The 6G network will be the next big step in mobile technology, expected to launch around 2030. Currently in the research phase, it promises to go far beyond 5G and 4G with faster speeds, lower latency, greater capacity, and better connectivity. Using THz frequencies for higher bandwidth, AI for smarter networks, and quantum communication for advanced security, 6G will power exciting applications like holographic communication, brain-machine interfaces, autonomous systems, and the Internet of Everything (IoE), paving the way for a highly connected and intelligent future.
The foundational advancement of 6G indicates significant performance enhancements over previous generations:
- Spectrum Efficiency: With 5–10x improvement over 5G, 6G will maximise the spectrum use, enabling high-capacity transmissions for increasing network demands.
- Peak Data Rates: Exceeding 1 Tb/s, 6G will support next-generation applications like holographic communications and high-resolution immersive experiences.
- Latency: Reduced to 10–100 µs for over-the-air (OTA) transmissions, 6G enables ultra-reliable real-time applications such as brain-machine interfaces, autonomous systems, and tactile internet.
- Mobility: With support for 1000 km/h speed, 6G supports high-speed transportation systems like hypersonic travel and advanced railway systems.
- Connectivity Density: Connecting >10⁷ devices/km² will support dense IoT ecosystems, including smart cities, industrial automation, and ambient intelligence.
- Energy Efficiency: Efficiency to be improved 100 times, emphasising sustainability and minimising the environmental impact of the growing digital ecosystem.
- Traffic Capacity: With an area traffic capacity of up to 1 Gbps/m², 6G will provide consistent performance in densely populated urban centres and during high-traffic events.
