Atoll includes an advanced multi-technology Automatic Cell Planning (ACP) module that provides integrated network optimisation functions in the standard Atoll user interface. All ACP data and results are stored in the Atoll project files and databases.

The seamless integration of the radio planning and optimisation features provides a direct return on investment from using the Atoll ACP. Atoll ACP is available for GSM, UMTS, LTE, CDMA, WiMAX, Wi-Fi, and IoT/LPWA technologies.

It supports combined GSM/UMTS/LTE and CDMA/LTE optimisation together with small cells and Wi-Fi.
