UMTS/HSPA

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

Atoll version 2.8 includes support for HSPA+ and MIMO.

Atoll 2.8 includes a new GSM/UMTS interference analysis feature that helps operator to analyse and plan GSM and UMTS deployments in the same frequency bands.
