What Is NBN?


Hey, I’m James from London and I was wondering, what exactly is NBN?

Here Is what NBN Is

Here Is what NBN Is


Great question! The National Broadband Network (NBN) is a major infrastructure project in Australia aimed at providing faster and more reliable internet service. The NBN is designed to replace the older ADSL system and has been rolling out progressively across the country.


The NBN utilises a multi-technology mix including copper wiring, cable broadband, and fibre optics to provide high-speed internet. Unlike the traditional ADSL system that relied solely on copper wiring, the NBN incorporates various technologies, such as fibre-optic lines, to improve speed and reduce bandwidth congestion.

Speed Tiers

You can select from four standard speed tiers offered by NBN providers:

  • Basic NBN 12/1
  • Standard NBN 25/5
  • Standard Plus NBN 50/20
  • Premium NBN 100/20

Each tier provides different upload and download speeds to cater to various internet needs. Some providers also offer ultra-fast plans that go beyond these standard tiers.

NBN Co: The Backbone of NBN

NBN Co is the company responsible for rolling out the NBN and acts as the wholesaler for internet service providers. Here’s how it works:

  • NBN Co manages the network.
  • NBN providers purchase services from NBN Co.
  • Customers select an NBN provider for their internet service.

Types of NBN Connections

There are seven main types of NBN connections:

  • Fibre to the Node (FTTN)
  • Fibre to the Curb (FTTC)
  • Fibre to the Building (FTTB)
  • Fibre to the Premises (FTTP)
  • Hybrid Fibre-Coaxial (HFC)
  • Fixed Wireless
  • Satellite

Each connection type has its pros and cons. For example, FTTP offers the fastest speeds but is less commonly available than FTTN or FTTC.

Broadband vs NBN

While the terms “broadband” and “NBN” are often used interchangeably, it’s important to note that NBN specifically refers to the network built and managed by NBN Co. Broadband is a more generic term that includes any high-speed internet connection.

Who Installs the NBN?

The initial installation is conducted by NBN Co. Once you choose your provider, they’ll guide you through the remaining setup, which could include connecting a modem to the NBN network. Some providers may charge a separate installation fee.

Why Choose NBN?

The NBN offers higher speeds and better reliability compared to older systems, making it a preferred choice for many Australians for work, education, and entertainment.

I hope this clears up any questions you have about the NBN. It’s quite a transformative project aimed at redefining Australia’s internet landscape.
