Atoll was the first UMTS network planning software on the market. Since it has stayed ahead of the competition with continuous improvements through close cooperation with GSM, UMTS, and LTE operators.
Atoll supports integrated network planning for3GPP GSM/UMTS/LTE multi-RAT networks. It features a multi-technology network database, a unified traffic model, and a combined GSM/UMTS/LTE Monte Carlo simulator that provide operators with a comprehensive and evolutionary framework for planning and analysing multi-technology networks. Atoll can model the traffic-related aspects of multi-technology networks and dynamically spread and offload traffic between technology layers. Wi-Fi offloading and HetNets are modelled following the same unified traffic approach in Monte Carlo simulations.
