/* SBR Analysis of the Manhattan Scene with a Vertical Dipole Transmitter */
:<math> P_R = P_T G_T G_R \left( \frac{\lambda_0}{4\pi R} \right)^2 = 29.14dBm + 20log_{10}\left( \frac{0.125}{4\pi(28.5)} \right) \approx -40dBm</math>
 
The table below summarizes the computational statistics associated with the SBR simulation performed earlier:

The SBR simulation was performed on a ASUS laptop computer with an Intel i7-4860 HQ processor with eight cores. The laptop features 32GB RAM memory. Due to the complexity of the geometry of many buildings, the mesh generation task took a sizable amount of time. The table below shows the time spent by the CPU for the mesh generation and SBR ray tracing portions of the total simulation time:
