Atoll includes a powerful and flexible GSM AFP module that is being used by a large number of operators worldwide. It is based on sophisticated optimisation techniques and includes advanced features such as combined automatic/interactive frequency planning and optimisation of TRX allocation vs. interference conditions.


The Atoll GSM AFP (Automatic Frequency Planning) module allows combining multiple interference matrices generated from predictions and OSS measurement data.


Atoll also includes dedicated LTE, WiMAX, and Wi-Fi AFP modules that support technology-specific allocation features.
