GSM/GPRS/EDGE

Atoll 3.1

Atoll GSM/GPRS/EDGE module provides a comprehensive and accurate modelling of voice and data services, including full support of HCS and frequency hopping.

Optimised multi-resolution predictions and interference calculations facilitate planning as well as optimising mature networks that have a large number of sites and country-wide coverage.

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 multitechnology networks.
