We empower our division to increase the throughput in fiber rollout almost tenfold (to over 2 million per year) with a stable team size. To make this happen, we digitize and automate the entire network design and network planning process chain as much as possible.

  • 3D visualization of construction areas
  • AI-based classification (surface, network infrastructure…)
  • Automated generation of network infrastructure
  • Service-based, generic interfaces for measuring devices
  • Support for documentation and billing

We are currently strongly shifting toward cloud-based deployments, while our application stack includes both open source and proprietary products.
