A technical solution to fix spurious emissions that sometimes come from the National Broadband Network or NBN fixed wireless network has been found. Steen Jensen VK7AP has raised the issue of severe interference to high frequencies, medium wave broadcasts and fire alerts in rural areas of Tasmania. Chris Holliday VK7JU in Deep Bay Tasmania also reports the same problems, and it may occur elsewhere with a particular brand of fixed wireless network device. Steen VK7AP thanked the WIA for its representations including statements to the ACMA backed up by Standard Australia compliance, and VK7WI broadcast publicity by Justin Giles-Clark VK7TW. The wireless network on 2300 MHz is acknowledged as being not supposed to result in interference.
Following inquiries and WIA representations, a manufacturer has proposed elimination of the problem caused by an Ethernet controller, through better isolation and the use of higher specification cabling.
A close watch is being kept on developments by the WIA and the ACMA, as the NBN continues to roll out its wireless network access fast broadband service.
