Question 4 (a) An antenna of gain 50 dB operating at 16 GHz is aimed at a satellite 30,000 km away. The satellite has an antenna of gain 40 dB which transmits signal back to earth at 15 GHz. If the power transmitted by the satellite is 3 W, can the earth station receive the signal when the smallest signal it can detect is 10 pW? State the assumption(s) made. C4/CLO2/PLO2 (15 marks) (b) Recommend the maximum frequency for a 10 km link if the path loss is not to exceed 112.45 dB. C5/CLO2/PLO2 (5 marks) (c) Design a radio communication link with a visual horizon of 50 km using space wave propagation. C6/CLO2/PLO2 (5 marks)
