Atoll 3.5 [UPDATED]

| Domain | Application | |--------|--------------| | Mobile operators | LTE-A capacity expansion, CA deployment planning | | Regulators | Spectrum sharing analysis, coverage obligation verification | | Broadcasters | DTT (Digital Terrestrial TV) interference studies | | Enterprises | Private LTE/NB-IoT network design (factories, ports, mines) |

Forsk officially ended mainstream support for Atoll 3.5 in 2020. However, due to its reliability, many government defense sectors and utility companies (private LTE networks) still run it. It is no longer available for purchase as a new license, but existing perpetual licenses are highly sought after on secondary markets.

The 3.5 update brought significant optimizations to the Maplink module, which used live drive-test and Automatic Cell ID (UCID) data to calibrate predictions. The algorithm for "Ray Tracing" in urban canyons saw a 15% improvement in accuracy compared to version 3.2, particularly for indoor propagation. atoll 3.5

Atoll 3.5’s Interference Matrix is invaluable for:

For large network operators managing 10,000+ sites, manual planning is impossible. Atoll 3.5 solidified its COM (Component Object Model) API, allowing engineers to write Python or VB scripts to automatically: | Domain | Application | |--------|--------------| | Mobile

One of the most beloved features of this version is the ability to run GSM/UMTS/LTE co-existence studies. If you were refarming 900MHz spectrum from 2G to 4G, Atoll 3.5 allowed you to model the impact on legacy call drop rates while optimizing new LTE throughput—all in the same project.

If using a version with 5G support:

Unlike earlier versions that treated LTE simplistically, Atoll 3.5 introduced granular support for 3GPP Release 10 and 11. Key capabilities included:
