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 support@powertec.com.au 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!
