Telecom is trialling new technology to turbo-charge broadband speeds, but it could be a while before users can take advantage of it.Very High Speed Digital Subscriber Line 2 (VDSL2) technology provides users with broadband speeds of up to 50Mbps. It is currently being trialled with ISPs that resell Telecom’s broadband services in Christchurch, Fendalton, Riccarton, Nelson, Wellington, Palmerston North and the Auckland suburbs of Devonport, Ellerslie and Howick, Browns Bay, Ponsonby, Glenfield and Remuera, as well as central Auckland.The catch with the new technology is that you have to live within 1km of an exchange in order to get the high speeds. In addition, Telecom wants to charge ISPs that want to offer VDSL2 a premium, which has prompted complaints to the Commerce Commission.
