South Korea continues to lead the development of 6G technologies.
In February 2023, South Korea’s Ministry of Science and ICT Technology unveiled the K-Network 2030 plan to strengthen the country’s position in 6G.
The plan includes developing cutting-edge technologies such as extreme Multiple-Input Multiple-Output in the upper mid-band, as well as building a cloud-based AI-powered root network and launching the first low-orbit satellite in 2027.
As part of the plan, the South Korean government allocated 441 billion won (about $325 million USD) for 6G research and development. Seoul aims to ensure the country’s leadership in standardisation and commercialisation of the technology.
The first phase of 6G standardisation is expected to begin in 2025, and the first commercial networks could be launched as early as 2028.
6G Leadership
In January 2025, the Electronics and Telecommunications Research Institute demonstrated a record-breaking 200 Gbps data transmission system in the sub-terahertz frequency range, marking a major step toward the development of 6G technologies.
6G is expected to be commercialised around 2030, opening up new opportunities for applications such as immersive metaverse experiences, hyper-connected Internet of Things, autonomous vehicles, and air mobility.
The Role of Artificial Intelligence in 6G
Artificial intelligence will be an integral part of 6G networks, playing a key role in data management, security, and improving connectivity.
AI will enable efficient processing of the vast amounts of data coming from billions of IoT devices, enabling intelligent traffic management and network resource optimisation.
AI systems will also be able to identify and prevent security threats in real time by analyzing behaviour patterns and anomalies in the network.
In the area of ​​connectivity, AI will adapt network parameters to ensure stable and fast connectivity, taking into account changing conditions and user needs. Thus, the integration of AI into 6G networks will create smarter, safer, and more efficient communications systems.
Challenges of 6G Rollout
However, the rollout of 6G networks in South Korea faces a number of challenges, including infrastructure development, regulations, data protection, and energy efficiency.
Infrastructure issues, such as the need to upgrade equipment and ensure broadband coverage, may slow down the rollout.
Regulatory barriers, including spectrum issues and international cooperation, require careful consideration. Data protection and cybersecurity are becoming a priority given the increasing volume of data transmitted.
South Korea’s commitment to 6G technology is set to revolutionise communications by driving innovation, efficiency, and leadership in global technology development.
