Cel-Fi Boosters

Active antennas or boosters (that are usually inside the house) boost the 3G / 4G signal.  Boosters such as these that require power to the unit (Telstra Smart Antennas & Nextivity Cel-Fi Repeaters) require licensing.  If they are not licensed they are ILLEGAL boosters.

Illegal boosters carry a large fine as they can interfere with the mobile network.

” It is an offence under the Radiocommunications Act 1992 (the Act) to operate an unlicensed radiocommunications device, or possess this device for the purpose of operation. A person found guilty of this offence may be imprisoned for two years for each offence. A body corporate may receive a penalty of up to $270,000 (1,500 penalty units) per offence (sections 46 and 47 of the Act). Other penalties may apply, such as the interference offence provisions at Part 4.2 of the Act.” ( ACMA )

Powertec Telecommunications are the only approved importer of the Nextivity Cel-Fi (outside of Telstra’s branded Smart Antenna).

RRP on the Telstra Cel-FI RS2 (3G) is $943.80 + Freight
RRP on the Telstra Cel-FI PRO (3G/4G) is $1,188.00 + Freight

Cel-Fi Boosters and Telstra branded Smart Antennas are similar. BIRRR highly recommend using surge protectors with these devices, you will need two surge protectors , one for each powerpoint.

UPDATE Jan 2017: Powertec have now released 2 new model boosters, the Cel-Fi GO Mobile and Cel-Fi GO Stationary. Cel-Fi GO Mobile is for moving vehicles and Cel-Fi GO Stationary for cabled building applications (ie small spaces like dongas, boats, farm equipment).

The Cel-Fi PRO models are still very relevant for office and home.

The GO is also IP rated so suits industrial applications and professional install is recommended.

More details can be found on the Powertec Website.

In Australia none of the carriers cooperate in the manner allowing a Cel-Fi to work across multiple carriers and only the Cel–Fi Pro and Telstra Smart Antenna are currently approved by Telstra for 4G, there are no other 4G repeaters currently approved. What this means is that each Carrier has their own specific model, at the moment only Telstra has a 4G model, if you want to cover multiple carriers, then you need to use multiple models.  A Telstra Smart Antenna OR a Nexitivity Cel-Fi will work on Telstra 4G network.

Tips on Simplified Cel-Fi Installation – Thanks to Marcus Dowling from Rising Connection

You may like to have two very long power extension leads to help with this while you move the CU & NU around find the best locations.
#1 before powering up the units, walk around your property and look for both the strongest and weakest signal on you mobile. This is important, with the Cel-Fi units, if the CU (Coverage Unit/Smaller box) picks up too much signal, it will automatically back its ability off, so find the areas where you get “BAD” signal (preferably none) as options as to where you will put the CU.

#2 (skip if not using an external antenna) choose two locations where you are not getting good signal, if the NU (Network Unit/Bigger box) can pick up enough signal with its internal antennas, it will by default ignore the external antenna, the NU has several very decent size antennas in it, way better than any normal mobile phone has.

#3 (skip if using an external antenna) put the NU (Network Unit/Bigger box) where you can find your strongest signal as in #1, that could be outside, just make sure the unit is protected from the weather and elements, the NU has several very decent size antennas in it, way better than any normal mobile phone has. Look to see that you are getting as many bars as possible (with the CU switched off) on the NU. The better you get the signal onto the NU, the better the CU will work in the next steps.

#4 Performance wise the NU & CU work best at around twenty (20) meters between them, this will vary depending on your building, some could be over 40 meters, some less then 15 meters, so place the CU now away from NU progressively looking at getting the number for the NU as high as possible, then take it that bit further where it fails (to far from the NU), it is good to know how far you can push the CU. Now the distance you took the CU to where it failed, use that as a guide to bringing the CU back into range, then bring the CU back some more, the CU will be more stable close than further away, when the CU is on the fringe, it can drop out causing your mobile connection to fail intermittently.

Just using these steps often achieves better performance than the performance specifications given for the Cel-Fi.

*Please note, while all care has been taken in compiling BIRRR documents, we recommend that you check with your service provider, local government and local installer regarding your own connection issues and infrastructure needed. Each state has different laws for antenna installation.
