What is the Difference Between 3G and 4G in Australia?

The main differences between 3G and 4G networks in Australia are speed, capacity, and the types of applications they support. Here are the key differences:

• Frequencies: In Australia, 3G networks typically use the 850MHz, 900MHz, and 2,100MHz frequencies, while 4G adds 700MHz, 1,800MHz, 2,300MHz, and 2,600MHz to the mix. These additional spectrums contribute to 4G's higher speeds.
• Speeds: 4G download speeds can be twice as fast as 3G download speeds, and in some cases, even faster. 4G can reach speeds of up to 50Mbps, which is around 10 times faster than most 3G connections.
• Capacity: 4G networks can support more intensive mobile activities such as streaming and data transmission compared to 3G networks.
• Applications: 4G networks enable more responsive real-time applications and support streaming HD video, while 3G networks were designed primarily for voice communications rather than data.
• Device Capabilities: 4G also allows users to create mobile hotspots, sharing their high-speed internet connections with other devices, such as laptops or tablets.
• Coverage: 3G provides the backbone coverage in many less populous areas of Australia. However, as 4G networks expand, 3G networks are being phased out. For example, Telstra's 3G network is scheduled to be closed down in mid-2024.
• Future Developments: 5G networks are starting to expand across Australia, offering even faster speeds and improved capabilities compared to both 3G and 4G networks.

Comparative Table: 3G vs 4G in Australia

The difference between 3G and 4G networks in Australia can be summarized in the following table:

3G provides the backbone coverage in many less populous areas of Australia, while 4G offers faster download speeds and is mainly restricted to coastal areas and major inland regional areas. Telstra, the largest network operator in the country, has announced that it will ensure all of its 3G coverage areas will be upgraded to 4G before it shuts down the 3G network. The 3G network is set to begin shutting down from December 15, 2023, with Vodafone.
