NBN

« Back to Glossary Index

In today’s fast-paced digital economy, a stable, high-speed internet connection is the digital backbone of any successful business. In Australia, the National Broadband Network (nbn™ network) serves as the cornerstone of that connectivity. Developed and maintained by NBN Co, this Australian Government initiative is designed to modernize internet access across the country using a range of broadband technologies such as Fibre to the Node (FTTN), Fibre to the Premises (FTTP), Hybrid Fibre Coaxial (HFC), nbn Fixed Wireless, and nbn Satellite. Whether your business is streaming movies for a client presentation, conducting online shopping portals, or relying on VoIP carriage, a fast and reliable internet service provider is crucial. This guide provides a detailed overview of the nbn network, helping business owners better understand how to connect and optimize their internet service.

What Is the NBN?

The National Broadband Network, or nbn network, is a wholesale-only, open-access data network established by the Commonwealth of Australia. Operated by NBN Co, a Government Business Enterprise accountable to the Minister for Communications and Minister for Finance (Shareholder Ministers), the nbn network replaces outdated copper wire and coaxial cables with high-speed fibre optic cabling and other modern technologies. The Department of Communications and the Arts oversees the rollout and ensures alignment with the PGPA Act, Corporations Act, and the Statement of Expectations.

This project aims to deliver fast broadband services across the nation by connecting millions of premises passed using a range of internet connection types, such as:

• Fibre to the Premises (FTTP)
• Fibre to the Node (FTTN)
• Fibre to the Curb (FTTC)
• Hybrid Fibre Coaxial (HFC)
• Fibre to the Building (FTTB)
• nbn Fixed Wireless
• nbn Satellite (Sky Muster and Sky Muster Plus)

Why Was the NBN Introduced?

The Australian Government initiated the nbn rollout to combat the following challenges:

• Legacy Copper Lines: The existing Telstra telephone exchanges and copper cable infrastructure were unable to support high-speed internet.
• Network Capacity Constraints: Businesses faced slow download/upload speeds, latency times, and frequent outages.
• Market Failure: Inadequate private sector investment in fast broadband services prompted government intervention.
• Digital Equity: A need to bridge the digital divide between metropolitan, rural, and remote areas through technologies like Sky Muster satellite and nbn Fixed Wireless.
• Support for Critical Sectors: Health care, education networks, and mobile telecommunication backhaul all demanded a robust digital infrastructure.

How Does the NBN Work?

The nbn network is a wholesale platform where NBN Co provides infrastructure to internet service providers (ISPs), also called Retail Service Providers (RSPs). Here’s how the system functions:

1. Infrastructure Build: Fibre optic cables, fixed wireless towers, and geosynchronous satellites are deployed across the country.
2. Points of Interconnect (POIs): ISPs connect to NBN Co at POIs, enabling access to the national infrastructure.
3. Retail Delivery: ISPs sign up end users and deliver service via nbn connections boxes, Wi-Fi router/modem setups, and virtual circuits.

Delivery Methods

• FTTP: Direct fibre optic cabling to the premises for maximum speed.
• FTTN & FTTC: Optical fibre reaches a node or curb, with copper cable or coaxial cables carrying the final leg.
• HFC: Uses existing coaxial cables upgraded with fibre backhaul.
• Fixed Wireless & Satellite: Transmits signals wirelessly or from Sky Muster satellites for hard-to-reach regions.

 

Types of NBN Connections Explained

Different business premises receive different connection types, each with unique features and performance:

Connection Type	Description	Speed Tier Range	Availability	Best Use Case
FTTP	High-speed fibre to the premises	Up to Gigabit	Urban & business areas	Streaming, VoIP, multi-user businesses
FTTB	Fibre to the building (common in MDUs)	Moderate to High	Apartment blocks	Shared commercial premises
FTTN	Fibre to node with copper wire to premises	Variable	Nationwide	General residential, small business
FTTC	Fibre to the curb, short copper run	High	Urban areas	SMEs, higher speed than FTTN
HFC	Coaxial cables with fibre backhaul	High	Select locations	Small offices, digital TVs
Fixed Wireless	Tower to premises wireless connection	Moderate	Rural areas	Remote offices, farms
Satellite (Sky Muster)	Satellite-to-premises (remote-only)	Moderate	Remote/Outback	Backup, remote properties

NBN Rollout and Availability

The nbn rollout was strategically divided into phases. As of now, the majority of Australian premises passed have access to some form of nbn connection.

To check availability:

• Visit the official NBN Co site or consult your ISP.
• Enter your business address to find your internet connection type and speed tier availability.
• If unavailable, ask your service provider about Starlink satellites or interim mobile network options.

Benefits of the NBN for Businesses

• Speed Tiers to Match Needs: nbn plans come in various tiers (25/5, 50/20, 100/40, and even Gigabit), letting businesses choose their preferred speed tier percentage.
• Reliable Connectivity: Designed to support VoIP, digital TVs, internet banking, remote collaboration, and large data transfers.
• Geographical Reach: Even remote areas benefit from Sky Muster satellite and Fixed Wireless options.
• Modern Infrastructure: Fibre optic cables and Gigabit Passive Optical Networks ensure consistent high-speed access.
• Operational Efficiency: Supports fire alarm systems, monitored security alarms, EFTPOS, and cloud-based operations.

Challenges and Criticisms

• Political Influence: The rollout has seen multiple changes in direction and funding from the Commonwealth Government.
• Installation Delays: Business tenants in commercial spaces often experience delays due to coordination with building Owners’ Corporations.
• Service Variability: Speeds vary greatly depending on internet connection type and peak usage times.
• Upgrade Costs: Upgrading from FTTN to FTTP often incurs additional charges, though grants and co-funding may be available.

How to Transition Your Business to the NBN

1. Audit Equipment: Ensure landline phone systems, Wi-Fi router/modem, and Commander Business Modem are nbn-compatible.
2. Choose a Provider: Compare internet service providers and their nbn plans tailored for businesses.
3. Sign Up: Complete the sign up process, selecting an appropriate speed tier and contract length.
4. Installation: Coordinate with NBN Co or your ISP for technician visits and ensure minimal disruption.
5. Testing: Post-installation, verify latency times, connection strength, and backup systems.

Transition Tips

• Discuss fire alarm systems and monitored security alarms with your ISP to ensure compatibility.
• Backup data before the switch.
• Prepare your team for a short service interruption.

FAQs

1. What does it mean to be NBN-ready?
Your premises are equipped for connection via the nbn network, with necessary infrastructure installed.

2. Can I retain my current landline number?
Yes, most phone companies can port your number over during the sign up process.

3. Will existing copper lines still work?
In most cases, copper lines are decommissioned once FTTP or FTTN becomes active. Some legacy services may cease.

4. What if the NBN isn’t available in my area?
You can explore alternative providers or newer options like Starlink satellites.

5. How do I request an upgrade to fibre?
Apply through NBN Co’s Technology Choice Program or request upgrade details from your ISP.

Conclusion

The nbn™ network represents a monumental shift in how Australian businesses connect to the digital world. Whether you’re in the heart of Sydney or a remote town relying on Sky Muster, transitioning to the right internet connection type can dramatically improve efficiency, service delivery, and growth potential.
