Indoor Mobile Coverage for Shopping Malls and Supermarkets
Bring 4G and 5G services into areas where outdoor mobile signal is weakened by the building structure
Shopping malls and supermarkets can have excellent mobile signal outdoors while suffering from weak or unusable indoor mobile coverage. Reinforced concrete, steel structures, coated or double-glazed windows and large floor areas can significantly reduce the signal that reaches customers, staff and connected mobile devices.
Stella Doradus repeater systems are designed to receive usable operator signal from outside the building and distribute it through a professionally designed indoor antenna system. System size, antenna count and RF distribution are selected according to the building layout and measured signal conditions.

THE PROBLEM
Why Indoor Coverage Can Fail
- Outdoor mobile signal may be strong while signal levels drop sharply inside the building.
- Double glazing, reinforced concrete, steel walls and modern building materials can create substantial RF attenuation.
- Weak mobile data near checkout areas can affect app use, customer communication and mobile-dependent workflows.
- Large retail floors require planned service-antenna distribution rather than a single-point coverage approach.
THE OBJECTIVE
Reliable Coverage Where It Is Needed
- Distribute usable outdoor operator signal throughout the required indoor areas.
- Support customers and staff with voice and mobile-data access across the retail floor.
- Improve connectivity around checkout areas and locations where mobile applications are used.
- Design a scalable, operator-independent RF distribution system based on measured site conditions.
THE SOLUTION
Stella Doradus Repeater System
An indoor mobile coverage system can combine a Stella Doradus main repeater with LineAmp units, RF splitters, low-loss cable and multiple indoor service antennas. The exact architecture depends on the measured donor signal, supported bands, floor plan and target coverage zones.
- Multi-band cellular signal distribution
- No fixed internet connection required for the RF repeater function
- Operator-network protection and automatic RF control functions
- Scalable distribution for large indoor areas
- Remote monitoring and management on supported systems
- Professional design using donor and service antenna planning
REAL-WORLD APPLICATIONS
Shopping Mall and Supermarket Case Studies
Two documented Stella Doradus indoor mobile coverage installations illustrate how different retail layouts can require different RF distribution designs.
Large E. Leclerc Retail Installation
A Stella Doradus iRepeater system was deployed in a retail site in Soustons, France, where outdoor signal was good but indoor voice and mobile-data service had been severely reduced by the building.

NETWORK PROTECTION
Automatic RF Control Functions
Stella Doradus repeater systems include RF-control functions intended to help maintain stable operation and protect the mobile network.
Oscillation Detection
If donor and service antennas are insufficiently isolated, the repeater can detect feedback conditions and reduce gain automatically.
Automatic Gain Control
Automatic control continuously adjusts RF operating levels to help keep the system within its intended operating range.
Uplink Idle Mode
The uplink path can remain quiet when no call or data transmission is active, helping reduce unnecessary uplink noise.
Base-Station Level Control
The system adapts its operating level according to received network conditions instead of running continuously at unnecessary power.
