If you thought 5G was fast, brace yourself. 6G promises speeds exceeding 100 Gbps — enough to download 100 movies in one second. But speed is just the beginning: networks that “sense” the world, artificial intelligence embedded in every antenna, and holographic communications in real time. Welcome to 2035.

What Is 6G?
6G is the sixth generation of telecommunications technology, the successor to 5G. It is being developed under the International Telecommunication Union (ITU-R) within the IMT-2030 framework and is expected to become commercially available in the early 2030s. Companies like Nokia, Samsung, Ericsson, Huawei, and LG have announced active 6G research programs, while governments in the US, China, the EU, Japan, and South Korea are funding national initiatives.
From 1G to 6G: The Evolution
Every generation of telecommunications changes the world. 2G and 3G enabled voice and text. 4G brought mass data consumption and smartphones. 5G focused on the Internet of Things and industrial automation. 6G aims to merge physical spaces, digital data, and human interaction into one vast, sensor-laden web.
Nokia Bell Labs envisions "extrasensory experiences" where digital, physical and human worlds fuse. Intelligent systems will amplify human capabilities through raw computing power.

The 6 Pillars of 6G
🤖 Native AI/ML
Artificial intelligence won't be an add-on enhancement — it will be a foundational element. 6G radio systems will learn from each other, autonomously optimize transmission, and manage spectrum in real time.
📡 New Spectrum
Mid-bands 7-20 GHz for urban coverage, low bands 460-694 MHz for extreme coverage, and sub-THz frequencies for rates exceeding 100 Gbps. Samsung achieved 12 Gbit/s at 30 meters and LG 6 Gbit/s at 500 meters.
🔍 A Network That Senses
6G will detect objects, people, and environments by “listening” to bouncing signals. It will create real-time digital twins of the physical world — a network with a “sixth sense.”
⚡ Extreme Connectivity
Sub-millisecond latency, real-time holographic calls, in-vehicle networks with hundreds of sensors. Vehicles and robots will have wireless “nervous systems.”
🏗️ New Architectures
Distributed cloud, core and RAN convergence, networks of networks. AI-driven automation will dramatically reduce operational costs and increase reliability.
🔒 Security & Trust
Protection against cyber-attacks, jamming resistance, privacy in mixed reality worlds. As published in Nature Electronics, “security, secrecy and privacy should be key features.”

The First Experiments
Research isn't staying theoretical. In 2022, a Chinese laboratory (Purple Mountain Laboratories) achieved 206.25 Gbit/s in the terahertz band. Chinese researchers transmitted 1 terabyte of data over 1 kilometer using vortex waves. Japanese researchers at Nagoya University developed 3D superconducting niobium waveguides for communication at 100 GHz.
Geopolitical Race
The race for 6G already has a geopolitical dimension. China holds the largest number of 6G patents, South Korea plans commercial 6G by 2028, while 10 Western countries signed a joint statement for “open, secure and resilient” 6G in February 2024. Technological leadership in 6G could determine the geopolitical balance for decades to come.
How It Will Change Our Lives
The Timeline
Nokia expects commercial 6G systems by 2030, following the typical 10-year cycle between generations. The first standardization phase is expected in 3GPP Release 20 from 2026. Meanwhile, 5G-Advanced (Release 18) will fully leverage 5G capabilities, serving as a bridge to the new generation.
South Korea aims to launch 6G as early as 2028, while China launched the “first 6G test satellite” in November 2020. Europe is moving through Hexa-X, the 6G research flagship led by Nokia. Australia includes 6G in its telecommunications strategy, with Telstra committing $800 million.
