What is 6G?
6G is the next generation of mobile communications, expected in the early 2030s. It builds directly on what 5G has already started. While early research talks about futuristic applications, the realistic picture is simpler: 6G will make wireless networks faster, more consistent, and available in more places, especially where today’s networks struggle. But is 6G what we really want?
What are the most noticeable changes?
The most noticeable changes will come from three practical advances:
1. Higher speeds and lower delays—mainly for demanding data use.
6G will push data rate beyond what 5G typically delivers, likely into the multi-gigabit per second range for everyday users. It will also reduce delays (latency) further, which matters for gaming, cloud computing, and interactive applications. This isn’t about sci-fi “instant” networks, but about making performance more steady and predictable, even in busy areas. This is being delivered by means of “edge networking”.
2. Much better coverage—thanks to satellite integration.
A major realistic feature of 6G is deep integration between terrestrial mobile networks and low-Earth-orbit satellites. Instead of satellites being separate systems, 6G aims to let phones and IoT devices stay connected almost anywhere—rural areas, roads, coastlines, and during travel. This will improve safety services, rural broadband, and basic connectivity far more than 5G currently can.
3. Smarter, more efficient networks—using practical AI.
AI will play a role, but not in a dramatic, “super-intelligent network” sense. Instead, AI will help mobile operators automatically optimise the network: adjusting capacity during busy hours, improving signal reliability, predicting and diagnosing faults, and reducing energy use. This will make the experience more consistent for users and help operators manage increasingly complex infrastructure.
What will it really mean for us?
1. Stronger security
Stronger security built in from the start, vital given the looming “quantum threat” and todays cyber security climate.
2. Faster Wireless Connectivity
For most people, 6G will feel less like a revolution and more like the point where wireless connectivity becomes fast, reliable, and available wherever we go, without the patchiness we still experience today. The benefits will be very real, even if less glamorous than some early vision documents suggest.
Is 6G what we really want?
But is 6G what we really want? Will it deliver? What are the blockers? Is 6G stimulated for technologists by technologist or are users at the heart?
