The rollout of NBN in rural Australia is a significant step towards bridging the digital divide between urban areas and the bush. Understanding how NBN connectivity works and the various technologies it uses can help you make informed decisions about your internet service.
As one of the leading NBN providers in South Australia, RBE Internet always strives to educate its customers. This article covers everything you need to know about NBN connectivity in regional Australia, from the different technology types to troubleshooting common issues.
What is NBN Connectivity?
The National Broadband Network (NBN) is Australia’s digital lifeline. This comprehensive broadband infrastructure is reshaping how Aussies consume the internet. As the rollout continues, 8.62 million homes and businesses are already connected to an NBN plan on its access network.
It aims to connect every Australian household and business with high speed internet. And that might soon be a reality, particularly with the consistent rollout of NBN in rural Australia. The NBN aims to replace the old copper phone lines with a modern and efficient system, primarily using fibre optic cables.
NBN Technologies
The NBN uses a multi-technology mix to improve regional internet access. Here are the main technologies it uses:
Fibre to the Premises (FTTP)
FTTP connects the NBN fibre optic network directly to your premises via overhead lines or underground utilities. This technology provides the most consistent and highest speeds, unaffected by distance. It requires an NTD (Network Termination Device) installed by NBN Co, which you connect to an NBN-compatible router.
Fibre to the Node (FTTN)
FTTN connects the NBN fibre optic network to a node located on the street. From there, it uses the existing copper telephone network to connect to your premises. Speeds are dependent on the distance from the node to your home. You will need an NBN-compatible VDSL modem or router connected to the telephone outlet.
Fibre to the Building (FTTB)
FTTB is similar to FTTN but with the node located inside the building’s communications room, typically used for multi-dwelling units and apartment blocks. The installation process is similar to FTTN, with the node inside the building instead of on the street.
Fibre to the Curb (FTTC)
FTTC connects the NBN fibre optic network to a Distribution Point Unit (DPU) located in a pit at the curb near your premises. From there, it uses the existing copper telephone network to connect to your home. This technology mitigates distance issues seen in FTTN. An NBN Connection Device (NCD) provided by NBN Co is required, which you connect to your copper telephone cable and then to an NBN-compatible router.
Hybrid Fibre-Coaxial (HFC)
HFC uses a mix of fibre optic and CATV (Cable TV) technology. It is largely built on existing HFC networks. The installation process is similar to other fibre technologies but utilises the existing coaxial cable infrastructure.
Fixed Wireless
Fixed Wireless plays a key role in delivering NBN in rural Australia, connecting regional areas to the NBN fibre optic network using fixed wireless radio towers. This technology can connect premises up to 14 km away from the tower. It requires an NTD and a Fixed Wireless antenna installed by NBN Co, which you connect to an NBN-compatible router.
Satellite (Sky Muster)
Satellite connections are essential for ensuring regional internet access, as they use telecommunications satellites to provide broadband services to remote areas where other technologies may not be viable. This technology is subject to data allowances and latency issues.
How NBN Connectivity Works
Network Infrastructure
The NBN network includes Points of Interconnection (POIs) where retailers connect their networks to the NBN. These POIs are typically located at telephone exchanges. Distribution fibre connects these POIs to neighbourhood hubs, cabinets, or nodes, which then distribute the signal to individual premises.
Connection Points
The technology used in your area determines the type of connection device installed at your premises. For example, FTTP requires an NTD, while FTTN uses existing copper infrastructure. These connection points are crucial for delivering the NBN signal to your home or business.
Domestic Network
Your service provider’s domestic network can affect the quality of your connection. Peak usage periods can lead to slower speeds if the provider’s capacity is not sufficient.
International Network
Your service provider connects to international networks, which can also impact your internet experience. How they manage their capacity here is critical.
Internet Congestion
Congestion can occur if many users access the same website simultaneously or if content owners’ server capacities are limited. This can affect your overall internet experience.
Key Components of NBN Connectivity
Points of Interconnection (POIs)
POIs are where retailers connect their networks to the NBN. These are crucial for ensuring data is transferred efficiently between the NBN and the retailer’s network.
Backhaul Networks
Backhaul networks are used by retailers to connect their own networks to the NBN POIs. Some retailers have their own backhaul networks, while others lease capacity from other providers.
Distribution Links
Distribution links vary in capacity depending on the area served. For example, FTTN cabinets typically serve around 200 end-users with 1-2 Gbps of capacity.
Retail Service Providers (RSPs)
RSPs are responsible for providing internet and phone services, installing and supporting connections, managing network capacity, and ensuring the quality of modems.
Choosing the Right NBN Plan
When selecting an NBN plan, it’s crucial to consider several factors:
Technology Type
Check which NBN technology is available in your area, as this will significantly impact regional internet access, speeds, and overall user experience.
Speed Tiers
Choose an NBN plan with a speed tier that suits your needs. Different technologies support different speed tiers, so it’s essential to understand what is available with your technology type.
Data Allowance
Ensure your NBN plan has a data allowance that meets your usage needs, especially if you are on a Fixed Wireless or Satellite connection.
Service Provider
Select an NBN plan from a service provider that offers good network capacity and support. The provider’s domestic network and international connectivity can significantly affect your internet experience.
Troubleshooting Common Issues
Slow Speeds
Check if the issue is with your service provider’s network capacity or if it’s related to the NBN technology type. Peak usage periods can also cause slower speeds, especially for NBN in rural Australia, where bandwidth limitations may be more noticeable. Ensure your modem and router are compatible and properly configured.
Outages
Check for any scheduled maintenance or outages in your area. Contact your service provider for assistance if the issue persists.
Connection Drops
Restart your modem and router to see if it resolves the issue. If not, contact your service provider for further assistance.
Conclusion
Understanding the different technologies and components of the NBN is crucial for making the most of your broadband connection. By knowing which technology type is available in your area and selecting the right NBN plan and service provider, you can ensure a reliable and fast internet experience.RBE Internet offers a range of tailored NBN plans designed to meet the needs of homes and businesses, especially in regional areas.
