Why Atoll
The industry standard for radio planning and optimisation
Atoll provides operators and vendors with a powerful and unique framework for designing and optimising indoor and outdoor radio access networks, from standalone deployments to enterprise-wide server-based configurations.
Prediction and measurement-based planning
Combine predictions with live-network data — KPIs, UE/cell/MDT traces and crowdsourced data — to model traffic evolution, identify hot spots, steer site selection and drive the AFP and ACP algorithms.
Integrated in-building and outdoor modelling
The Atoll In-Building module brings indoor design into the same framework: floor plans and building elements, indoor propagation, equipment installation layouts and automatic bills of materials.
In-built customisation capabilities
In-built task scripting and integration capabilities enable data- and service-level integration, letting operators streamline network planning and optimisation processes end to end.
Network lifecycle

Use cases
Where Atoll One is deployed
Smart factory
A car plant runs its own private LTE network for production lines, connected tools and quality control. Atoll One imports AutoCAD DWG or BIM IFC data to model walls, floors and pillars with real materials, then places indoor antennas and small cells to remove coverage gaps and interference zones.
Airport
An outdoor LTE network covers runways and taxiways but not terminals, hangars and indoor facilities. Atoll One combines outdoor and in-building DAS modelling in a unified simulation, so planners assess indoor and outdoor coverage together and keep performance consistent across the whole airport complex.
Mine
Terrain, an excavated pit, underground tunnels and remote installations make mining the toughest scenario. Atoll One models small base stations inside the pit, radiating cable and active DAS in tunnels, and multi-hop microwave backhaul — from open sky to underground, in one project.
Utilities
Utility networks span distributed grid infrastructure across wide areas. Atoll One models long-range coverage, backhaul links and critical substation sites so that operational telemetry and control traffic keep their availability targets.
Railway depots
Depots and stations need private LTE or 5G for operations alongside GSM-R or FRMCS infrastructure. Atoll One handles multi-technology projects, dense metallic environments and indoor/outdoor transitions in a single model.
Engineering companies
Atoll One installs in minutes and can ship with the GIS data a project needs — ideal for private mobile operators and engineering companies working project by project for industrial and infrastructure customers.
