Atoll includes powerful and flexible AFP (Automatic Frequency Planning) modules based on sophisticated optimisation techniques that are being used by a large number of operators worldwide.

Atoll includes dedicated 5G NR, LTE, NB-IoT, GSM, WiMAX, and Wi-Fi AFP modules that support technology-specific allocation features.

    • Second-order neighbours
    • Inter-cell handover KPIs
    • Prediction-based or imported interference matrices
    • Inter-cell distance
  • Support for multi-carrier and multi-band networks

LTE/NB-IoT AFP

  • Allocation of frequency hopping parameters (MAL, HSN, MAIO)
  • Combined automatic/interactive frequency planning on map (IFP)
  • Optimisation of TRX allocation vs. interference conditions
  • BSIC planning
  • Intermodulation interference reduction
