EEC 620: Second Semester Examination, University of Buea, College of Technology, Instructor Dr. Ningo, June 2022: Question 1, characterizing the wireless channel and its propagation effects (multipath, fading, shadowing, Doppler spread) between two points in Bonanjo (a dense commercial district) versus Japoma (an open stadium area) from 6AM to 6PM, with and without a football match, how cell structure would adapt via cell breathing if continuously redesigned, and comparing cell sizes/propagation mechanisms at noon; Question 2, choosing the appropriate Lee-model path-loss exponent for each environment from a given parameter table, and explaining why the Lee and Hata models predict different median received powers (-97.1 dBm vs -105 dBm) at 10 km for the same environment and distance.
