Atoll was the first LTE network planning software on the market. Today, Atoll offers a powerful platform for operators to plan and optimise LTE-A Pro and 5G NR networks.

Atoll supports integrated network planning for 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.
