| Problem | Likely Cause | Atoll 3.5 Fix | | :--- | :--- | :--- | | | Wrong SPM coefficients, or clutter heights missing. | Perform model tuning; set proper Clutter Loss values (e.g., +15 dB for dense urban). | | Monte Carlo fails to converge | Insufficient number of users or low max iterations. | Increase Number of Snapshots to 200+, or reduce Convergence Threshold to 0.01 dB. | | Slow prediction on large projects | Too many clutter classes (e.g., >20) or fine raster resolution. | Merge similar clutter types (e.g., “forest dense/light”); use 20m or 50m resolution for regional scans. | | 5G results don’t match drive test | Beamforming model not calibrated. | Use the Ray-tracing option if available, or adjust Beam Gain map manually. |
He opened the new interface, noticing the small, tactile changes—the ability to finally close inactive tabs with a click of his mouse wheel. But the real challenge lay deeper, in the massive MIMO antenna modeling. The city’s high-rises were becoming signal-hungry giants, and the old 4G models were starving. atoll 3.5
As network architectures evolve from purely terrestrial setups to complex, multi-technology environments, planning tools must keep pace. Atoll 3.5 serves as a critical bridge in the Forsk software roadmap, refining the user experience for 4G/5G rollout while laying the groundwork for future 6G and Non-Terrestrial Network (NTN) integration. | Problem | Likely Cause | Atoll 3
