The Nextivity CEL-FI GO G31 Smart Signal Repeater improves mobile voice and data connectivity in areas affected by weak cellular reception. Suitable for stationary and mobile installations, it receives available outdoor cellular signal through a donor antenna, amplifies it using Nextivity IntelliBoost technology and redistributes the improved signal through a service antenna. Carrier-specific configurations support Telstra, Optus and Vodafone, while the Nextivity WAVE App provides carrier switching, system configuration and monitoring. Intelligent signal processing, automatic gain control and echo cancellation help maintain stable operation without interfering with the mobile network.
Key Features
- Improved Mobile Coverage: Enhances cellular voice and data reception in areas affected by weak mobile signal.
- Telstra, Optus and Vodafone Support: Compatible with carrier-specific configurations for Australia's major mobile networks.
- Carrier Switching: Allows the configured carrier network to be changed through the Nextivity WAVE App.
- IntelliBoost Technology: Uses intelligent signal processing to amplify available cellular signal while maintaining network stability.
- Stationary and Mobile Applications: Supports installation in buildings, commercial facilities, vehicles, caravans and other compatible applications.
- Automatic Gain Control: Automatically manages amplification according to available signal conditions.
- Multi-User Coverage: Redistributes improved cellular signal for compatible devices operating on the selected carrier network.
- WAVE App Management: Supports configuration, monitoring and system management through a compatible mobile device.
- Network-Safe Operation: Automatically manages system performance to minimise interference with the carrier network.
- Cast Aluminium Housing: Uses a robust enclosure with passive cooling for fixed and mobile installations.
Enabling improved cellular reception where usable outdoor signal is available, the CEL-FI GO G31 supports flexible deployment across stationary and mobile environments. Its intelligent amplification and carrier-specific operation make it suitable for extending mobile connectivity into weak-signal areas.
Note: This is a refurbished unit that has been inspected and tested to ensure proper functionality.
