Trevor Manning has a long history of working in the microwave radio field. Following his graduation as an Electronics engineer with a specialisation in microwave, he spent some time in Italy working in the microwave radio research department of what is now Nokia. Working closely with the chairman of the ITU working group that wrote ITU-R P.530 – the main design document for radio link design – he gained both practical and theoretical insights into radio link design. These insights allowed him to design a very innovative microwave network in South Africa as part of a hundred-million-dollar network upgrade, which has stood the test of time. He went on to have national responsibility for the maintenance and operation of the network before moving to the UK to work for an American microwave manufacturer.
Trevor currently lives in Sydney where his focus is on leadership training of technical people but is still actively involved in innovative microwave design. He recently led a team of radio engineers to design and build the world’s longest high-capacity Ethernet link. Spanning over 200 km, this link achieves 99.9x% – before space and angle diversity improvements – despite being located in a tropical part of Australia. The real innovation is the fact that it has very small antennas installed low down on the tower, breaking all the conventional rules of radio link design.
