The Atoll NB-IoT module supports the 3GPP NB-IoT standard and includes extensive cellular IoT functions. Atoll offers a powerful platform for operators to plan and optimise NB-IoT networks as independent deployments or on top of LTE. Atoll is being used by a large number of IoT operators worldwide.

Atoll supports integrated network planning for 3GPP (GSM/UMTS/LTE/NB-IoT) and 3GPP2 (CDMA/LTE/NB-IoT) 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.

Network Modelling
