TD-SCDMA

Atoll TD-SCDMA has been has been developed in partnership with major players in the TD-SCDMA
scene in China, and is the most advanced and 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 TD-LTE. Atoll also supports 2G/TD-SCDMA co-planning.
