Interview
In the run up to the World Communication Awards 2025, we spoke with shortlisted finalist KT to discuss their 5G journey and some of the most exciting use cases leveraging the new technology
KT is recognised as a global leader in 5G technology. What are KT’s major achievements since launching the world’s first commercial 5G service?
KT successfully launched the world’s first commercial 5G NSA network in 2019, leading the global telecommunications industry with groundbreaking innovation. This milestone went beyond technical advancement, fundamentally reshaping customer experiences and driving innovation across various industries. In 2021, KT further solidified its leadership by rolling out the nationwide Standalone (SA) 5G network, establishing approximately over 220 thousands base stations to provide high-quality 5G services across urban and rural areas
Through its efforts, KT extended network infrastructure to underserved rural regions, reducing the digital divide and ensuring accessibility for all. A notable strategy involved implementing network-sharing models in collaboration with other operators, accelerating the deployment of cost-effective base stations in remote areas.
Beyond connectivity, KT leveraged its 5G infrastructure to introduce tailored solutions for industries like manufacturing, logistics, healthcare, and education. For instance, its cloud-based private 5G network for smart factories has revolutionized operations by enabling real-time data analysis and automation, significantly boosting productivity.
From the customer’s perspective, how does KT’s 5G technology deliver a differentiated experience?
KT has continuously enhanced its customer-centric services by adopting innovative technologies and improving network quality. For instance, the deployment of 5G Small Cell technology ensures stable indoor signals, offering speeds of up to 1.4Gbps. This technology is particularly effective in large-scale venues such as malls, office buildings, and airports, dramatically improving network quality in traditionally weak signal areas
Additionally, KT’s Reconfigurable Intelligent Surface (RIS) technology uses small antennas installed on walls or windows to reflect and refract signals, ensuring high-quality connectivity in shadowed indoor areas. This solution is especially effective in complex environments where consistent connectivity is critical.
Moreover, KT’s AI-based customer quality analysis system processes over 1 billion data points daily, enabling real-time detection and resolution of potential network issues. For instance, in complex environments like subway tunnels, this system identifies and addresses network blind spots, significantly enhancing customer satisfaction.
What innovations has KT achieved by integrating AI and 5G?
KT has seamlessly integrated AI with 5G, expanding its role beyond telecommunications to a comprehensive digital platform. For example, KT’s AiON which combines AI with SDN technology, analyze network traffic in real time, providing automated optimization solutions and enhancing operational efficiency. This system ensures seamless operations in complex environments such as large factories or hospitals, where real-time monitoring is critical to avoid disruptions.
Furthermore, KT’s AI-based robotic solutions are transforming service delivery across industries. Robots in hotels handle room guidance and item deliveries, while in hospitals, they assist with medication transportation and patient navigation. These solutions not only enhance operational efficiency but also provide personalized interactions for a superior customer experience.
KT’s voice-based AI assistant, GiGA Genie, is widely used in both households and businesses, while Rangtalk facilitates efficient communication between teachers and parents in educational settings. These applications generate transformative value in everyday life and work environments, showcasing KT’s commitment to innovation.
How is KT using 5G technology to achieve its ESG goals?
KT places sustainability at the core of its mission, integrating ESG management into its operations. To achieve carbon neutrality (Net Zero) by 2050, KT has developed a four-pillar strategy: transitioning to decarbonization, innovating eco-friendly value chains, improving energy efficiency, and strengthening climate management capabilities. These efforts aim to reduce greenhouse gas (GHG) emissions by 51.7% by 2030 compared to 2021 levels.
Supporting these objectives, KT optimizes its network infrastructure and accelerates its transition to renewable energy. It has also partnered with suppliers to create a low-carbon supply chain. Additionally, KT promotes resource efficiency through initiatives like producing Genie A set-top boxes with recycled materials and running IT equipment recycling campaigns.
Digital inclusion is another priority. KT provides IT education and resources to underserved communities, offering digital literacy programs for children, technology training for seniors, and other initiatives aimed at closing the digital divide.
How does KT plan to further develop its 5G technology in the future?
KT aims to enhance its 5G technology to deliver richer experiences and greater value for both individual and enterprise customers. By leveraging VoNR (Voice over New Radio), KT enables ultra-fast data transmission and high-quality voice calls, paving the way for immersive applications such as AR, VR, and the metaverse. These technologies will extend beyond entertainment to areas like telemedicine and smart education.
Additionally, KT is building a dedicated 5G network for Urban Air Mobility (UAM), combining terrestrial base stations with low-Earth orbit satellites to eliminate service blind spots and ensure robust communication for next-generation mobility solutions.
KT is also advancing global telecommunications standards through Open RAN technology, fostering interoperability among equipment manufacturers and driving cost efficiency. These innovative strategies position KT as a leader in the global 5G ecosystem.
