SK Telecom (NYSE: SKM, hereinafter referred to as “SKT”) today announced that it developed and applied a system that checks the safety of cell towers using drones and image analysis AI. Developed by SKT’s in-house experts, the image analysis AI model is capable of determining the status of bolts and nuts by analyzing images taken by drones. Cell towers equipped with transmitting and receiving antennas are installed all across the nation and reach a height of up to 75 meters. And since these cell towers require periodic maintenance to prevent accidents caused by deterioration, such as corrosion or loosening of bolts and nuts, specialized personnel had to climb up the cell towers or study the images of cell towers taken by drones to visually check the conditions. Now with the intelligent safety inspection system in place, SKT can not only prevent accidents due to aging cell towers, but also can secure the safety of these personnel by minimizing the need to go up the cell towers. Moreover, the company can drive up work productivity through the application of an AI model that automatically identifies defects by analyzing images taken by drones. Previously, safety inspectors had to study around 100 images to complete safety inspection of one cell tower. With the adoption of this AI analysis model, SKT was able to reduce the time required for the process by 95%, while increasing the reliability and consistency of the analysis results. Going forward, SKT plans to keep advancing the intelligent safety inspection system for cell towers by adding inspection items such as wind pressure safety/inclination, further improving the AI model and linking it with the safety management system. In addition to the drone-based intelligent safety inspection system, SKT is also actively applyingAI to all areas related to its telecommunications networks, including equipment error/anomaly detection, power cost reduction, and work completion inspection. “By building an intelligent safety inspection system that can complement the existing visual inspection, we have secured greater safety for workers,” said Park Myung-soon, SKT’s Vice President and Head of Infra DT Office. “We will continue to make efforts to achieve AI transformation of our telecommunication networks, while focusing on developing our field workers into experts who can develop and operate AI.”

SKT will operate a joint exhibition booth with SK Inc., SK Innovation, SK hynix, SK E&S, SK Ecoplant, SK Biopharmaceuticals and SKC under the theme of ‘SK’s Actions for 2030 Net Zero,’ which highlights their commitment to reducing carbon emissions by about 200 million tons by 2030. The joint exhibition booth will cover an area of 1,200 square meters in the Central Hall, and eight SK affiliates will showcase diverse technologies and products under the theme. SKT will be displaying Urban Air Mobility (UAM), AI semiconductor ‘SAPEON,’ and Virtual Power Plant (VPP) for renewable energy. Its booth will feature a life-sized UAM aircraft to enable visitors to experience how the SAPEON chip can help enhance the UAM aircraft operation, and how VPP will supply power to vertiports. Upon boarding the UAM aircraft, visitors will find themselves virtually flying over the skies of Busan. SAPEON mounted on the aircraft will support both the pilot and ground control by monitoring the air route, aircraft surroundings, and the situation within the aircraft, and identifying risk factors; and VPP will predict power demand and supply, and supply environmentally-friendly energy to the UAM aircraft and vertiport. UAM is being highlighted as an eco-friendly means of transportation that can be connected to various means of land transportation. As a member of ‘UAM Team Korea,’ a public-private consultative body organized by the Ministry of Land, Infrastructure and Transport, SKT is accelerating the commercialization of UAM through cooperation with strong domestic and foreign partners. It signed a memorandum of understanding (MOU) with Hanwha Systems, Korea Airports Corporation, and Korea Transport Institute in 2021, and entered into a strategic partnership with Joby Aviation, a global leading aviation company developing electric vertical takeoff and landing (eVTOL) air vehicles, in 2022. SKT developed an AI semiconductor SAPEON and secured a bridgehead to advance into the global market by establishing SAPEON Inc. in the U.S., through joint investment with SK Square and SK hynix. SAPEON X220 is optimally designed to process AI tasks faster, using less power by efficiently processing large amounts of data in parallel. It is environmentally friendly, as it is 1.5 times faster and consumes only 80% of the power compared to Graphics Processing Units (GPUs). Recently, SAPEON X220 was recognized for its excellence by recording 2.3 to 4.6 times higher performance than the existing products in the MLPerf benchmark, a global AI research consortium. SAPEON Inc. plans to release its successor model 'X300' series products with improved performance and computational accuracy in 2023. SKT’s VPP is a system that enables integrated management of renewable energy produced on a small scale in different regions by individuals or businesses. In September, SKT signed an MOU with SK Energy, Korea Electrotechnical Research Institute, and startups to develop future virtual power plant technology. By utilizing ICT including AI, SKT plans to build a VPP optimized for producing, storing and trading renewable energy based on the prediction of energy demand and supply. “At this year’s CES, we will be introducing innovative green ICT that can accelerate our progress towards achieving Net Zero, and invite the world to join us on this journey,” said SKT.
