What is 5G internet? 

5G represents the fifth generation of mobile networking, succeeding 1G, 2G, 3G, and 4G. Designed to connect objects, individuals, and devices, 5G promises significant innovations and benefits over its predecessors.

Evolution of Internet Speeds

• 1G: 2.4 kbps
• 2G: 64 kbps
• 3G: 144 kbps
• 4G: 100 Mbps to 1 Gbps
• 5G: Expected to deliver 20 Gbps peak data rates and 100+ Mbps average data rates

5G vs. 4G and Fibre-Optic Internet

5G is expected to deliver peak data rates of 20 Gbps and average rates exceeding 100 Mbps. This is a significant leap from the current fastest fibre-optic speeds of 1 Gbps. 

While 4G LTE networks offer speeds around 12.5 MB/s, 5G could reach speeds as high as 2.5 GB/s. This means a 3GB file that takes 30 minutes to download on 4G could take only 35 seconds on 5G. 

Global Implementation and Investment

Ericsson predicts that by 2024, 5G will cover 40% of the world and handle 25% of all mobile traffic. This rollout requires substantial investment, with over $4.2 billion projected to be spent on 5G infrastructure.

Wireless but Not Entirely

5G replaces the physical last-mile connection with a wireless one, though the core network will still rely on fibre-optic cables. The challenge lies in ensuring individual connections maintain high performance despite potential congestion and physical barriers.

Cost-Effective Installation

Compared to fibre-optic internet, 5G installation is cheaper and less labour-intensive. The plug-and-play nature of 5G means faster, easier deployment, making it a more attractive option for many.

Concerns and Myths

There have been many concerns raised about the safety of the 5G internet. The radio waves emitted by 5G devices and towers are similar to those emitted by previous generations of mobile technology and are well below international safety standards.

Will 5G Replace Fiber Optic Internet?

Despite the impressive advancements of 5G technology, it will not replace fibre optic internet. Instead, 5G will serve as a crucial complement, especially for last-mile connectivity, while fibre optics will continue to play an integral role in the core network infrastructure. 

ISPs will need to navigate a future where both technologies play a crucial role. Broadband market is expected to grow at a steady rate and ISPs will continue to play a dominant role in deploying last mile fibre for fixed broadband services. ISPs will need to manage operations to be efficient and scale as their networks grow.
