How does the NBN technology Work?

In this digital age, it is important to embrace new technologies in broadband that enable us to better connect with other people and improve our day-to-day activities, whether they be work, entertainment or leisure.

In Australia, the National Broadband Network (NBN) is being rolled out. This is our new high-speed broadband network. It aims to replace or upgrade the existing telecommunication networks that provide phone and internet access. The upgrade to NBN is mandatory. However, the process is not automatic and it differs depending on your area. Don’t worry – you will be notified before your current service is disconnected to make way for the NBN upgrade. If you are not sure, you can contact your service provider.

How does the NBN Technology Work?

Fixed wireless

If you’re using fixed wireless, a rooftop antenna and a Network Termination Device will be set up in your property to access the NBN network. This is ideal for areas where the premises have quite a distance between them.


Fibre To The Node (FTTN) technology involves the installation of an NBN Node to deliver the final connection over the copper network through a vectored VDSL2 technology.


Fibre To The Premises uses an optic fibre line that runs through the nearest available node to your area. In this type of connection, an approved NBN installer or service provider installs an NBN network device.


With Hybrid Fibre Coaxial technology, fibre enters a distribution area and an NBN optical node is installed to deliver the final connection over cable TV through DOCSIS 3.0 technology. With this network, you need to buy your own DOCSIS cable modem.


With a Fibre To The Building (FTTB) connection, the fibre enters an apartment block or building, and using VDSL2 technology, equipment (DSLAM) is installed to deliver the final connection over the copper network. You can access this network by buying your own VDSL2 modem or use the one from your service provider.

NBN Installation and Equipment

An NBN technician may need to go to your premises to connect you to the network. Also, your existing networking equipment including modems and routers may be upgraded as you migrate over to the NBN.
