2. A communications satellite is 36,000km from Earth and there is a half-duplex radio link between a station on Earth and a receiver on the satellite. The radio link has a bandwidth of 50,000 bits per second and the radio signal travels at the speed of light (3 x 108 m/s). A 3,000 bit message is sent to the satellite and there is a total of 1 second of delay for queuing and processing before that transmission begins. a) Calculate the total time required for delivering the entire message to the satellite over this radio link. b) Calculate the bandwidth x delay product for the radio link from the station to the satellite. c) Calculate the utilization of this radio link during the time this message is transmitted. 2.
