SK Telecom maximizes the efficiency of communication services and AI services and presents new values and possibilities through various technologies such as AI base stations, AI routing, and communication and sensing integration.

SK Telecom will showcase network AI technology that uses AI to increase the value of mobile networks at 'MWC25 (Mobile World Congress 2025)' held in Barcelona, Spain.

At this year's MWC exhibition hall, SKT will demonstrate 'AI-RAN' technology, which enables the provision of both communication and AI services by applying various chipsets including GPUs to general servers. This is a method of implementing communication services and AI workloads simultaneously at an AI base station.

Telecommunication base stations usually secure spare resources in case of heavy traffic, but AI base stations allocate resources so that these spare resources can be used for AI inference services, etc. This can maximize AI service efficiency.

The exhibition also includes a technology (AI Orchestrator) that provides AI service environments to customers by integrating and managing AI infrastructure distributed across Edge AI countries, and a case study on improving communication quality with AI-based network analysis functions (NWDAF).

SKT is introducing 'AI Routing' technology that reduces the load on servers required for AI services by processing simple AI tasks with on-device AI. This is a technology that determines in real time which of the servers equipped with Large Language Models (LLM) and devices equipped with Small Language Models (SLM) can provide the best inference performance and assigns the subject to be serviced.

Customers can experience the low latency advantage of on-device AI while maintaining the highest possible service quality, and AI business operators can also improve operational efficiency by reducing server load.

SK Telecom is also introducing 'Integrated Sensing and Communication (ISAC)' technology that utilizes communication frequencies as sensors.

ISAC is a technology that collects information about the surrounding environment using radio signals. It can precisely detect the surroundings by analyzing the degree to which communication frequency signals transmitted from base stations or terminals are reflected by people or objects.

These technologies can be applied to public safety and industrial automation in mobile communication networks.

SK Telecom’s Ryu Tak-ki, head of the Infrastructure Technology Division, said, “As we have presented the direction of network evolution where communications and AI are converged through the 6G white paper and other publications, we plan to showcase our advanced technologies related to AI wired and wireless infrastructure that add new value to infrastructure at this MWC.”
