The transcript below shows real questions from this paper (OCR). Common themes include: [Answer all the questions (10 marks each; 4x10=40)]; a) Write the binary form of the generator polynomial G(x) = x* + x + 1 and explain the meaning of each bit in relation to the polynomial terms. Then explain the CRC (Cyclic Redundancy Check) mechanism for error detection in communication systems by addressing the following: (7 Marks) [CLO-2, L2] i. Outline CRC implementation using shift registers and feedback paths. ii. Describe the role of XOR operations in generating the remainder. b) Analyze how the selected polynomial supports transmission error detection and how the receiver verifies the frame to decide whether it should be accepted or discarded. (3 Marks) [CLO-2, L4]; A coastal disaster-resilient university campus is being planned to support digital student ID verification, smart classroom connectivity, campus surveillance, emergency warning systems, free Wi-Fi in open areas, inter-building broadband links, and backup communication during cyclones. The campus authority must select appropriate mobile generations (1G to 5G) and wireless technologies such as WiMAX, Bluetooth, Wi-Fi, Li-Fi, and Satellite to ensure uninterrupted, secure, and efficient communication across the campus. a) Identify any two mobile communication generations from 1G to 5G that would be most suitable for this university campus project. For each one, mention one important feature and one practical campus use. Then, using your knowledge of wireless and mobile communication, select suitable technologies for the following services: free open-area internet access, student ID verification at entry/control points, smart classroom high-speed indoor data transfer, inter-building connectivity, and emergency backup communication during cyclones. (7 Marks) [CLO-3, L3] b) Compare any two wireless technologies from WiMAX, Bluetooth, Wi-Fi, Li-Fi, and Satellite in terms of coverage area, speed, and suitable application for the campus communication system. (3 Marks) [CLO-2, L4].
