The Cel-fi Go is divided into two main categories: stationary and mobile. Depending on your specific requirements, we can help narrow down the best option for you.

The R41 ROAM model is tailored for mobile applications, making it ideal for caravans, cars, and boats. In contrast, the G41 and G51 models are intended for stationary settings. The R41 ROAM supports 3G, 4G and 5GNR Low Band.

If your focus is on stationary use, it’s essential to determine the size of the area you need to cover. The G41 is designed for smaller dwellings like a house, while the G51 is better suited for larger areas such as an apartment block or office building. The G41 supports 3G, 4G and 5GNR Low Band. The G51 supports 3G, 4G and 5GNR Mid Band.

But remember a base level of signal is required in your location for the Cel-fi GO to boost

Antenna dBi shows how focused its signal is. Low dBi means a shorter, wider range, while high dBi means a longer, narrower range. For car antennas, higher dBi is best for flat areas, and mid-range dBi (5-6 dBi) works better in hilly areas. The antenna height usually correlates with the dbi, for example the higher the dbi then the taller the antenna 

Think of it like a doughnut: with the same amount of dough (signal), you can make it tall and thin (long and narrow range) or flat and wide (short and broad range).

Good news! If you're unsure of where your local cell towers are, simply click on this link https://ausphonetowers.com.au/ enter your address, and the site will automatically retrieve the relevant information for you. With just this simple step, you’ll be one step closer to improving your reception.

5G operates on three types of frequency bands: low (below 1GHz), mid (1GHz–6GHz), and high (24GHz–40GHz). Each has its strengths:

- Low band: Offers wide coverage but slower speeds.
- Mid band: Balances coverage and speed.
- High band: Provides the fastest speeds but covers a smaller area.

5G can use multiple frequencies across these bands simultaneously for optimal performance, making it more flexible and reliable than previous networks.

A frequency band is a range of radio frequencies used to transmit signals over a network. These bands are part of the electromagnetic spectrum and are defined by their lower and upper frequency limits.

It’s possible that your area may not have 5G coverage, or the nearest 5G tower could be experiencing congestion due to high traffic. In such cases, the Cel-Fi GO unit intelligently adapts by switching to an alternative tower with less load, ensuring optimal performance.

The unit is designed to dynamically select the best available signal, whether from 4G or 3G networks, to provide consistent and reliable coverage even in areas where 5G connectivity is limited or unavailable.

By utilising this adaptive technology, the Cel-Fi GO ensures seamless signal enhancement across various conditions.

In order to initially register your device you will need to be in a location with sufficient reception. This is so that the app can successfully register your details and connect to the device. Please know this is only for registering.

if the device is constantly loading this could be due to being in a location with insufficient reception. Since the Cel-Fi GO is a signal booster rather than a standalone signal source, it requires a minimum base level of reception to function effectively.

If your device is not performing as expected, despite having this base level of signal, the issue is likely related to the firmware. In such cases, there's no need for concern. Simply contact our support team, and they will guide you through conducting a FieldWave test to diagnose and resolve the problem efficiently.

This diagnostic process ensures the booster is optimised to work correctly within your coverage environment.

The first step in diagnosing the issue is to observe when the signal interruption began. Consider whether you were travelling on familiar routes where the device previously worked or if this occurred in a new area.

Next, inspect the unit for any flashing lights, noting the pattern and frequency of the flashes, as this can provide valuable diagnostic information (please refer above to error codes and blinking).

The next step to try is a system reboot, please see below.

1. Unplug the power supply and plug it back in after 5-10 minutes

2. Uninstall and reinstall the Wave app on your phone

3. Make sure that your phone is not connected to any other Bluetooth devices (For example, smartwatch, car Bluetooth, headphones)

4. Resync the Wave app and see how it goes

5. If the same issue persists, then please use another phone and see if it works

 Additionally, ensure that all relevant applications and software have been updated to the latest versions.

If you have tried all of the above and you are still unable to see results, then please contact us via the support form. Please include the above information as this will assist our support team in conducting a more thorough investigation and effectively troubleshooting the issue.

The Cel-Fi system operates using two primary apps: one for monitoring and configuration, and the other for connecting your phone to the device.

1. Wave App: This app acts as the communication interface between the user and the Cel-Fi unit. It enables you to manage and monitor the device with various critical features, including:

- Operator Switching: Selects the network operator.

- Mode Switching: Adjusts the operating mode (e.g., 3G, 4G).

- Booster Settings: Configures signal boosting preferences.

- Registration: Registers the unit for network access.

- Antenna Position Test: Helps find the optimal antenna placement for maximum signal strength.

2. MyWave App: This app is responsible for connecting your phone as the primary device or "host." It ensures the Cel-Fi unit follows the settings configured for your phone. Unlike the Wave app, the MyWave app requires a constant connection to maintain communication with the Cel-Fi unit and ensure seamless device pairing. Please note this app must remain open at all times.

Both apps work in tandem, with the Wave App providing control and configuration, while the MyWave App ensures that the unit stays paired with your mobile device based on your selected settings.

Every mobile device has different algorithms for selecting signal bars. One thing that you can do to test this is to perform a field test on your mobile device. This field test will allow you to view the raw signal strength in your current location.

Below are updated instructions for the most popular mobile brands.

1. With the Cel-Fi plugged in, use your phone's Field Test Mode Code to check the signal strength and note the number.

2. Unplug the Cel-Fi and wait a few minutes for the signal strength to update. Compare the new number to the previous one.

Apple iOS 10.3.1 and newer

1.  Dial 3001#12345# 2. Select “LTE” 3. Select “Serving Cell Meas” signal strength will be displayed as “RSRP0”

Most Android Devices

1. Go to Apps 2.Settings 3.General 4.About Device Status 5. You will find Signal Strength on this screen

UMTS

1. Dial 3001#12345# 2. Select “UMTS” 3. Select “Serving Cell Meas” signal strength will be displayed as “RSCP0”

Samsung

1. Dial #0011# 2.The Signal Indicator will be displayed as RI or RSRP.

iOS versions OLDER than 10.3.1

1. Dial 3001#12345#* 2.Hold the Power/Lock button until you see “Slide to power off”. Do not power off, but release the power button. 3. Hold the Home button until the phone goes back to your home screen. At this time you should now see your raw signal strength instead of bars on the top left of your handset. 4. to go back to bars, dial 3001#12345# and tap the home button to Exit Field Test Mode.

Remember, a smaller negative number means a stronger signal. For example, if your signal goes from -111 to -100, it is 10 times stronger with the CEL-FI. Even a 3-point difference (e.g., -110 to -107) means the signal is twice as strong. Signal strength ranges from -120 (weak) to -60 (very strong). Even small improvements can make a big difference!
