The Evolution of 5G: Looking Ahead to 6G and Energy Efficiency

As 5G networks continue to roll out and evolve, the mobile industry is already turning its gaze to the future. While some may feel that 5G has not lived up to its initial hype, it’s important to remember that the technology is still in its early stages of implementation. The first set of 5G standards was established in 2017, and since then, network rollouts have been ongoing.

One of the main criticisms of 5G has been the discrepancy between its promised capabilities and the actual user experience. However, it’s crucial to consider that as networks transition to 5G Standalone, performance and reliability will improve. Gartner analyst Bill Menezes believes that as carriers update their networks, users will begin to witness the promised improvements in speed and reliability.

Despite the current limitations, 5G is already delivering higher speeds, with estimates ranging from 75 Mbps to 240 Mbps in the UK. This is a significant improvement compared to 4G speeds and lays the foundation for future advancements.

Looking ahead, 5G-Advanced, marked by the release of 3GPP Release 18, is expected to address the limitations of the initial 5G rollouts. This next phase of 5G will introduce support for non-terrestrial networks, such as satellite connections, to increase coverage in remote areas. It will also enhance mobile broadband performance, support new applications like extended reality, and boost intelligent network automation.

While 5G-Advanced shows promise, it is important to acknowledge that it is just a stepping stone towards the eventual arrival of 6G networks. Nokia’s Peter Vetter stresses the need for 6G networks due to the projected exponential increase in mobile traffic. To accommodate this surge in traffic sustainably, the goal is to halve the total energy consumption of mobile networks with 6G. This will require significant improvements in energy efficiency and foundational research.

For 6G to succeed, it will need to offer higher speeds, more pervasive networks, and greater support for demanding applications. Nokia advocates for the use of spectrum just above the current mid-band range for 5G, as it allows for deployment from existing cell sites. Additionally, large-scale antenna arrays and innovative technologies like hybrid beamforming will be crucial for directing electromagnetic energy efficiently.

As the mobile industry moves closer to 6G, it becomes evident that the need for continued innovation and network standards is vital. Energy efficiency and sustainability will play a pivotal role in shaping the networks of the future. With careful research and development, 6G has the potential to revolutionize mobile connectivity and support the ever-increasing demands of our digital world.
