Fixed wireless operator BigAir has purchased rival Link Innovations, gaining clients in capital cities and some regional areas.
The acquisition, worth up to $2.75 million depending on Link's performance over the next two financial years, is expected to add $2.8 million in revenue across the 2012-2013 financial year.
It is also expected to contribute up to $800,000 in earnings before interest, tax, depreciation and amortisation for the financial year after integration.
"Earnings in subsequent years are expected to further improve following completion of network integration," the company said in a statement.
BigAir said the acquisition would provide an "expanded network footprint and service offerings".
Link's public clients include the media and journalism trade union, and Norwest Business Park in Sydney's north-west.
It is the second such acquisition for BigAir in the past month, after it snapped up Queensland wireless operator Allegro Networks for $10.5 million in late May.
The company has targeted mining, defence and student accommodation markets as key growth areas in coming years.
