Cel-Fi is the only consumer mobile phone repeater that has been widely approved by all mobile carriers in Australia. Currently approved for use on the Telstra, Optus and Vodafone mobile networks, Cel-Fi is a new type of mobile enhancement device called a Smart Repeater. There are other non-compliant consumer repeaters that appear to be from Australia, buying non Cel-Fi repeaters may result in large fines and loss of the equipment.

What is a Smart Repeater?

A Smart Repeater is a new type of mobile phone repeater that is designed to complement an existing mobile network and not interfere with its operation. It does this by monitoring the base station levels in real time, only repeating the signal of one particular carrier and having inbuilt protection to ensure it does not overload or interfere with network operation. Cel-Fi is currently the only Smart Repeater in existence.
