DOCSIS 3.1 coming to nbn at the end of the year

Company to retrospectively replace end user equipment to enable higher speeds using new cable broadband technology

The company responsible for building the National Broadband Network, nbn, has updated its Integrated Product Roadmap — revealing that it will be upgrading its HFC network termination device (NTD) to the DOCSIS 3.1 standard in the fourth quarter of 2016.

nbn is still yet to officially launch their HFC product, which is still scheduled to launch in June 2016. Last month, the company revealed at a Senate Committee hearing that they still have not signed construction contracts for the HFC rollout and the initial launch will be limited to a pilot area in Redcliffe, Queensland.

Initially, nbn will utilise DOCSIS 3.0 technology to deliver services to end users. Since HFC is a shared medium, traditionally, cable networks have heavy congestion and severely reduced speed during peak hours.

DOCSIS 3.1 promises to increase capacity through increased spectral efficiency, thus easing congestion.

In-flight satellite consultation in June

NBN will also be consulting with its service providers over “a mobility solution” which will include “a wide range of applications” including in-flight Wi-Fi connectivity, emergency services and health and education.

This consultation comes as Qantas announced it will team up with ViaSat to trial in-flight Wi-Fi services by utilising the NBN satellites on select domestic flights.

Detailed analysis of the proposal conducted by jxeeno blog found it would likely have minimal impact to existing satellite congestion due to the short periods of time a plane flies over a particular NBN spot beam.

Enterprise satellite consultation in third quarter

Separately, nbn will also be consulting on the delivery of enterprise services over its satellites. While the roadmap provides no further detail on this consultation — at the last Senate Committee hearing, company executives had alluded potential use of NBN satellites in the defense department or other enterprise applications.

NBN Mobile Backhaul and TV over fibre delayed

Initially slated for launch in the first quarter of 2016, nbn has delayed the launch of the NBN cell access service (mobile backhaul over the NBN) and its inclusion of TV signals over fibre in new developments till May this year.
