0 20m 2m 8m 50m The above figure shows an access point and a laptop in a 20mX50m room communicating with one another. Communication between the terminals is taking place through five paths: the direct path and four paths reflected from each wall. The reflection coefficient from the walls is 0.7 and each reflection causes an additional 180 degrees phase shift. The access point is located in 2m distance from the left wall and 8m distance from the lower wall of the room. The laptop moves from 1m of the access point towards the right hand side wall until it is at 2m distance from the right wall. 5. Use MATLAB to plot the RSS versus distance for Im
