Cel-Fi Wave App

Cel-Fi WAVE App


Cel-Fi WAVE offers a window into what is happening within the heart of a Cel-Fi smart booster. It also enables you to control certain features of the unit.

WAVE is currently available for the Cel-Fi GO or PRO. Android or Apple iOS devices are supported.

In this post we explore the latest version of WAVE with a Cel-Fi GO.

Start Screens
Ensure you are within a few metres of the GO unit and start the App. Once found, the App will start syncing data. If you have problems connecting try re-powering the GO and your phone.



The opening screen of the App is the dashboard that displays several things:

  • Errors – an explanation of any issues with the setup or hardware.
  • Signal Strength – from the network
  • Boost – represented by 1 to 9, with 9 being the most boost. Isolating the indoor antenna from the outdoor antenna will assist in increasing this number and therefore the coverage area. On the GO this figure is a direct coloration of the ‘Downlink System Gain’.
  • Operator – current operator being boosted
  • Coverage – if the unit is boosting 3G (3G/4G will be displayed), if boosting 4G (LTE will be displayed)



We like this tab as it offers the ability to control what frequencies Cel-Fi will boost. This is handy for optimising the unit for voice or internet, to maximise the internet speed or select a band that is compatible with all phones in a vehicle or room.

The settings tab displays the following:

  • Booster Name – you can assign a name to your Cel-Fi. Handy when you have multiple systems.
  • Software Version – let’s you know if you have the latest version
  • Booster Settings – control which technology is boosted (3G/4G/Auto) or which frequency (Band 3= 1800/Band 5 = 850/Band 28 = 700)




For those that consider themselves to be a tech boffin, the advanced screen is for you! It helps with setting up and optimising Cel-Fi due to the fact an exact signal strength measurement can be obtained.

Useful information that can be accessed include:

  • Donor RSSI – extact measurement of incoming mobile signal
  • Downlink Center Frequency – what frequency band is being boosted
  • External Antenna in Use – if the internal or external antenna is being utilised
  • ID – ability to see nearby towers and their signal strength
  • Downlink System Gain – the output power and coverage bubble size




To assist with solving complex technical support issues a send log function is available. This will send a copy of the working log to Nextivity technical support. You can change the email address to [email protected] for local support.




Help Centre
The WAVE App features a help section to assist with common problems that you may come across.



In summing-up, the WAVE App  is a very valuable tool in setting up Cel-Fi and optimising.

It is a must have when using a GO, as it enables you to control the 3G/4G/Auto button on the front of the GO when it is mounted under a car seat.

Now you are an expert you can GO and download the Android or iPhone App!

Our next article explains the differences between the two GO models and which one to use.

  • I have a iPhone 5s will this work with the cel fi

  • How to change the operator from Telsrta to Optus??????

    • Hi Manu, According to Australian law, each product is locked to a specific carrier. You will be unable to use the WAVE App to change the operator. You would need to access another version of the product compatible with your new carrier.

  • I like the look of your Pro Telstra model.

    With 4GX getting more popular, does this cover 4GX also? or only 4G?

    Also, I like the data pulled with the WAVE app, but do not want to use the App. Can I use a API to read the same information, I dont need to write/change with the API, just read status?


  • Hi. Very interested in your product as I was just looking at standard antenna and cradles etc. for boosting my phone and dongal reception in our caravan.
    Would I be correct in saying that your Go unit works similar to a modem? IE. We would not need to have our phones or dongal directly wired to anything. Therefore as long as we were in the caravan or sitting just outside we’d be able to use our phones?

    • Hi Phill, you are correct, you won’t need any device directly wired into anything. As long as you are within the GO coverage area you will be able to utilise the signal. If you compare GO with an antenna/cradle set-up, you will find that the gain (up to 100dB) is exponentially more powerful so will perform better in marginal areas. We have plenty of availability and prices can be found here: http://www.powertec.com.au/mobile-products/signal-repeaters/telstra-repeaters.

  • With the wave app is there is reason why it won’t connect if there is no network coverage?

    I’m using an iPhone 7 and if try to connect to the GO when there is no cell tower signal it will show the device found and then syncing data, then a wave portal error will come up and won’t connect no matter what I try.

    But soon as it’s in range of a cell tower it will connect fine every time??

    • Hi Andy, the WAVE App requires an internet connection to start up. It need to check the software version with the cloud server first. Unfortunately their is no way around this at the moment.

      • Why does the WAVE app need to check the software version with the cloud server on every start-up? This “feature” prevents the ability to access the settings menu if no internet connection is found thus rendering the device unusable.

        • Hi Jeff – Thanks for your enquiry. We have brought this up with the manufacturer and it is a necessary step in the boot up process to check for updates and operator configs. The app will also be used for online registration (coming in the next few months), so will need internet access to perform this function.

  • Hi is there any way to only make the unit boost 1800Mhz 4G as it seams to want lock onto the 700Mhz and the equipment I am using cant see 700Mhz 4Gx it can only see 1800Mhz

    • Yes with the Cel-Fi GO you can select the exact band you want to use in the WAVE App under settings. (see image in article above).

      With the Cel-Fi PRO, it does not have this option, it will just select the strongest 4G band. There is however a little trick you can do (if you are NOT using an external antenna), by setting 4G 1800 to ‘external antenna’ in the WAVE app. This will drop the signal on 1800 by 20dB and hopefully 700 will be stronger.

  • Looking at getting one or more of these for my RFS brigade as whilst we are mainly based in sydney, when our trucks get sent away for major fires both in nsw and interstate we normally end up in some really isolated areas, even sections of the blue mountains and areas up in the wollemi and yengo national parks have non existent service. though i have a question regarding how the auto function works, as for the most part 3g850 will do both the data and voice components, obviously we’d love to take advantage of the 4g capabilities for our mapping downloads etc. will the cel fi automatically switch between 3g for voice and 4g for data depending on what the demand is, ie if we’ve just downloaded a topographic map and then need to make a phone call will the cel fi automatically go from boosting 4g to boosting 3g, or will we have to manually change it via the wave app?

    • Hello Hans – Cel-Fi GO automatically defaults to 3G. You can manually switch to 4G via the app or on the device itself by pushing a button. You would have to switch it back to 3G for calls again. Hope that answers your questions. Let us know if you need any further information.
