The Seoul Metropolitan Government (SMG) is shifting its public Wi-Fi policy from a focus on expansion to quality, aiming to become a “seamless connectivity city” where everyone can enjoy fast, stable connectivity without interruption. While previous efforts focused on increasing the number of installations, the city will now prioritize user experience—specifically speed and stability—enhancing service quality for both residents and visitors. With the rapid spread of generative AI and increasing consumption of high-definition videos, mobile data usage is rising quickly. Smartphone data usage per person is expected to nearly double, while wireless data traffic in Korea continues to grow by over 20% annually. Public Wi-Fi usage in Seoul is following the same trend, with the number of users and data consumption increasing by 19.3% and 11.1%, respectively. This year, the city will invest KRW 2.4 billion to replace 2,020 outdated public Wi-Fi units installed at major streets, traditional markets, welfare facilities, district offices, and bus stops across Seoul. As part of this initiative, Seoul will introduce Wi-Fi 7, the next-generation wireless communication technology. Wi-Fi 7 significantly enhances network speed and stability by simultaneously using multiple frequency bands, enabling faster processing of large-volume data and stable service even in environments with many simultaneous users. In preparation for an era of 30 million international visitors, the city will expand data-free zones by deploying high-quality public Wi-Fi in major tourist destinations such as Myeong-dong, Seongsu, and Hangang Parks. Currently, Seoul operates a total of 35,318 public Wi-Fi units across buses, bus stops, parks, markets, and welfare facilities, covering a wide range of everyday settings. The service supports an average of 4.21 million users daily and generates approximately KRW 230.1 billion in annual telecommunications cost savings, demonstrating its tangible benefits for citizens. The city will also reorganize its public Wi-Fi operating system, integrating management
