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, that allows a complete integration of combined 4G/5G network planning.
