The above figure shows a maximum receiver power of -42dBm. To run a quick sanity check on the simulation results, consider the fact that the transmitter and receivers are placed 30m and 1.5m above the ground elevation, respectively. Therefore, the minimum distance between the transmitter and the line-of-sight (LOS) receivers is R<sub>min</sub> = 28.5m.
:<math> P_R = P_T G_T G_R \left( \frac{\lambda_0}{4\pi R} \right)^2 = 30dBm + 2.15dB + 0dBm + 20log_{10}\left| ( \mathbffrac{ \hat0.125}{u}_T 4\cdot \hat{u}_R pi(28.5)} \right|^2 ) </math>
