GSM boosting
tailored to your building
Concrete, steel and dense structures block mobile signal. Mercuron analyses your situation and installs a system that covers every zone — for all operators.

Modern buildings — with their reinforced concrete, metal façades and energy-efficient glazing — often act as real signal blockers. Outdoor signal from towers barely reaches the inner floors.
The result: employees who need to go outside to make a call, dropped conversations, slow data and a loss of productivity that nobody measures exactly — but everyone feels every day.
And in priority situations — fire, evacuation or a medical incident — the impact of poor coverage goes far beyond inconvenience.
How Mercuron solves it
No off-the-shelf solution — every installation is designed specifically for your building and situation.
Site survey & signal analysis
We measure the existing signal in your building and map the exact dead zones.
Custom RF engineering
Based on the analysis, we design a system with the right antenna placement and amplifier parameters.
Multi-operator coverage
Proximus, Orange, Telenet — one system covers all operators at the same time. No exclusive contracts are needed.
Professional installation
Our technicians install the system discreetly and in line with all applicable technical standards.
Validation measurement & report
After installation, we perform a validated coverage measurement and deliver a full report.
Aftercare & maintenance
One point of contact for questions, adjustments and maintenance after delivery.
What does GSM signal boosting for a building cost?
Every installation is designed for your specific building. As a guideline:
- Basic installation
from € 9,000
Around 6 antennas — for example an office, shop or restaurant.
- Large building or industrial site
€ 25,000 – € 35,000
20 or more antennas, spread over several floors or halls.
The exact price depends on floor area, number of floors, building structure and the networks required. That is why every project starts with a free coverage analysis.
Suitable for every building type
The technology behind GSM signal boosting
Modern offices, car parks and industrial halls block mobile signal because of reinforced concrete, metal façades and high-performance glazing. Five bars outside is often zero inside. A stronger outdoor signal does not fix that: you need an internal coverage system.
Repeater or DAS: what is the difference?
A repeater amplifies the existing outdoor signal and re-broadcasts it indoors. That works for smaller buildings where the outdoor signal is still stable. For large sites, underground zones or buildings with little external signal, a DAS (Distributed Antenna System) is the standard: a network of antennas spreads the signal across the whole building, for all operators at once.
Why a cheap booster from a web shop is not a solution
Consumer repeaters cover a few rooms at most, usually work for a single operator and are not simply permitted in Belgium. A badly tuned amplifier can disturb the outdoor network. Mercuron only uses compliant equipment and aligns every system with the operators’ requirements.
Why modern buildings are Faraday cages
Glazing with a metal coating stops radio signal as effectively as a concrete wall. Energy-efficient buildings become digital isolation cells: even with a mast 200 metres away, no usable signal gets in. A professional system brings the connection inside, with stable coverage on every floor.
How we check that it works
After installation we carry out a validation measurement throughout the building and deliver a measurement report. You see in black and white which zones are covered and at what signal level. That report is also the proof at handover and at later inspections.
Common situations and how we solve them
Underground car park with no signal
Concrete ceilings and walls block every outdoor signal. Anyone parking below misses calls until they are back upstairs. Antennas on every level, fed by one central unit, solve this down to the lowest basement.
Meeting rooms in the core of the building
Interior spaces without an outside wall often get no signal, and that is exactly where calls drop. Strategically placed antennas keep every point of the building reachable, the core included.
Production hall with metal walls
Steel façade panels and machinery block radio signal almost completely. Maintenance or emergency calls do not get through. A tailor-made DAS covers the entire hall, including warehouse areas and high zones.
Visitors on different operators
Customers, suppliers and staff do not all use the same provider. A multi-operator system supports Proximus, Orange and BASE/Telenet simultaneously, so nobody is left without a connection.
