Challenges and Strategic Mitigation for the Korea 6G Network Plan

While the prospects of the Korea 6G network plan are immense, realizing its full potential involves navigating significant technical, regulatory, and economic hurdles.

As an industry expert, I recognize that overcoming these challenges requires not just innovation but also strategic foresight and agile adaptation.

One primary technical challenge is the limited propagation distance and high path loss of sub-THz waves, demanding a denser network infrastructure with numerous small cells and sophisticated relay systems.

Additionally, the power consumption of 6G devices and network components, operating at higher frequencies with more complex processing, needs to be meticulously managed to ensure sustainability.

The regulatory and standardization landscape is another complex arena, requiring active participation in global bodies like 3GPP and ITU to ensure international interoperability and avoid market fragmentation (OECD, 2026).

Korea’s strategy involves influencing these global standards from the outset, rather than reacting to them, a procedural detail that significantly impacts market advantage.

• **Spectrum Allocation Harmonization:** A critical procedural detail involves international consensus on harmonized global spectrum bands for 6G, which requires extensive diplomatic and technical negotiations. Without global harmonization, economies of scale for device manufacturing and international roaming will be severely hampered.
• **Cybersecurity and Privacy:** With hyper-connectivity and pervasive sensing, the attack surface expands exponentially, necessitating quantum-resistant encryption and robust identity management solutions from the ground up. KISA Korea is actively involved in developing secure communication protocols for this new era (KISA Korea, 2024).
• **Economic Viability:** The massive investment required for R&D and infrastructure deployment demands clear business models and compelling use cases to ensure a return on investment for operators and technology providers.

Mitigation strategies include focused R&D on energy-efficient hardware, advanced material science for improved signal propagation, and robust international collaboration frameworks.
