UMTS/HSPA

Atoll was the first UMTS network planning software on the market. Since then it has stayed ahead of the competition with continuous improvements made through close cooperation with GSM, UMTS, and LTE operators.

Atoll 3.1 supports integrated network planning for GSM/UMTS/LTE radio access technologies. 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 the planning and analysis of multi-technology networks.
