Atoll 3.5 -

| | Best Use Case | Frequency Range | | :--- | :--- | :--- | | Standard Propagation Model (SPM) | General macro-cell (calibrated) | 150 – 3500 MHz | | ITU-R P.526 | Diffraction (hilly terrain) | Any | | WINNER II | 4G MIMO/ Small cells | 2 – 6 GHz | | COST 231 Hata | Legacy urban/Suburban | 1500 – 2000 MHz |

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

In the world of Radio Frequency (RF) planning and network simulation, names like Atoll have been synonymous with precision. For over two decades, Forsk’s Atoll has been the gold standard for mobile operators, equipment vendors, and consultants. While the tech world obsesses over the latest "Atoll 3.6" or the cloud-native "Atoll 3.7," the Atoll 3.5 release remains a watershed moment—and for many legacy networks, it is still the benchmark. | | Atoll 3
