LTE

In 2008, Atoll LTE was the first LTE network planning software available on the market. It has since then been used on a number of projects worldwide. Atoll 3.1 is a comprehensive framework for operators who need to plan evolution towards LTE. It allows planning and analysing integrated GSM/UMTS/LTE and CDMA2000/LTE networks.

This module is the result of a strong R&D program in 4G technologies which Forsk is conducting with strategic partners including world-leading equipment vendors and operators.
