The Cel-Fi GO Booster Models


If you are wondering why the Cel-Fi GO comes in two flavours, a ‘Stationary’ & ‘Mobile’ version, then this is the article you need to read.

GO ‘Mobile’
GO ‘Stationary’




The ‘Mobile’ version of GO is designed for moving applications. It has the ability to switch towers at a faster speed and supports travelling at speeds greater than 60km/h.

It has a lower system gain to assist in protecting the network if in close range of a mobile phone tower.

The boosting threshold limits the GO to only boost when the signal is poor. This is to prevent a degraded level of service, especially in 4G mode.



The ‘Stationary’ version of GO is designed for fixed applications. It is not recommended for speeds greater than 60km/h.

As it is designed for fixed applications away from a mobile phone towers the system gain is not limited.



System Gain: 70dB



System Gain: 100dB



Supported Speed: 0-120km/h



Supported Speed: 0-60km/h



Tower Switching Speed: Fast



Tower Switching Speed: Slow



Boosting Threshold: only boosts when signal is worse than -80dB (3G) or -95dB (4G)



Boosting Threshold: no limitations


  • Hi, I’m looking at use of a stationary unit in a larger building. Is there any limit on the number of users that it can handle for voice calls and data ? We have over 100 persons in the building.

    • Hi Henry, Cel-Fi PRO was tested by the manufacturer Nextivity and they guarantee up to 25 people can utilise the device at the same time. They did not continue testing for higher numbers than this – it is possible the device can do them. The device has been used for offices with similar size staff and we have not received any negative feedback. I hope that helps you.

  • I have just got myself a CEL-FI Go and noticed there is a USB port on the side, is it possible to use the USB port to monitor the device as my PC doesn’t have bluetooth?

  • what is the expected maximum range from a cell tower with the mobile go unit?
    And expected fitted p[rice to motorhome?

    • HI Brett – The expected range of mobile signal can vary according to the terrain, vegetation, frequency band, volume of users, height of tower and type of tower. There are too many variables to give an exact range. In an ideal scenario like a boat out at sea with a tower high on the mountain, we have seen customers 180km from a tower able to make calls. It is better to talk in terms of being able to make calls where they usually break up, driving between towns with drops outs along the way in spots that now don’t drop out. Being able to SMS and get internet, where before you had signal but no data throughput. Usually having one bar of signal but you now have three…… these are the typical things we hear.

      With regards to the fitted price, you will need to speak to your local expert – the product cost including all the antennas can be found on this website:

  • Hi Cell-Fi, will you ever consider selling a unit with the external antenna, some of us boaties have already invested in top of line 3G, 4G and 4GX antennas and wish to re use them. Especially the other chap Allan that has his already on top of his yachts 13m mast, a huge job to replace. I cant see how another model antenna can effect warranty if its compatible with the 3g, 4g and 4gx bands…Mark

    • Cel-Fi GO comes with approved and tested antennas that we know perform well. Whilst the system may work with other antennas, we cannot endorse their use. GO not only relies on the antenna to pick up the signal, it also relies on the indoor and outdoor antennas not interfering with each other to perform at an optimum level. As we have not tested other brands of antennas we are unable to comment on their performance when being used with GO.

  • Hi.
    Are these available to purchase through Telstra like the othe model.

    • Hi John – we are not aware of Telstra planning to sell GO direct to customers. They may use them internally for network applications.

  • I am sailing around Australia in my 29′ yacht, currently in Darwin. I work a week while on anchor where I can get internet & then sail for 2 days. I have a 7.5dBi aerial on top of the 13m high mast. There is a 10.3 diam. super low loss coax cable (LCU400 from Telco Antennas) down the mast & terminating with a patch cable & TS9 connector to the Telstra 4GX ZTE modem in the cabin.
    1. is the fixed version suitable ?
    2. Will the TS9 connector work ?
    3. Can I use the current aerial & cable ?

    Regards, Allan Haddow

    • Hi Allan – thanks for your query. Answers to your questions as follows:

      1. is the fixed version suitable ? Yes….. Cel-Fi GO stationary
      2. Will the TS9 connector work ? You will require a SMA male connector to connect to Cel-Fi GO for input signal.
      3. Can I use the current aerial & cable ? We offer a full package with all tested antennas and cables… no need to use the current aerial and cable you have. We recommend you purchase the marine pack which includes all the antennas required and has been tested to work with the product. Using non approved cable and antennas may result in the unit not performing or under performing and will impact your warranty.

      Hope that helps.

  • Hi

    Just wondering if you are intending getting this approved by Optus. I want it for travelling / caravan use and all my advise is that Optus is the service to use in remote areas

    • Hi Heather – At this stage unfortunately there is no product approved by Optus. We hope this changes but it is not something that will happen in the next few months.

  • As the 2G network is now history, when will the Go be released? It seems to be unnecessarily delayed.

    • Hi David – Just released. You can find all the information about it on this website and the packages available on the website. If you need an install, let us know your postcode and you can purchase and install from a local.

  • Hi
    Any advice as to when the go units will be available for purchase ??

    • Hi Patrik – Hopefully you have seen the release information. If not, the product is available now. You can find all the information on the product on this website and the packages available on If you would like to purchase and install from a local, please just send us your password and we can advise the closest reseller to you.

  • Does Cel-Fi GO , a ‘Stationary’ & ‘Mobile’ both connect to a 12V DC ?
    Also do they work with all Communication Service providers, and sold as a kit at what price when approved ?

    • The stationary model comes with a mains power supply, the mobile model comes with a 12v cigarette lighter adapter.
      GO will only support Telstra at this time. It will be sold in kits with antennas, prices are due out in the next 2 weeks and are yet to be confirmed.

  • I’m looking to use the Go to boost mobile reception in my caravan, mainly for internet use with some voice thrown in. I intend mounting a whip aerial on top of the van’s TV antenna pole with the Go installed in a top cupboard. I gather I’d be looking at the Stationary Go for this?

  • I want to use it on a boat that does less than 60km/h and sometimes is 100km from the mainland. Is the fixed version with 100db gain better for me? I also want mobile phone and Internet but I see some literature says it only boosts one band – will I still get both so I can be on both my laptop and phone at the same time?

    • Hi Ian, yes the stationary GO model will be the unit we recommend for marine use. It will come with an external marine antenna and internal antenna. If you want to have voice and internet active then you just need to select the 3G setting. At the moment 4G supports internet, and limited voice (dependant on the plan, phone and area you are in). So we recommend having the GO in the 3G setting.
