No SIM Card Required
The existing operator signal is repeated over RF; the repeater itself does not require a SIM card or fixed internet connection for basic RF operation.

INDOOR MOBILE COVERAGE
Stella Doradus 4G 5G Repeater Solutions
The Stella Doradus 4G 5G repeater range is designed to improve indoor cellular coverage where reinforced concrete, metal structures, low-emissivity glass or other building losses weaken the outdoor mobile signal. Solutions range from homes and small offices to hotels, factories, large commercial buildings, marine applications and multi-storey RF distribution systems.
The correct repeater system should be selected according to the usable outdoor signal, operator frequency bands, building losses, RF distribution architecture and the indoor areas that require coverage.
Designed and Manufactured in Ireland
Stella Doradus professional repeater systems are engineered and manufactured in Ireland for commercial indoor mobile coverage projects.
RED and ETSI Compliance
European models are designed to meet applicable Radio Equipment Directive and ETSI requirements for professional cellular repeater equipment.
2G, 3G, 4G and 5G Support
Supported cellular technologies and frequency bands depend on the selected repeater model and the operator spectrum used at the project location.
Extended Warranty Options
Extended support packages are available for selected Stella Doradus repeater systems, depending on project and market requirements.
BağLAN Technical Support
BağLAN supports product selection, RF surveys, system planning, antenna distribution and project implementation for professional repeater installations.
Technical principle:
a repeater does not create a new mobile network signal. A usable operator signal with sufficient quality must be available
at the donor antenna location before it can be amplified and distributed indoors.

5G AND MULTI-BAND RF
Stella Doradus 5G Frequency Support
A Stella Doradus 4G 5G repeater can support multiple cellular frequency bands used for modern voice and data services, depending on the selected model. Multi-band repeater platforms allow the relevant licensed bands to be amplified and distributed through one coordinated indoor RF system.
700 MHz and 2100 MHz
5G services are deployed on different spectrum bands depending on the operator and country. Stella Doradus platforms support models covering B28 and B1 together with other cellular bands.
B28 · B1Carrier Aggregation
Carrier Aggregation allows compatible mobile devices to use multiple bands simultaneously. Multi-band repeater systems help preserve access to the frequency layers used by the operator.
Multi-band RFFuture Spectrum Requirements
New mobile spectrum allocations vary by market. Repeater selection should therefore be based on the exact frequency bands used by local operators rather than technology labels alone.

HOW IT WORKS
How Does a Mobile Signal Repeater Work?
A professional repeater transfers a usable outdoor mobile signal indoors through a controlled RF system consisting of a donor antenna, repeater, low-loss coaxial distribution and indoor service antennas.
1
Receive the Outdoor Signal
A donor antenna installed on the roof or another suitable exterior location receives the available mobile signal from the network.
2
Process and Amplify
The repeater filters and amplifies the selected cellular bands with controlled gain according to the available donor signal.
3
Distribute the RF Signal
The amplified signal is carried through low-loss RF cables, splitters and other passive components to the indoor antenna network.
4
Create Indoor Coverage
Ceiling or wall-mounted service antennas distribute the mobile signal into the target areas for phones, routers and cellular devices.
Critical RF design point:
sufficient isolation must be maintained between the donor and service antennas.
Repeater gain, outdoor signal conditions and indoor distribution losses should be engineered together.
SYSTEM SELECTION
Which Stella Doradus Repeater Solution Should You Choose?
Coverage area alone is not enough to select a Stella Doradus 4G 5G repeater. Supported bands, donor signal quality, the number of indoor antennas and the RF distribution architecture should all be considered.
| Application | Typical Solution | Typical Use | Details |
|---|---|---|---|
| Home / Villa / Small Office | R4-LCD | Small and medium indoor coverage | R4-LCD |
| Office / Hotel / Factory | Office Repeater / Titan | Multi-floor and multi-antenna RF distribution | Commercial building solutions |
| Large / Multi-Zone Building | Titan iRepeater | Scalable RF distribution with LineAmps and remote monitoring | Titan iRepeater |
| Boat / Yacht / Vessel | Stella Marine | Distribution of usable shore-based cellular signal onboard | Marine solutions |
RF survey recommended:
before the final system is selected, measure donor signal strength and quality, identify the operator bands in use
and estimate the RF distribution losses inside the building.
APPLICATIONS
Where Are 4G/5G Repeaters Used?
A Stella Doradus 4G 5G repeater is used where a usable outdoor cellular signal exists but building materials, underground areas or internal RF losses reduce mobile coverage inside the premises.
Offices and Business Centres
Improve mobile coverage in meeting rooms, internal corridors, core areas and multi-storey office environments.
Factories and Industrial Facilities
Support voice, mobile data and cellular IoT connectivity in buildings with heavy reinforced concrete and metal structures.
Hotels and Hospitality
Reduce indoor mobile dead zones in guest rooms, corridors, lobbies, service areas and other high-traffic spaces.
Warehouses and Logistics
Provide more consistent cellular coverage in large-volume buildings with metal shelving and enclosed operational areas.
Basements and Technical Areas
Extend coverage into underground floors, car parks, plant rooms and building cores where structural attenuation is high.
Shopping Centres and Large Commercial Areas
Use planned RF distribution to support indoor mobile coverage across large floor areas and high-user-density environments.
RF ENGINEERING AND REGULATION
Professional Repeater Design and Regulatory Compliance
A successful Stella Doradus 4G 5G repeater installation requires more than high gain. RF stability, network protection and local regulatory requirements must be considered together during design and commissioning.
Critical RF Design Requirements
- Maintain sufficient isolation between donor and indoor service antennas.
- Set repeater gain according to measured RF conditions.
- Check oscillation and feedback risk before final commissioning.
- Limit unnecessary uplink RF output and noise.
- Verify the operator bands actually used at the project location.
- Design the number and placement of indoor antennas according to the target coverage areas.
Local Spectrum and Installation Rules
Cellular repeaters operate on licensed mobile-operator spectrum. Installation and use may therefore be subject to local telecom-regulator rules, operator approval or installer requirements in the country where the system is deployed.
European RED/ETSI product compliance should not be treated as automatic installation authorisation in every market. Project-specific regulatory requirements should be checked before deployment.
SMART RF CONTROL
Stella Doradus Network Protection Features
Stella Doradus repeaters include automatic RF-control functions designed to support stable operation and reduce the risk of unwanted interaction with the mobile network.
Oscillation Detection
If insufficient antenna isolation creates feedback, the repeater can detect the condition and reduce gain to help maintain system stability.
Automatic Gain Control
The repeater monitors RF levels and automatically manages gain to help avoid excessive output while maintaining useful indoor coverage.
Reduced Output When Idle
When there is no active voice or data traffic, the system can reduce unnecessary RF output for more controlled uplink behaviour.
PROJECT TOOLS AND GUIDES
RF Survey, Design and Installation Resources
Professional projects benefit from a complete workflow: measure the RF environment, design the distribution system, commission the repeater and verify performance.
