ATI History

ATI Australia Pty Ltd was created in 1991 as a private company focused on supporting enterprise WAN systems based on emerging microwave technology.

The company has grown organically and profitably over the intervening period to be recognised today as one of the largest suppliers of wireless technology in Australasia.

In 2021 ATI was acquired by Mayfield Group Holdings Ltd.

In 2022 ATI merged with Power Parameters Pty Ltd, the power quality solutions subsidiary of MGH. This merger brought over 100 years of power quality experience to the business and a strong strategic alignment given the critical power requirements of telecommunications networks.

Today ATI presents the Australasian market with a unique value proposition covering the engineering fields of wireless telecommunications as well as power quality monitoring and management with access to best of breed products and professional design and support teams.
