Tailored Network Optimization –

Step-by-step approach avoids errors and unnecessary costs

Analysis first, then the solution

After performing a radio survey of the current situation, it becomes clear where coverage gaps exist.
But only a detailed analysis of the root causes and a customized network optimization
will ensure stable and comprehensive indoor connectivity.

Weak mobile signals inside buildings are typically caused by physical barriers:
reinforced concrete, modern thermal insulation glass, metallic façades, or electromagnetic interference
block radio waves. In addition, structural factors like building depth, large surface areas, or interference from in-house technology
(e.g., elevators, server rooms, fire safety systems) can reduce signal strength.

Did you know?
Even a single fire door or a metallic-coated glass pane can cause a signal loss of over 20 dB —
which means virtually no reception.

The first step towards better network coverage: We plan your individual radio measurement in the building.

Step 2:
Analysis and evaluation of mobile network infrastructure in your buildings and facilities

Where is the signal weak – and why?

Our analysis reveals weak points and prepares the ground for targeted optimization – with results that are measurable, reliable, and easy to understand.

  • Red = poor coverage
  • Yellow = moderate coverage
  • Green = good coverage

Only those who know the gaps and their causes can close them:
Our network assessment, based on a wide range of measured parameters, lays the foundation for a tailored mobile connectivity solution.

Space Master GEO Integrated for maximum transparency:
We carry out our evaluations using SpaceMaster GEO – the powerful platform for geo-referenced analysis and visualization of mobile network measurement data.

  • Intuitive map view with zoom, layers, and comparison functions
  • Clear display of measurements as heatmaps, signal diagrams, or cell ID mappings
  • Exportable reports for tenders, internal communication, or operator coordination

Your benefit:
Instead of abstract numbers, you receive a solid decision-making basis – clearly presented and ready to use.

Step 3:
Tailored mobile connectivity consulting – focused on your requirements

Every building and every usage scenario places unique demands on mobile coverage.
In our personal consultation, we analyze your specific needs – from technical and organizational aspects to economic feasibility.
This allows us to design a solution that fits your exact situation.

  • Improve overall coverage – achieve seamless mobile signal throughout the entire building
  • Target specific areas – e.g., entrances, conference zones, underground garages
  • Include all networks – ensure reliable reception from all major providers
  • Prioritize a specific operator – e.g., preferred business partner or enterprise contract

Whether poor reception in sensitive areas, emergency communication requirements, or complex architectural conditions –
we support you from initial needs assessment to implementation.
Our experience with office buildings, logistics centers, hospitals, educational institutions, and production sites
ensures that your mobile solution not only works, but also makes financial sense.

Your mobile network solution – targeted or building-wide

Band-selective or broadband: we show the options, you decide.

Depending on your needs, we provide coverage for specific areas or the entire building –
either band-selective or broadband.
We analyze the situation, you choose the solution.
Vendor-independent, technology-agnostic, and efficient.

Broadband amplification & full indoor coverage

All networks. All frequencies. Throughout the building.

For complex buildings or demanding use cases, we recommend a broadband coverage solution.
All relevant mobile frequency bands (2G to 5G) across all carriers are amplified and evenly distributed
via repeaters or DAS (Distributed Antenna Systems).

Typical application scenarios:

  • Office buildings with many workplaces
  • Hospitals, hotels, or event venues
  • Industrial sites reliant on mobile connectivity

👉 Our approach: We provide neutral, technology-agnostic consulting –
you decide which solution to implement.
