Boosting Mobile Signals
Nextivity solutions have you covered throughout the day - where you Work, Live, and Go
As the largest distributor of all CEL-FI products in Australia, Powertec Wireless Technology is helping Australians enjoy mobile phone signal in their vehicles, boats, offices, buildings and homes.
In today’s connected world, reliable mobile phone service and mobile data is essential to business, home and in vehicles where a single phone call can make or break a deal or put a worrying mind at ease, however mobile networks can only be built to cover so far. Many of us can find ourselves out west, behind hills, in the bush, or even a basement where a phone signal can’t reach.
CEL-FI GO's product line includes the first carrier-class cellular coverage solutions to offer industry-leading signal gain. Through Nextivity proprietary, award-winning Intelliboost® technology and signal processing, In addition to delivering the best voice and data performance in their class, GO systems are guaranteed to be unconditionally network safe and do not interfere with other wireless devices which is why they are the only Carrier Approved Mobile Signal Boosters in Australia.
Benefits of Nextivity CEL-FI Mobile Signal Boosters
Nextivity CEL-FI repeaters are 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.
Australia's vast and varied landscape includes numerous remote areas where cellular signal is weak or non-existent. The CEL-FI mobile signal repeater addresses this issue by significantly boosting signal strength. This is particularly beneficial for residents and businesses in rural or remote areas of Australia who often struggle with poor mobile reception.
Improved signal strength means reliable communication, essential for both personal and business purposes. It ensures that emergency calls can be made without disruption, a critical factor in remote locations. Additionally, for industries like mining and agriculture, which are prevalent in remote Australian areas, consistent and strong cellular signals are vital for operations and safety.
A lesser-known yet significant advantage of using a CEL-FI repeater is the extended battery life of mobile devices. When in areas of weak signal, mobile phones and tablets expend extra energy constantly searching for a better signal, which drains the battery quickly. By providing a stronger signal, the CEL-FI repeater reduces the need for this constant search, thereby conserving battery life.
For Australians who are often on the move or live in areas with poor reception, this means less frequent charging and longer periods of mobile phone usability. It is especially beneficial for those who rely on their mobile devices for long periods, such as travelers, remote workers, and emergency service personnel.
Slow internet speeds on your mobile device are often caused by low signal. If you suffer from low signal in your home you will be able to relate to the frustration of trying to access email or the internet.
The CEL-FI will amplify the mobile signal and increase your data speeds dramatically. Email, internet, video and social networking speeds will be like you never left the office.

Frequently Asked Questions
What makes CEL-FI so different from other mobile signal boosters?
CEL-FI mobile signal boosters are a smart signal boosters due to their industry-leading signal gain, intelligent boosting technology, and carrier-approved status. Unlike traditional boosters that amplify all signals indiscriminately, CEL-FI devices focus on enhancing the specific carrier signal required, providing up to 100dB gain for robust coverage even in challenging environments without compromising or interfering with your mobile operator’s networks or impeding other subscribers’ signals. This targeted approach ensures optimal performance without interfering with other networks, making CEL-FI a reliable, legal and efficient choice for improving mobile reception.
CEL-FI has been recognised for its superior design and effectiveness and is the only consumer booster authorised for use by ACMA, the Australian Communications and Media Authority, and in other countries such as New Zealand and the UK.CEL-FI are the only cellular repeaters to be approved by network operators Telstra, Optus and Vodafone.
Does a CEL-FI Mobile Signal Booster support voice and data or voice only?
Yes, CEL-FI smart signal boosters can support both voice and data simultaneously.
Can CEL-FI boost the signal of multiple cellular networks at once?
CEL-FI signal boosters are operator specific, and will only boost one Operator’s channels at a time. Being Operator specific is one of the main reasons that CEL-FIs are network safe and can provide 100 dB of signal gain, and why they are the only signal booster approved by a growing number of Operators.
