Recent DOCSIS 3.1 trials on NBN's Hybrid Fibre Coaxial network (what used to be Telstra's pay TV cable) saw speeds of 1Gbps, according to NBN.
Held in a Melbourne lab, the trial also saw upstream speeds of 100 Mbps, which NBN says is more than double the current highest 40 Mbps upload retail speed available on HFC retail services over the NBN.
More lab testing of DOCSIS 3.1 is planned for August, with in-field scheduled for December. A commercial launch of DOCSIS 3.1 is expected in 2018.
"These early tests of DOCSIS 3.1 technology are very exciting," Bill Morrow, CEO at NBN, said. "DOCSIS 3.1 is going to be able to provide fantastic gigabit potential for end users – just as our Fibre-to-the-Premises (FTTP) network does today."
"The best news is that we will be able to bring Gigabit broadband to these premises far more quickly, cost effectively and with less disruption to end users than alternate technologies in these busy urban areas."
It was part of a competition to give one town the fastest internet in the country - and Wollongong was crowned the winner.
Up to 979 Mbps on the downlink and up to 129 Mbps on the uplink — that's what speedtest.net confirms has been achieved in a User Datagram Protocol test (used for realtime applications, like voice and video over the internet) of Telstra's live LTE network.
