HOW IT WORKS
Outdoor Donor Signal to Indoor Multi-Room Coverage
An outdoor donor antenna receives a usable mobile signal from the operator network. This signal is carried to the Stella Doradus Office Repeater, where it is amplified and distributed to indoor antennas installed in the required areas.
Correct donor-antenna placement, sufficient isolation between outdoor and indoor antennas, suitable RF cable routing and proper commissioning are essential for stable repeater operation.
NETWORK PROTECTION
Automatic RF Control for Stable Operation
The Stella Doradus Office Repeater includes control functions designed to reduce the risk of oscillation, excessive uplink power and unstable RF conditions.
Oscillation Detection
If donor and indoor antennas are installed with insufficient isolation, the repeater can detect feedback conditions and reduce gain to help maintain stable operation.
Automatic Gain Control
The repeater continuously adjusts operating gain to maintain appropriate signal levels and avoid unnecessary RF output toward the mobile network.
Uplink Activity Control
Uplink transmission is managed according to communication activity, helping reduce unnecessary RF noise when no active voice or data session is present.
Base-Station Level Detection
The repeater adapts its operating level according to the detected donor signal, increasing or reducing gain as required by the RF environment.
PORTSENSE
Stella Doradus PortSense Technology
PortSense is a Stella Doradus technology that helps automatically detect the connection status of the indoor and outdoor antennas connected to the Office Repeater. White LEDs on compatible Smart Antennas and repeater antenna ports allow the connection status to be checked quickly during installation.
When the cables, connectors and antennas are connected correctly, the corresponding LEDs illuminate. If an LED does not illuminate, the RF cable, connector or antenna connection may need to be checked. This makes it possible to identify connection problems more quickly during installation.
PortSense status can also be monitored through StellaControl. If the system detects a connection problem, it can be followed remotely through the monitoring and alert functions.
