Selected Operator
The repeater is tuned for the target operator and the cellular bands required by that operator at the installation site.

OPERATOR-SPECIFIC COMMERCIAL REPEATER
Stella Doradus OS6 Repeater
Commercial-grade single-operator repeater for large-building indoor mobile coverage
B28 | B20 | B8 | B3 | B1 | B7
The Stella Doradus OS6 is an operator-specific commercial cellular repeater designed to improve indoor mobile coverage for one selected mobile operator in large buildings. It supports voice and mobile-data services across the configured cellular bands, including 5G, 4G, 3G and 2G services where those services are deployed on the amplified frequencies.
OS6 combines multi-band amplification with PortSense, remote monitoring, automatic network scanning and advanced uplink-noise control. The system is intended for professional installations where operator-specific RF performance and protection of neighbouring operator networks are important design requirements.
SYSTEM OVERVIEW
OS6 and OS4 Models
The OS6 supports six cellular bands. The OS4 uses the same six-band platform but is configured for any four selected bands according to the target operator and project requirements.
- Operator-specific commercial-grade repeater architecture
- B28 / B20 / B8 / B3 / B1 / B7 support on OS6
- OS4 configurable for any four of the six supported bands
- PortSense antenna and cable connection checking
- Remote monitoring through StellaControl
- Automatic Cell Scan for donor-side RF visibility
- Carrier Aggregation support across amplified bands
- Advanced uplink-noise suppression for operator-specific deployments
| Model | Bands | PortSense | Monitoring | Cell Scan |
|---|---|---|---|---|
| OS6 | B28 / B20 / B8 / B3 / B1 / B7 | Yes | Yes | Yes |
| OS4 | Choose any 4 of the 6 bands | Yes | Yes | Yes |
OPERATOR-SPECIFIC RF CONTROL
Carrier-Grade Uplink Noise Suppression
Uplink-noise control is especially important in an operator-specific repeater because the installation must amplify the selected operator while avoiding unnecessary RF noise in spectrum used by other operators.
Neighbouring Operators
Uplink-noise suppression helps minimise unwanted RF energy in bands that are not assigned to the target operator.
Automatic Level Control
The repeater adapts its RF behaviour according to the operating environment and donor-side network conditions.
Professional Commissioning
Operator-specific systems should be commissioned from actual site measurements, antenna isolation and verified band requirements.
Design principle: Operator-specific repeaters should not be selected only from nominal band lists.
The target operator's real spectrum usage, donor-signal levels and the surrounding RF environment should be verified
by measurement before final configuration.
CARRIER AGGREGATION
Six-Band Architecture for Modern Mobile Networks
Amplifying multiple cellular bands is important for Carrier Aggregation. Compatible mobile devices and operator networks can use several frequency bands simultaneously, increasing the available bandwidth and supporting higher data rates and more robust indoor connectivity.
OS6 can amplify all six supported cellular bands within the operator-specific configuration, helping preserve the frequency layers used by the selected operator for voice, LTE and 5G services.
- B28 — 700 MHz
- B20 — 800 MHz
- B8 — 900 MHz
- B3 — 1800 MHz
- B1 — 2100 MHz
- B7 — 2600 MHz
NETWORK SCAN
Automatic Cell Scan for the Exterior RF Environment
The internal modem and embedded SIM allow the OS6 to perform an automatic Cell Scan. This provides periodic visibility of nearby cellular cells and donor-side RF conditions around the building.
Network-scan results can be reviewed through the monitoring environment to help confirm that incoming signal conditions remain suitable and to identify changes in the surrounding operator network.
PORTSENSE
Antenna and Cable Connection Monitoring
PortSense automatically detects antenna connections on the repeater ports. Compatible Smart Antennas and repeater port LEDs provide immediate visual confirmation when the RF hardware is connected correctly.
PortSense status is also monitored through StellaControl. Hardware faults, disconnections or system degradation can therefore be identified remotely and included in the installation's alert and maintenance workflow.
INSTALLATION WORKFLOW
Professional OS6 Repeater Project Process
A reliable operator-specific repeater installation should be based on building plans, RF measurements, detailed design and controlled commissioning rather than device selection alone.
1
Initial Review
Review building plans, coverage targets, operator requirements and the expected RF-distribution architecture.
2
On-Site RF Survey
Measure donor-side signal conditions and operator spectrum using suitable professional RF survey tools such as SHARK.
3
Design Proposal
Finalise antenna locations, cable routes, passive components, repeater configuration and the project BOM.
4
Installation and Monitoring
Commission the system, verify RF isolation and connect the repeater to StellaControl for ongoing supervision.
