NBN wireless: everything you need to know about fixed wireless connections

It’s easy to figure out when you’ll get hooked up to the NBN by popping your address into NBN Co’s website, but that doesn’t tell you what technology will keep you connected to the internet: fibre or fixed wireless.

According to NBN Co, about 5% of Aussies will be eligible for the fixed wireless connection – that’s around 600,000 premises, mostly in rural and remote parts of the country, where the distance between properties is too large to make laying fibre cost effective. 

For a fixed wireless connection, data is transmitted from a tower located a few kilometres away to a rooftop antenna installed at the customer’s premises.

What is fixed wireless technology

A fixed wireless NBN connection utilises a series of ground stations to relay 4G radio signals (similar to how mobile broadband or LTE technology works) to deliver broadband services to a home that could be located as far as 14km away.

This type of technology requires line of sight between the antenna and the tower, hence proving inefficient in the big smoke. It’s also restricted by distance – explaining the maximum of a 14km radius – and trees and metal rooftops could degrade the signal.

NBN Co is also restricting the number of premises that will be serviced by each tower, ensuring the bandwidth per household is higher and more consistent than a regular mobile broadband connection.

Equipment required for fixed wireless technology

As mentioned above, fixed wireless technology will require a rooftop antenna at the premises to receive radio signals from the ground station. 

If new construction work has been carried out at a property after the installation, NBN Co recommends a system check to be carried out in case the direction or height of the antenna needs to be changed to ensure line of sight for the best speeds possible.

Given that the antenna will need to be connected to the NBN Connection Box (provided by NBN Co) inside the home, a small hole will need to be drilled into a wall to allow a cable to pass through. Of course, the Connection Box will also need to be fixed to a wall close to a power socket. 

Like the installation of the backup battery for fibre connections, NBN Co offers the antenna as part of its service at no extra cost. That said, you may incur a setup fee when signing up for a plan with a service provider.

You will also need a modem router that can support the speed tier you opt for, but chances are your preferred telco will provide you with one that is NBN-ready.

Broadband speeds on fixed wireless

Historically, the maximum speed achieved on a fixed wireless connection was 25Mbps, but as of 2015, that was increased to a top download speed of 50Mbps and a maximum upload speed of 20Mbps.

Starting in early 2018, NBN will offer the 100Mbps/40Mbps speed tier to fixed wireless customers as well. Customers who would like to upgrade to the superfast speed tier may require new equipment to be installed that would be capable of supporting the increase in bandwidth.

It is important to note that customers may not achieve the maximum speeds advertised, but will depend on the outdoor equipment’s distance from the ground station and the line of sight. Internally, the placement of a cordless phone could also dampen speeds on a Wi-Fi network.

Cost of NBN fixed wireless connections

There isn’t much difference in terms of cost between a fibre connection and a fixed wireless one. They are mostly on par. 

The cost will depend on how much data you want per month and the speed tier you choose. Plans currently start at $ 29.90 for a limited data plan of 10GB per month, and can cost up to $ 100 per month on an unlimited data plan on the 50Mbps speed tier.
