Mobile repeaters (3G/4G/5G)
A mobile phone repeater is a type of “active repeater” antenna. It’s a telecommunications device that takes a mobile signal and re-broadcasts it through a specific area, and are particularly useful in rural, regional and remote areas of Australia.
This page provides information about repeaters that are legal to use for broadcasting the Telstra, Optus, and Vodafone networks.
What are mobile repeaters?
Repeaters receive a mobile signal at a location where it’s strong (which includes via cables to a passive antenna on your roof), and broadcasts (or repeats) the signal in a circle centred on the repeater itself.
The range of such systems can vary, but is between 20m and 60m, depending on the particular unit and possible interference from walls, furniture, and so on.
Repeaters such as these require licensing from the network that they’re broadcasting. They can only broadcast one network; for example, you can’t buy a Cel-fi that will broadcast both the Telstra and Optus networks.
Boosters that are not licensed are illegal. Using them can interfere with the mobile network, so their use can land the user with a large fine.
“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)
NB: Cel-Fi Pro and GO Repeaters and Telstra Branded Smart Antennas/Cel-Fi Go are the same devices, with the Telstra supplied one being different in colour, with Telstra branding.
The below repeaters & the Telstra branded repeaters are the ONLY licensed and legal repeaters that can be legally used in Australia.

It is highly recommended to use surge protectors with the Cel-Fi Pro and Go Stationary devices, and a UPS unit to power the repeater during general mains power failures or when the generator is off. They’re designed to power a desktop for 15 minutes or so, but are large enough to power a CelFi repeater for much longer.
The CEL-FI Go Mobile is a Smart Signal booster for addressing the challenge of poor cellular coverage on the road. Ideal for vehicles and boats, a suitable antenna is needed and these are recommended to be installed by a professional.

How do I know if an antenna will work for me?
A desktop site survey can assist you with determining if there is mobile reception in your area, and what equipment might be needed to get connected.
The above businesses can then put you in touch with a specialist in your area who understands the requirements for your state. The report will advise likely signal levels, the sort of mobile services available, the best antenna and extension device for your location and where to point your antenna.
