Proven expertise.

Since 1999, we have been working with Australian telecommunications carriers as part of their design team.

Our main focus is microwave link design and line-of-sight surveys. We have also installed and commissioned countless microwave links, built towers and installed mobile phone base stations.

Microwave link design

Through 4 decades of our directors' experience, we have designed thousands of microwave links both in Australia and overseas.

Line-of-sight surveys

Our experience and methodology in this field is unique and unrivalled. We have delivered over 10,000 line of sight reports in Australia to Optus, NBN, Transgrid, NSW Telco Authority, Vodafone, Telstra and other operators.

Line-of-sight survey (LoS) is the first and most important step in microwave link implementation. We use surveying techniques, special cameras and custom designed software tools to deliver accurate and reliable LoS reports with photographic evidence.

We are currently trialling drone surveys for LoS.
