Seamless Indoor & Outdoor Coverage Design With Atoll’s In-Building Module
As operators across Australia and New Zealand accelerated their 4G and 5G deployments, one issue became increasingly visible:
customers were still experiencing poor indoor performance even when outdoor coverage was strong.
Skyscrapers, complex floor layouts, shopping centres, and modern construction materials all contributed to inconsistent indoor coverage.
The Challenge
Growing customer complaints about weak indoor 4G/5G signals despite good outdoor macro coverage
Lack of a unified planning environment to design both outdoor macro/small cells and in-building systems
High cost and inefficiency from using multiple separate tools for DAS, small cells, and outdoor planning
Difficulty predicting performance across transitions between outdoor and indoor layers
The Solution
Operators turned to Forsk’s Atoll platform, supplied and supported regionally by TeleResources. By combining the Atoll Outdoor modules (macro & small-cell planning) with the Atoll In-Building module, operators could:
Use one planning environment for outdoor and indoor network design
Import floor plans, material libraries, and 3D building models to simulate indoor propagation accurately
Design DAS, small cells, and in-building solutions in the same workspace as the macro network
Seamlessly evaluate handover, transition zones, and combined coverage layers
Reduce engineering effort by eliminating the need to export, merge, or reconcile data across separate tools
The Impact
The integrated approach delivered immediate value:
Unified outdoor + indoor planning improved design consistency and engineering efficiency
More accurate indoor predictions, closely matching post-deployment measurements
Reduced redesign cycles and site revisits
Faster rollout of enterprise 5G solutions (offices, hospitals, retail centres, hotels)
Significant improvements in customer experience and retention
A senior RF engineer commented:
Using Atoll for both macro and in-building planning streamlined our entire workflow. We could design everything—from street-level 5G to multi-floor indoor coverage—in one tool.
Powering the future of mobility with reliable EV charging solutions.
