Frequently asked questions

Modern construction materials such as concrete, metal, and energy‑efficient glass block or weaken mobile signals, often turning basements, warehouses, or office interiors into ‘dead zones’. Our indoor coverage solutions overcome these obstacles by redistributing a strong, stable signal throughout the building.

Each solution is tailored to building size and needs. The Mobile Coverage Extender Pro 4G is ideal for small offices, while Proxicell systems (Small, Medium, Large) cover larger or multi‑floor sites using distributed antennas and repeaters for consistent 2G, 4G and 5G signal.

Start with an assessment (on-site if needed) by a Proximus expert. In case of an on-site assessment, they measure current signal strength, analyse building layout and materials, and recommend the most efficient and cost‑effective indoor coverage setup for your business.

The Mobile Coverage Extender Pro 4G connects via a Proximus internet box (fiber or VDSL). Small and Medium Proxicell don’t use any Proximus fixed connection, they capture the outdoor signal and reamplify the signal indoors. Large Proxicell use a point-to-point fiber connection to connect the on-site base station with the Proximus core network.

All current Proximus indoor coverage solutions support 4G, others 5G as well, some also include 2G for legacy devices or IoT applications. Configurations depend on your building's needs and device usage.

Capacity scales with the chosen solution. The Mobile Coverage Extender Pro 4G supports up to 32 users simultaneously, while Proxicell Large can serve hundreds of users in high‑traffic or multi‑tenant environments.

Yes. For multi‑operator or shared buildings, Proximus offers Distributed Antenna System (DAS) solutions, ensuring coverage for several mobile networks in one infrastructure.

After a site survey and design phase, installation typically takes between a few hours (for smaller devices) and several days (for complex DAS setups). All systems are deployed by certified Proximus technicians and include post‑installation performance testing.

Absolutely. For smaller offices or limited areas, VoWiFi allows employees to call and text over your Wi‑Fi network seamlessly, switching automatically between Wi‑Fi and mobile signal for uninterrupted connectivity.

Simply contact a Proximus advisor. Provide a floorplan and short description of your site, and our experts will arrange an assessment, plan your indoor coverage solution, and guide you from design to installation.
