Now open the simulation run dialog and click the {{key|Settings}} button next to the simulation engine type drop-down list. This opens up [[EM.Terrano]]'s Ray Tracing Engine Settings dialog. Uncheck Uncheckmark "Include edge diffraction" checkbox and a new SBR analysis. You will see that there is no reception behind the buildings.

To improve the reception, you can bring the transmitter to the edge of the plateau. Keep in mind that to move a transmitter or receiver, you need to move their associated based point sets. Change the coordinates of the base point "TXP" to X = Y = 30mm. Keep the original Z-coordinate of 10m. Now make sure to checkmark "Include edge diffraction" checkbox and run a new SBR analysis of the scene and visualize its coverage map. You will see that the valley region now gets considerable reception.
