RF  Planning


In the context of mobile radio communication systems, RF Planning is the process of assigning frequencies, transmitter locations and parameters of a wireless communications system to provide sufficient coverage and capacity for the services required. The RF plan of a cellular communication system has two objectives: coverage and capacity. Coverage relates to the geographical footprint within the system that has sufficient RF signal strength to provide for a call/data session. Capacity relates to the capability of the system to sustain a given number of subscribers. Capacity and coverage are interrelated. To improve coverage, capacity has to be sacrificed, while to improve capacity, coverage will have to be sacrificed

The RF Planning process consists of four major stages.

  • Phase (1) Initial Radio Link Budgeting
  • Phase (2) Detailed RF Propagation Modelling
  • Phase (3) Fine Tuning & Optimisation
  • Phase (4) Continuos Optimisation
