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, 4G LTE, 4G NB-IoT, 2G GSM, WiMAX, and Wi-Fi AFP modules that support technology-specific allocation features.


5G NR Automatic Frequency Planning (AFP)

The Atoll AFP module, in conjunction with the Atoll 5G NR module, helps mobile operators streamline key 5G planning activities such PCI and RSI planning.

  • Automatic frequency carrier allocation
  • Automatic PCI allocation considering PSS, SSS, PBCH DMRS, and UL DMRS collisions
  • Automatic PRACH RSI allocation
  • User-definable constraints and editable cost function
    • Direct neighbours
    • Indirect neighbours
    • Second-order neighbours
    • Inter-cell handover KPIs
    • Predicted and measured interference matrices
    • Inter-cell distance
  • Support for multi-carrier and multi-band networks

4G LTE/NB-IoT Automatic Frequency Planning (AFP)

The Atoll AFP module, in conjunction with the Atoll LTE module, helps mobile operators streamline key 4G planning activities such as PCI and RSI planning.

  • Automatic frequency channel allocation
  • Automatic PCI allocation considering PSS, SSS, RS, ULDMRS, and PCFICH collisions
  • Automatic NPCI allocation considering NPSS, NSSS, NRS, UL NDMRS
  • Automatic PRACH RSI allocation
  • User-definable constraints and editable cost function
    • Direct neighbours
    • Indirect neighbours
    • Second-order neighbours
    • Inter-cell handover KPIs
    • Predicted and measured interference matrices
    • Inter-cell distance
  • Support for multi-carrier and multi-band networks

2G GSM Automatic Frequency Planning (AFP)

The Atoll AFP module allows combining multiple interference matrices generated from predictions and OSS measurement data.

The Atoll AFP module, in conjunction with the Atoll GSM module, helps mobile operators streamline key 2G planning activities such as frequency and BSIC planning with and without frequency hopping, as well as network dimensioning.

  • Modelling of frequency bands, carrier layers, and border constraints
  • Support for vendor equipment constraints/features
  • Generation, import, edition, storage, and combination of interference matrices
  • User-definable constraints and editable cost function
  • 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

 

WiMAX AFP

  • Automatic frequency channel allocation (full and fractional frequency planning)
  • Automatic preamble index allocation
  • Automatic downlink and uplink permbase allocation
  • User-definable constraints and editable cost function
    • Direct neighbours
    • Indirect neighbours
    • Second-order neighbours
    • Predicted and measured interference matrices
    • Inter-cell distance
  • Support for multi-carrier and multi-band networks

Wi-Fi AFP
