With GSM networks carrying more traffic than most technologies put together, it becomes critical for a good cell planner to have a wide set of skills and knowledge encompassing radio propagation effects, GSM air interface protocols, prediction models and tools, traffic dimensioning, capacity and coverage enhancement methods, optimization techniques as well as the ability to interpret system information. The GSM cell planning course addresses these requirements of a modern GSM cell planner through key learning points which are reinforced through practical demonstrations, tutorial exercises and case studies.

Expected Rccomplishments

  • Understand dimensioning of traffic and control channels using Erlang traffic theory
  • Design frequency plan taking into account co-channel /adjacent channel interference.
  • Explain how uplink and downlink coverage is balanced.
  • Conduct link budget calculations.
  • Make coverage predictions based upon theoretical and empirical models.
  • Identify techniques adopted in GSM to enhance coverage and capacity.
  • Identify transmission problems and mitigating techniques.
  • Examine key radio network features used for network optimization.
  • Design a specimen radio network-using cell planning guidelines.
