Understanding the 3G Network Shutdown

What is 3G?

The terms 3G and 4G have become increasingly familiar to us all. We know they relate to our mobiles and telecommunications, but what exactly do they mean?

Looking back twenty years, most of us can remember watching the little spinny circle on the computer screen after opening a website. How many people could put the kettle on, make a cuppa and put their feet up while that little circle kept spinning its heart out?

3G (third generation) gave us a new world of faster mobile data speeds and allowed technology like smartphones to evolve. It radically changed how we connect and communicate and has successfully guided us to 2024, an age of technology so advanced it can sometimes feel like we're living in a cut scene from Back to the Future.

Hutchison Telecommunications was the first to launch a 3G network in Australia under the brand "Three" in April 2003, using the 2100 MHz band. Telstra followed in October 2006 with its "Next G" network on the 850 MHz band, which gave better coverage, especially in the bush. Not long after, Optus and Vodafone jumped on the bandwagon with their 3G networks.

If 3G has been so good, why is it no longer needed?

Essentially, the answer is as simple as: it's no longer enough

Think of 4G and 5G like super-fast express trains, compared to the slower local trains of earlier technologies. These advanced networks are built to move more passengers (data) faster and without hitches, helping everyone get to places like high-definition video streaming and interactive online experiences—imagine swapping out sending telegrams or letters for instant emails!

Just as only so many trains can run on a track at once, radio frequencies that support our data are limited. By retiring the slower 3 also free up the 'tracks'—making room for the express trains to run more frequently and swiftly. This transition not only saves on costs but dramatically improves how quickly and efficiently we can communicate, much like the leap from manual, slower communications to instant digital connectivity.

Potential impacts for essential devices used by the elderly and people with disabilities

• Older mobile phones specifically designed for seniors that do not support 4G or 5G.
• Medical alert systems and personal emergency response devices that rely on 3G for connectivity.
• Some hearing aids and health monitoring devices that still use 3G technology.
• Home security systems and smart home devices that depend on 3G for communication.

Although the upgrade to 4G and 5G brings numerous benefits, it's important to recognise that the transition can have significant impacts on various types of devices, particularly those relied upon by the elderly or people with disabilities.

The 3G Shutdown Timeline

The Impact on Australians

We can expect a wave of new services and applications that need high-speed, high-efficiency data, like smart cities, telehealth, and advanced manufacturing.

While the 4G/5G transition brings better speeds and new capabilities, it poses challenges - especially for elderly or vulnerable users relying on older 3G-only devices to make calls and stay connected to emergency services or loved ones.

There are concerns that once 3G is shut off completely, those with non-compatible devices could become isolated and unable to access important communications, particularly in rural and remote areas that already have limited 4G and 5G coverage.

The costs of upgrading to new devices and learning how to use them could be a hassle, especially for those Aussies on tight budgets.

Telcos and the government are working to provide information and support to ensure a smooth device upgrade process. At KISA, we are proactively reaching out to customers ahead of time to let them know of the change and how it will impact them.

KISA is ready for 3G shutdown

KISA is committed to keeping people safe and connected. All of our devices are 4G and have been since 2018. If you have any questions about your current device or would like to find out more about devices KISA offers please contact us.
