What is the NBN?
The NBN is not a single network but a policy and framework to introduce super-fast broadband to Australia.
However our government policy makers have defined anything above 25Mbps as super-fast which with today’s technology is not super-fast.
The Government has established its own company, which is funded by tax payers, NBN Co Limited, to roll out super-fast network infrastructure to existing (or what is called brownfield) dwellings and communities.
For new developments the developer can choose to use NBN Co to deliver the telecommunications infrastructure and services or they can choose a private super-fast network operator, all part of the NBN strategy.
These private operators do it faster, cheaper and without spending tax payers money. These networks are run just like NBN Co as a wholesale network service to which all ISPs, like Valve Networks can access to deliver our end to end retail services.
Due to oversight by the Australian government, NBN Co changed from a network which was supposed to be fibre all the way to your home or premises (known as FTTH or FTTP), to a mixed technology using copper in the last few hundred meters to deliver VDSL up to 100Mbps (FTTNode) and an advanced VDSL for FTTCurb. They also acquired the HFC or Hybrid Coax Fibre networks from Telstra and Optus to use this to deliver services.
Unfortunately, our regional towns and rural and remote communities (sometimes not so remote) NBN Co has chosen to use fixed-wireless and satellite technologies. The fixed-wireless has proven to be under provisioned and the technology is limited and so generally it will offer services not much better than a 25/5Mbps. Satellite ensures that we have coverage all over Australia, however the throughput, speed and amount of data downloads are limited.
