Atoll - GSM/TDMA/GPRS/EDGE Features

GSM/TDMA/GPRS/EDGE Features

Atoll includes state-of-the-art GSM/GPRS/EDGE features that provide comprehensive and accurate modelling of voice and data services, including full support of HCS and frequency hopping. Multi-resolution predictions and optimised interference calculations facilitate planning as well as optimising mature networks that have a large number of sites and country-wide coverage.

Atoll also includes advanced 2G/3G co-planning features that have been developed in partnership with major wireless operators.
