Atoll allows mobile operators to plan and optimise 5G NR networks deployed in both NSA (Non Standalone) and SA (Standalone) modes, together with 4G and legacy 2G and 3G layers.

Atoll’s modular and advanced radio technology modelling capabilities, along with the support for mmWave propagation, massive MIMO, and 3D beamforming, provide operators with a complete and evolutionary framework for the design and deployment of 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 2G/3G/4G/5G networks including small cells, integrated Wi-Fi, and IoT.
