In this paper the propagation of radio waves at 2.4 GHz in NLOS conditions has been studied. The study was carried out using two transmitters operating on different standards: 802.11g (D-Link) and 802.11n (TrendNet). The experiments were carried out under different scenarios in order to investigate the effect of the walls on signal propagation. Experimental results were processed using statistical methods and were compared with "Log-distance" and free space models and with the network simulation programme "Aerohive online planner" results. A new signal prediction model, which allows predicting signal propagation depending on the number of walls, was created.
