Understanding the nbn™ speeds

Understanding the nbn™ speeds

The purpose of this article is to provide you with all the information you need to know about the speed capabilities of the different nbn™ technologies being rolled out by nbn™ Co across Australia, and the different factors which can influence the connection speed you experience on your nbn™ connection.

What determines a customer’s connection speed?
There are four key elements that determine the speed capability experienced by an nbn™ connection.

  1. The ACN speed tier and it’s corresponding nbn speed tier that you select as part of your broadband connection
  2. The nbn™ technology type used to connect to the users home or office
  3. The capacity that ACN and its suppliers provide to connect to the nbn™ network
  4. The setup of your home or office network and your internet use

# Availability of ACN speed tiers on a customer’s nbn™ service is subject to confirmation of the actual line speed^ of the service after activation. The actual line speeds for an nbn™ connection will vary due to many different factors including the availability of nbn™ wholesale access speeds on the customer’s nbn™ access technology, the hardware and software configuration of device(s) being used, the number of users in your home, the type and source of content you are attempting to access and the WiFi performance achievable in your home or office. Access speeds are not applicable where your service has been slowed/speed limited (‘shaped’) as a result of exceeding the data quota allocated as part of your plan.

1Typical evening speed is the typical download speed you can expect during peak busy periods (6:30pm to 11:30pm).
^ ACN does not offer the Max Speed tier (nbn™ 100) on nbn™ FTTN/FTTB or Fixed Wireless technologies.

 What happens if a service cannot achieve a ACN speed tier or typical evening speed?

ACN is not able to confirm the maximum line speed of your nbn™ connection with our service provider until your service is installed and activated on the nbn™ network. This means that while you may choose to order a higher speed tier than that included in your plan, ACN is not able to verify whether your individual nbn™ connection can reach the highest speed level or typical evening speed of your connection at the time of purchase.

If we determine that your connection is not capable of supporting the speed tier you have purchased, we will contact you with an offer to move your service to a lower, achievable speed tier and credit back the associated charges or, offer you an exit from your contract.

nbn™ technology types

The nbn™ network is made up of a number of different access technology types which may be used to connect your home or business. This is the first key element which determines the maximum possible line speed you can access at your home or business. Note that you can always check the nbn™ technology available at your address on the nbn™ website available at https://www.nbnco.com.au.
The table below provides a list of the current nbn™ technologies available, the nbn speed tiers that are available from ACN and the factors which may prevent a connection using that type of technology from achieving the maximum possible line speed.
Access line speeds are offered by nbn™ as wholesale speed tiers and can be viewed at www.nbnco.com.au/learn-about-the-nbn/speed.html. It is important to note that the speeds indicated by nbn™ are the maximum line speeds achievable for each speed tier and are not available on all nbn™ technology types. It should also be noted that nbn™ does not provide any guarantee of minimum line speed as part of its wholesale service.

nbn™ technologyDescriptionWhat speed tiers are available from ACN?What can prevent you from experiencing these speeds?
Fibre to the Premises

(FTTP)

 

 

Connects to the nbn™ network via a direct connection to your premises using fibre cabling.Basic (10 Mbps typical evening speed1)

Boost (20 Mbps typical evening speed1)

nbn™ 50 (40 Mbps typical evening speed1)

nbn™ 100 (80 Mbps typical evening speed1)

Refer to the “Factors which may impact specific technologies” section below.
Fibre to the Basement

(FTTB)^

 

 

Connects fibre from the telephone exchange to the network boundary point inside your building (known as the Main Distribution Frame). The existing copper infrastructure is then used from the MDF into your home or business 

nbn™ 12 (10 Mbps typical evening speed1)

nbn™ 25 (20 Mbps typical evening speed1)

nbn™ 50 (40 Mbps typical evening speed1)

There are a several additional factors that are unique to nbn™ FTTB (and FTTN) services that can have a significant effect on a customer’s connection speed.

One of the most common factors impacting nbn™ FTTN/FTTB connections is the impact of the “Coexistence period”. During this 18-month period defined by nbn™ Co where customers are transitioning to nbn™ services, FTTN/FTTB services are limited and as a result will generally provide slower download and upload speeds. This period is  required to ensure that existing DSL and legacy phone services on the copper network are able to co-exist with the newer nbn™ services. The overall length, quality and condition of the copper line from the node in the building to your premises can also have a significant effect on a customer’s connection speed.
These factors are both outside of ACN’s control and may occur irrespective of the service provider a customer chooses to supply the nbn™ connection. It is for these reasons that ACN does not currently offer nbn™ 100 speeds on either FTTB or FTTN connections.

Fibre to the Node

(FTTN)^

 

Connects fibre infrastructure from the telephone exchange to the node/street cabinet. The existing copper infrastructure is then used from the node/cabinet to your home or businessnbn™ 12 (10 Mbps typical evening speed1)

nbn™ 25 (20 Mbps typical evening speed1)

nbn™ 50 (40 Mbps typical evening speed1)

This period is required to ensure that existing DSL and legacy phone services on the copper network are able to co-exist with the newer nbn™ services. The overall length, quality and condition of the copper line from the node in the street to your premises and within your home or business can have a significant effect on a customer’s connection speed. In these situations, heavy rain or prolonged wet weather conditions can impact connection speeds. These factors are outside of ACN’s control and may occur irrespective of the service provider a customer chooses to supply the nbn™ connection. It is for these reasons that ACN does not currently offer nbn™ 100 speeds on either FTTB or FTTN connections.

Fixed Wireless

(FW)^

Connects fibre infrastructure from the telephone exchange directly to a wireless base station. An antenna is fixed to your home or business to receive the signalnbn™ 12 (10 Mbps typical evening speed1)

nbn™ 25 (40 Mbps typical evening speed1)

Factors which may impact specific technologies

As well as the factors above, there are also a number of factors which will impact the speed that a customer will experience from their nbn™ connection.

Equipment: Hardware and software configuration of device(s) being used to access the internet.

WiFi: Your modem/router’s Wi-Fi capability, the size of your house, internals wall, baby monitors, cordless phones, other Wi-Fi networks in close proximity, Bluetooth® devices just to name a few.

Internet Content: Internet content may be sourced from anywhere around the world.  Depending upon the location of the server delivering your content and the capacity is provides, may be running slowly due to a heightened demand.

Number of devices using your network: Your internet can slow when multiple device share the same connection.

Peak times: Internet speeds typically slow during busy peak times
