5G NR

Atoll 5G NR module allows operators to plan and optimise 5G networks based on the 3GPP specifications. Atoll supports both 5G NR NSA (Non Standalone) and 5G NR SA (Standalone) modes.

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 evolutive framework for the design and deployment of 5G networks. Since early 2017, major operators and vendors have been using Atoll for the very first deployments of 5G wireless access networks.

 

Atoll supports integrated network planning for 3GPP and 3GPP2 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.
