Atoll was the first UMTS network planning software on the market in 2000. Since then, it has stayed ahead of the competition with continuous improvements through close cooperation with GSM, UMTS, and LTE operators.


Atoll supports integrated network planning for 3GPP (GSM/UMTS/LTE/NB-IoT) and 3GPP2 (CDMA/LTE/NB-IoT) multi-RAT networks. It features a multi-technology network database, a unified traffic model, a combined Monte Carlo simulator, and a multi-RAT ACP (Automatic Cell Planning) module. Atoll provides operators with a comprehensive and evolutionary framework for planning and optimising multi-technology networks including small cells, integrated Wi-Fi, and IoT.
