What Is 6G? Everything You Need to Know About the Next Generation of Mobile Networks

Don’t get left behind, learn everything about 6G before it releases! Mobile connectivity is evolving faster than ever. Just as 5G is rolling out in the UK, attention is turning to 6G, the sixth generation of mobile networks. Promising speeds that make 5G look slow, near-zero latency, and AI-powered intelligence, 6G is expected to revolutionise business operations, communications, and digital services by the early 2030s.

This article explains what 6G is, how it works, when it will arrive in the UK, and what businesses can expect. We also explore use cases, benefits, and the technologies that underpin this next-generation network.

What Is 6G?

6G is the successor to 5G and represents a significant technological leap. While 5G focused on faster downloads, lower latency, and better connectivity for mobile devices and IoT, 6G is expected to take these capabilities much further.

At its core, 6G is a hyper-connected, ultra-fast network that integrates artificial intelligence, advanced antenna systems, high-frequency terahertz bands, and intelligent edge computing. Early studies suggest peak speeds could reach 1 terabit per second, enabling instantaneous downloads of even the largest files. Latency could fall below 1 millisecond, supporting applications that require real-time responsiveness, such as remote surgery, driverless vehicles, and immersive virtual reality.

6G is also expected to integrate networked sensing, the ability to detect objects, positions, and environmental changes in real time without relying solely on external sensors. This opens up applications in smart cities, logistics, and industrial automation that were previously impossible.

When Will 6G Come to the UK?

The UK Wireless Infrastructure Strategy states that “standards-setting will begin by 2025”. According to industry forecasts, 6G trials in the UK are likely to begin around 2027 to 2029, with commercial services rolling out between 2030 and 2032. The UK’s participation in international research programmes ensures alignment with global standards, which is essential for interoperability with devices and networks worldwide.

Initially, trial networks will focus on major cities and industrial hubs, allowing operators to test coverage, latency, and reliability under real-world conditions. Wider rollout will follow once networks are validated and consumer devices become available.

When Will 6G Launch Globally?

The short answer: don’t hold your breath for the next couple of years. The global 6G launch depends on the 3GPP and ITU finishing the official standards, and they’re aiming to wrap that up by 2028. Once that’s done, phone makers and network vendors can finally start building proper 6G kit.

Countries in Asia usually jump on new mobile tech first, so expect the earliest real-world networks there. For the rest of us, most analysts reckon proper, widespread 6G coverage won’t kick in until the early 2030s. Just like 4G and 5G, it’ll roll out country by country, so some places will be on 6G while others are still catching up.

6G Speed vs 5G

Honestly, the numbers sound made-up: 6G could hit 1 terabit per second at its peak. That’s 50–100x faster than the best 5G you can get today (around 10–20 Gbps in perfect lab conditions) and literally thousands of times quicker than the 50–200 Mbps most of us live with.

In everyday terms? A 4K movie would download before you’ve even blinked, holographic calls would feel like the person is right there, and even the most demanding VR or AI apps would run smoothly from the cloud with no lag at all. 5G felt fast when it arrived; 6G is aiming to make “waiting for things to load” a thing of the past.

What Will 6G Do That 5G Cannot?

6G is designed to enable a set of capabilities beyond what 5G can provide:

• Extreme speeds: While 5G offers peak speeds of up to 10 gigabits per second, 6G could reach 1 terabit per second. Businesses could stream ultra-high-definition content, perform real-time cloud computing, and transmit massive datasets instantly.
• Ultra-low latency: Latency under 1 millisecond will enable truly real-time applications. Autonomous vehicles could coordinate safely, robotic systems could respond instantly, and immersive AR or VR applications would function without lag.
• Integrated AI: 6G networks will embed AI to optimise traffic, predict demand, and manage devices automatically. Networks will self-heal, allocate resources efficiently, and prioritise critical business traffic.
• Enhanced coverage: 6G will combine terrestrial and satellite networks to reduce dead zones. This ensures reliable connectivity in remote areas, improving logistics, field services, and mobile workforce operations.
• Advanced sensing: Networks will detect environmental and positional data. Applications include monitoring factory floors, tracking assets in real time, and improving safety and automation in complex environments.

How 6G Mobile Devices Will Change Work

6G mobile devices will be far more than phones. They will act as powerful computing hubs, capable of:

• Connecting to cloud AI for real-time analytics
• Performing complex computations without relying on external servers
• Handling ultra-high-definition AR and VR applications
• Supporting advanced IoT device ecosystems

Businesses will use these devices for applications ranging from instant remote collaboration to high-speed mobile data processing. The devices themselves will likely include AI accelerators, enhanced security chips, and multi-band connectivity for seamless integration with 6G networks.

Why Do We Need 6G?

The demand for connectivity is growing exponentially. By 2030, billions of devices, sensors, vehicles, and smart systems will require constant, low-latency connections. Existing 5G networks, while capable, will eventually struggle with the scale and complexity of future applications.

6G is being designed to handle:

• Massive IoT deployments: Cities, factories, and transportation networks will rely on billions of interconnected devices.
• Real-time remote operations: From remote healthcare to industrial automation, tasks that require instant feedback will depend on ultra-low latency.
• Data-heavy applications: Holographic meetings, AR-enhanced training, and fully immersive digital experiences will require terabit-level speeds.

Without 6G, businesses and public services could face bottlenecks, delayed decision-making, and reduced operational efficiency.

When Will 6G Replace 5G in the UK?

6G is currently expected to release in the UK from around 2035 and beyond, with the first commercial services appearing around 2030. Furthermore, 6G will not immediately replace 5G. Like previous network generations (read about the 3G switch off), 5G will also coexist with 6G for many years. Businesses will adopt 6G gradually as devices become available, coverage expands, and applications justify the upgrade. Organisations should plan for hybrid networks where 5G continues to provide reliable connectivity while 6G is phased in strategically.

Benefits of 6G for Businesses

6G will transform business operations by enabling:

• Real-time decision-making: Access to instant data insights will support faster, more accurate decisions.
• Remote and hybrid work enhancements: Teams can collaborate through ultra-high-definition video, holographic calls, and AR/VR tools without lag.
• Automation and smart systems: AI-driven networks will improve logistics, manufacturing, and customer service.
• Global connectivity: Remote sites, rural areas, and mobile teams will gain reliable access to critical business systems.
• New business models: Industries can offer services previously impossible, from autonomous delivery fleets to immersive digital experiences for clients.

How 6G Works

6G networks will rely on several key technologies:

• Terahertz (THz) spectrum: Frequencies above 100 GHz will deliver unprecedented speeds and bandwidth, though coverage challenges will require advanced antenna systems.
• Massive MIMO and beamforming: These technologies focus signals to devices rather than broadcasting widely, improving efficiency and coverage.
• AI and edge computing: Network intelligence will be distributed, allowing data to be processed near the device rather than in distant data centres.
• Integration with satellites: Hybrid satellite-terrestrial networks will ensure global coverage, even in remote or underserved areas.

Together, these technologies make 6G faster, smarter, and more reliable than any previous network.
