Question

5.5) A 1.8 GHz transmitter and a receiver are separated by 6 km. A sharp edge absorbing screen is inserted below and normal to the direct path between transmitter and receiver, which is 2 km from the transmitter. How closely can the edge of the screen approach the direct path and not introduce excess path loss? 5.6) If in the communication system described in Problem 5.5, the screen is inserted so that its edge is 20 m above the direct path, calculate the excess path loss and the total path loss.
