Stochastic path loss model in 5П network deployment scenarios: a study based on 3GPP TR 38.901

The fifth-generation (5G) and beyond networks will utilize radio frequencies in the terahertz spectrum, enabling extremely high data transmission rates. However, signal loss may occur when signals pass through obstacles, making it crucial to simulate signal propagation using stochastic geometry and apply up-to-date models for signal attenuation. The 3GPP TR 38.901 specification includes models that describe signal attenuation in various 5G network scenarios using empirical formulas. Nevertheless, simpler formulas are typically employed to create models based on stochastic geometry. The authors present the cumulative distribution function for path loss at random user locations according to the scenarios described in 3GPP TR 38.901. In numerical examples, it is shown that the difference in values with the simplified formula can be significant and lead to underestimation of the network's capacity.
