Customer testimonials at fiberdays 2026
In Frankfurt am Main, there was ample opportunity for discussion regarding fiber-optic expansion and digital infrastructure in Germany.
Nexiga primarily showcased supporting applications related to planning-relevant geodata in the telecommunications sector—ranging from site selection and route planning to capacity assessment.

Customer Insights #1 through #4
Where is fiber-optic expansion really worthwhile?
Problem #1 of #4
Limited resources, but many potential expansion areas. Where do you start?
However, with precise address, building, and household data, areas can be evaluated very effectively using data-driven methods:
- Identify household density
- Calculate potential per expansion area
- Take competitors' price ranges into account
- Determine ROI-based prioritization
Result: Investments are directed specifically toward the areas that make the most economic sense.
Which buildings are eligible for fiber-optic expansion (NE4)?
Problem #2 of #4
Which buildings should be prioritized in the expansion plan? After all, not every building is equally cost-effective.
Detailed building information is therefore a key factor in renovation planning. Data on residential units and floors makes it possible to clearly prioritize:
- Prioritize apartment buildings with high connection potential
- Cost vs. revenue can be assessed realistically
- Material and labor costs can be estimated more accurately
Result: Greater efficiency in building development and improved cost-effectiveness.
How can construction costs be reduced?
Problem #3 of #4
How can network planning be made more efficient? After all, in detailed planning, every meter of civil engineering work counts and incurs immense costs.
However, network operators can effectively address this issue in advance by using georeferenced address and building data, as well as information on new development clusters, new construction zones, or parcels of land:
- Plan routes accurately
- Forming clusters efficiently
- Optimize network sizing
Result: Lower construction costs, more efficient planning, faster rollout.
How can we achieve the required connection rate?
Problem #4 of #4
Reaching new target groups—but where? The success of a development project hinges on pre-marketing. Before construction even begins, it’s important to secure approximately 30–40% of the units.
By leveraging data on the number of households, socioeconomic information, and insights into communication and consumption patterns, providers can better narrow down their target audiences with the goal of:
- Field sales only in promising areas
- Deliver targeted campaigns
- Focus on buildings with high potential
Result: Higher take-up rates and faster decision-making processes are achieved for the expansion. Waste coverage is minimized.
And even after the expansion, there is still potential:
As part of the redensification process, previously untapped or undecided households can be specifically targeted.
Here, too, data helps to:
- Identify buildings with a high probability of completion
- manage targeted follow-up campaigns
- to further increase the retention rate among existing customers
An added benefit: more customers using existing infrastructure—at a relatively low cost.

Relevance of house data
As always, the Nexiga house database, which provides extensive features on all identified houses in Germany, was at the center of many discussions.
-
Number of households and companies per address point
-
Parcels with detailed land use and house perimeters
-
Building type, number of floors, building use
-
Technology scores, online streaming affinity, Sinus-Milieus
-
Telecommunication types and typical usage behavior
-
Bandwidth already available for every address in Germany
-
and much more...

LoD2 - 3D building models
In general LoD2 data (Level of Detail 2) provide detailed 3D building models that take roof shapes and pitches into account, for example. These also provide a valuable basis for the precise and efficient planning and implementation of fiber optic expansion:
Planning the cable installation: Detailed building features help plan the optimal route for laying fiber optic cable. This can take into account obstacles such as buildings and other structures, enabling a more efficient installation.
Cost calculation: With precise information about the building heights and shapes, the costs for the installation can be better estimated. This includes the required length of cable and the number of connection points required.
Access points: LoD2 data can help identify the best access points for the fiber optic cables, especially for complex roof structures. This also applies to the expansion of network level 4, which starts at the house connection and extends to the junction boxes in the individual apartments or offices.
Simulation and visualization: The data makes it possible to simulate and visualize the planned installations in a 3D environment. This can help to identify and rectify potential problems at an early stage.
