### Campaigns of Measurements  
An experimental campaign of measurements has been performed in the real scenario located in Monterrey, Mexico, to validate the proposed simulation algorithm. Figure 6 presents the schematic view of the deployed equipment. For the transmitting part, a signal generator SMB100A from Rohde & Schwarz up to 20 GHz has been used. A frequency multiplier FDA-K/28 from Farran Technologies has been connected to the signal generator to increase the transmitted signal up to 28 GHz. Then, a Ka-band omnidirectional antenna Model SAO-2734030345-KF-S1, from SAGE Millimeter, Inc. has been used. For the receiving part, a Ka-band omnidirectional antenna has been used, Model SAO-2734033045-KF-C1-BL from SAGE Millimeter, Inc., equipped with a low noise amplifier (LNA) of 30 dBi. Finally, the received power has been measured with a portable spectrum analyzer N9952A 50 GHZ FieldFox from Keysight Technologies. A collage with real pictures of the scenario, with the deployment of the employed equipment, as well as the surroundings of the considered scenario can be seen in Figure 7. The transmitter and receiver antennas have been placed at 1.5 m height with the aid of a tripod constructed from wood and nylon materials (AT-812 Antenna Tripod from Com-Power Corporation).  
The campaign of measurements was performed in a common business day in the morning hours with medium vehicles' density along the road. The transmitter antenna was placed at 1.5 m height on the sidewalk by the roadside. The specific transmitter location can be seen in Figure 8 depicted with a red triangle in the considered scenario. Measurements were performed along the same sidewalk as the transmitter, with a separation distance between them of 1.20 m (with a total of 31 points depicted as P1 to P31 in Figure 8), and across the sidewalk with a separation distance between them of 2 m (with a total of 15 points depicted as \(P_{c}1\) to \(P_{c}15\) in Figure 8). The spectrum analyzer was set up with a center frequency of 28 GHz and 100 MHz bandwidth, with a measurement time at each point of 60 s. Received power was measured at each point with the highest peak (Max-Hold function in the spectrum analyzer), to compare with equivalent continuous wave operatio
