[Solved]E Two Base Stations 40km Apart Connected Microwave Data Link Data Sent Across Link 800 Byt Q37232384

e) Two base stations are 40Km apart and are connected by a microwave data link. Data is sent across the link in 800 byte frames and the link operates at a data rate of 80Mbps. Assuming the link has a bit error rate of 4 x 105, and a velocity of propagation v -3 x 10% m/s, determine the link utilisation efficiency using the following protocols: (0) Idle RQ (ii) Continuous RQ with a send window buffer k-2; (iii) Continuous RQ with a send window buffer k-200; (iv) Suggest a way to increase the link utilisation of Selective repeat RQ [6 Marks] 3 EMankel 12 Marks] scheme. Discuss potential disadvantages of such approach. [4 Marks] Show transcribed image text e) Two base stations are 40Km apart and are connected by a microwave data link.
