AI, 6G, and the Resilient Future of Connectivity

One of the key takeaways from this year’s Mobile World Congress in MWC Barcelona was the growing influence of AI across both hardware and software. New AI-driven applications and innovations are emerging at an unprecedented pace, creating significant opportunities for the information and communication technology (ICT) sector. These advancements are rapidly integrating AI into our professional and personal lives, making it an indispensable part of future networks.

While the rollout of 5G is still ongoing, with substantial deployments yet to be completed, the industry is already setting its sights on 6G. The 3GPP has initiated early standardisation efforts, and the ITU-R has outlined key attributes that will shape the next generation of mobile networks. The vision for 6G includes AI-native architectures, ubiquitous connectivity, quantum-safe encryption, and a strong focus on sustainability. However, balancing these elements will be a complex challenge.

Supplementary technology

In February, CW launched its first 6G Introduction training course as part of CW Academy. The course was led by Zahid Ghadialy Ghadialy, Principal Analyst & Consultant at 3G4G , who shared an interesting perspective:

"6G will end up as a supplementary technology to 5G and will be a lot simpler than most people believe. It will use an enhanced version of the 5G core and will only be deployed in areas where a high density of users affects the experience. It will be designed as a good compromise, ensuring everyone benefits."

Despite the many promising applications of 5G, its adoption has not gained the momentum the industry expected when the hype first began a decade ago. Nevertheless, AI and 6G enthusiasts are already looking ahead to the next evolution. Initially, much of the discussion around 5G focused on millimetre-wave (mmWave) spectrum, but real-world challenges have prompted a shift away from terahertz (THz) and sub-THz frequencies. Instead, industry attention is now turning towards the so-called "upper mid-band" spectrum, ranging from 7-15 GHz, which may offer a more practical balance between coverage and capacity.

When the first set of 6G standards is finalised – after countless hours of research, debate, and development – it may be time for the industry to take a step back and reconsider whether the cycle of new ‘G’ generations remains the best way forward, or if a different approach is needed.
