About this paper

EEC 319: First Semester Examination for EEC319, Radio Communication, University of Buea, Course Masters Dr ACHIRI and Dr MBIEDA, 04/02/2026, 2 hours. Section A (35 marks): GSM technology -- mobile station parts, BSS/NSS components and roles, HLR/VLR parameters, EIR and AuC functions, OMC types, a GSM interface block diagram, handover definition, three handoff decision strategies (NCHO/MAHO/MCHO), and four handover types (intra-cell, inter-cell intra-BSC, inter-BSC, inter-MSC). Section B (35 marks): identifying which of five given expressions is not one of Maxwell's four equations (the continuity equation, a derived consequence rather than a fundamental Maxwell equation), a normal-incidence plane-wave transmission problem at an air/dielectric (er=16) boundary (transmission coefficient, transmitted and incident E fields from a given transmitted H field), the definition of path loss, deriving the free-space path-loss formula 20log(f)+20log(d)+32.4 from first principles, reducing it to A+B*log(d) at 2400MHz, a maximum-allowable-loss range calculation, naming three propagation models and the Okumura model's applicable environment/antenna height range, and a bonus received-power link-budget calculation.
