Atoll TD-SCDMA has been developed in partnership with major players in the TD-SCDMA scene in China, and is the most widely used TD-SCDMA planning software on the market.

Atoll supports TD-SCDMA/TD-LTE co-planning, and allows TD-SCDMA operators to plan and analyse the evolution of their networks towards 4G TD-LTE.
