.6 kg of pine needles.
