Radio network planning of a cellular network

  • Cellular concept and reuse of frequencies.
  • Concept of cell pattern and distance reuse.
  • Propagation in mobile radio environment: phenomena and effects (mask effect, vegetation impact, multiple paths and Rayleigh fading, Delay Spread and Doppler), interference, noise, …
  • Propagation models: multi-floors and multi-layers model, Pathloss, empirical and exact models, Okumura-Hata model, Walfish-Ikegami model, Deygout model, multi-rays model, …
  • Propagation model tuning: procedure, tools, implementation and validation.
  • Basic concepts of cellular network antennas: main characteristics, types, diagram, …

Radio Ressources Engineering

  • Quality of service concept: reminders on perception and evaluation by operators and subscribers.
  • Laws of Erlang and approximations: origin of the Erlang B, approximation of the general Erlang law, Erlang C law and formulas.
  • Application exercises: GSM channel sizing for traffic (TCH) and signaling (SDCCH).
  • Dimensioning of radio resources (TCH, SDCCH, number of TRX, DPCCH and DPTCH …).
  • Dimensioning techniques: theory of traffic dimensioning packet data, traffic patterns, approximations for traffic in a cellular network.
  • Exercises: examples of GPRS and EDGE networks.
  • Dimensioning of nodes: Dimensioning of BTSs and A-bis links, Dimensioning of BSCs, Parameters of a BSC (processor load, number of TRX and maximum BTSs, capacity of signaling and traffic links, …).

Radio planning coverage and optimization of a cellular network

  • Life cycle of a cellular network: project identification and dimensioning, planning and business plan, implementation and network tuning, optimization and evolution, densification and introduction of new services.
  • TDMA budget link: standard, principle theory and examples of link budget, with and without a repeater.
  • Radio network planning tools: standard, utility, inputs, functionalities, digital maps (DTM, Clutter, Ortho Image, Vectors, …).
  • AFP: complexity and number of possible solutions.
