| | Atoll 3.5 | Atoll 3.6+ (5G Ready) | | :--- | :--- | :--- | | 5G NR Support | No (Planning only) | Full (FR1/FR2) | | Massive MIMO | Basic (8T8R) | Advanced (64T64R beamforming) | | Memory Footprint | Low (2–4 GB RAM) | High (16+ GB RAM) | | License Cost | Legacy (Lower for maintenance) | High (New modules) | | Bug stability | "Rock solid" | Frequent patches |

For operators who do not need millimeter wave (mmWave) or 5G Standalone (SA) slicing, Atoll 3.5 remains a faster, cheaper, and perfectly adequate tool for 4G optimization. Imagine a Tier 2 operator in Southeast Asia with 2,500 LTE sites. In 2018, they used Atoll 3.5 to solve a capacity crunch in Jakarta. atoll 3.5
