Business Profile

As one of Queensland’s largest energy retailers, this company supplies connectivity to over 2.3 million homes and more than 700,000 retail customers every year. Their vision is to ensure secure, affordable and sustainable energy solutions are provided for the community.

The Challenge

Connectivity is a major issue, with call dropouts occurring regularly, which is having a negative impact and management needs to rectify this. Austek; a certified Powertec installer was contacted to assess the mobile phone signal issue and design a reliable solution.


  • To increase cellular mobile signal for Telstra 3G and 4G reception within a concrete building

Products Used:


  • The Blackhawk Antenna will capture the signal from the nearby cellular tower. This signal will then connect to the repeater and be dispersed via the Pulse Larsen Antenna through the internal concrete structure.

The Solution

After a site visit by Jason from Austek, a CEL-FI GO solution was designed. Four Stationary CEL-FI GO units were installed inside the building, along with an external Blackhawk Wideband Mimo antenna and several internal ceiling antennas.
The external Mimo antenna was positioned to receive the strongest signal from a strategic Telstra tower, while the internal antennas we placed throughout the building to broadcast the boosted cellular signal.

This energy company are very happy with the results. The solution had provided the employees with a solid connection to the tower. This has reduced dropouts to zero and significantly improved data speeds.
With such a large customer base, the reliability of the mobile phone signal was imperative. Customers contact has been significantly improved and staff in the field are enjoying a more stable and reliable service.

Austek’s design and solution were efficiently deployed. This solution has broader applications across many industries and can be modified to suit yours.
