Abstract: This paper presents certain TETRA system parameter analysis and advantages of this radio communication system within the area of public safety services exploitation. We conducted receiving signal measurement along the high burdened road section from Belgrade to Lazarevac, monitoring the signal level originating from three surrounding base stations. Conducted measurement scenario is simulated and analyzed in terms of propagation prediction using an adequate software package. Results processing and analysis was done using the HTZ warfare software package. The correlation between the measured values and the values obtained by propagation prediction is depicted in detail.

Keywords: TETRA, HTZ warfare, prediction, measure.
