This video provides a visual guide to the installation process, covering unboxing, unit placement, and power connection for your Cel-Fi DUO+ Smart Signal Booster.
3.2. Pemasangan Langkah demi Langkah
The installation process is designed to be straightforward, requiring no external antennas or cables. The system is self-contained and self-configuring.
- Find the Best Cellular Signal: Use your mobile phone to identify the location in your home or office with the strongest existing 3G or 4G LTE signal. This is typically near a window, and often on an upper floor if applicable. Ensure your phone displays the 3G or 4G LTE icon. If no such signal is present, the booster cannot function.
- Place the Network Unit (NU): Position the Network Unit in the area where you found the best cellular signal. Plug it into a convenient power outlet. Ensure the unit is upright and its display faces towards the inside of the room. The NU will take a few minutes to complete its wake-up sequence and acquire the signal.
- Place the Coverage Unit (CU): Place the Coverage Unit in the area where you need improved cellular coverage. Plug it into a power outlet. The CU will establish communication with the NU.
- Optimize Setup with the Cel-Fi WAVE App: For final setup and activation, use the Cel-Fi WAVE app. This app helps you fine-tune the placement of your units for maximum coverage.

3.3. Optimizing Unit Placement
The distance between the Network Unit (NU) and the Coverage Unit (CU) is crucial for maximizing coverage. The further apart these units are, the larger the area of improved coverage will be. The total coverage area can be up to twice the distance between the NU and CU, with a maximum distance of up to 100 dB path loss.

4. Prinsip Operasi
The CEL-FI DUO+ operates by capturing an existing cellular signal from a nearby tower via the Network Unit (NU). This signal is then passed to the Coverage Unit (CU), which amplifies it and broadcasts it throughout your desired indoor area. For the system to function, there must be at least one bar of 3G or 4G LTE service available at the NU's placement location.
Figure 5: How the CEL-FI DUO+ Works
The Coverage Unit's numeric display indicates the size of the coverage area. Aim for a reading of 8 or 9 for optimal performance. A '0' indicates the units are too close, while a red icon (instead of green) suggests they are too far apart. Adjust placement accordingly to achieve the best signal amppemberitahuan.
5. Penyelenggaraan
To ensure optimal performance and longevity of your CEL-FI DUO+ system, consider the following maintenance tips:
- Keep both the Network Unit and Coverage Unit clean and free from dust. Use a soft, dry cloth for cleaning.
- Ensure proper ventilation around both units to prevent overheating. Do not block ventilation openings.
- Regularly check power connections to ensure they are secure.
- Avoid placing units in direct sunlight or in areas with extreme temperatures or humidity.
6. Penyelesaian masalah
If you encounter issues with your CEL-FI DUO+ Smart Signal Booster, refer to the following common troubleshooting steps:
- No Signal or Low Bars:
- Verify that there is an existing 3G or 4G LTE signal at the Network Unit's location using your mobile phone. The booster requires an existing signal to ampmerendahkan.
- Re-evaluate the placement of both the Network Unit and Coverage Unit. Try adjusting their distance to achieve an optimal reading (8 or 9) on the Coverage Unit's display.
- Check that both units are properly plugged into working power outlets.
- Coverage Unit Display Shows '0': This indicates the Network Unit and Coverage Unit are too close to each other. Move the Coverage Unit farther away from the Network Unit.
- Coverage Unit Display Shows Red Icon: This indicates the Network Unit and Coverage Unit are too far apart or there's an obstruction. Move the Coverage Unit closer to the Network Unit.
- Cel-Fi WAVE App Issues: If the app is not connecting or functioning correctly, try reinstalling the app or checking your device's Bluetooth connection.
- Intermittent Coverage: Ensure there are no large metal objects or thick walls directly between the Network Unit and Coverage Unit that could interfere with their communication.
