Debate on best NBN options welcome THE boss of the national broadband network builder is open to a debate about alternative technologies for the future of Australia's telecommunications systems. The Labor government has directed NBN Co to build high-speed broadband optic-fibre cable to 93 per cent of homes, schools and business across Australia by June 2021, with the rest to be provided by fixed wireless and satellite services. Opposition communications spokesman Malcolm Turnbull advocates a greater mix of technologies, with more emphasis on the current fixed copper lines and pay-TV cables to improve broadband services in a shorter timeframe. NBN Co chief executive Mike Quigley, addressing the American Chamber of Commerce in Australia at a luncheon in Canberra on Friday, said the telecoms industry was well placed to provide more information. The Communications Alliance is considering a study into the potential pros and cons of a range of policy and technology options and the impact on the future of the NBN. "It is vitally important both the public debate and the policymakers have the advantage of the best information and analysis that can be made available," Mr Quigley said. They could bring commercial reality to the theoretical debate of what may or may not be technically possible. Mr Quigley urged retail and wholesale telco providers and consumer representatives to take part if the study went ahead.
