How Integrated Sensing and Communication Works

ISAC technology leverages existing communications infrastructure to collect information about surrounding environments without dedicated equipment2

. By analyzing wireless signals transmitted by base stations as they reflect off nearby objects, ISAC can detect an object's speed, distance, and direction of movement1

1

. This means a cell tower could detect a drone, track a vehicle, or monitor foot traffic without any dedicated sensing hardware1

1

. Environmental sensing today relies on separate systems—LiDAR uses laser light to measure distance, while radar systems use radio waves, both requiring independent hardware that must be installed, powered, and maintained1

1

. Base station-based sensing eliminates that requirement by piggybacking on wireless infrastructure that mobile operators have already built1

Testing Plans for 6G Sensing Technology

The collaboration will initially focus on human detection for safety applications and improving network operational efficiency1

. The two companies plan to validate ISAC performance on LG Uplus's existing 5G networks first, then move to the 7 GHz band, a candidate frequency for 6G that offers a balance between wide coverage and high bandwidth1

1

. Over time, the partnership will combine ISAC-generated wireless data—including location, speed, and density information—with camera imagery to improve detection accuracy through multimodal AI models that integrate diverse forms of sensing data1

Why 6G Commercialization Depends on ISAC

The International Telecommunication Union Radiocommunication Sector has designated Integrated Sensing and Communication as one of six usage scenarios for IMT-2030, the formal name for 6G1

1

. This inclusion signals that next-generation mobile networks are being designed from the outset to sense the physical world, not just move data through it1

1

. By leveraging wireless signals, ISAC can identify objects beyond a camera's field of view and in low-light or nighttime conditions2

2

. These capabilities could enable new services that improve safety, efficiency, and productivity across consumer and industrial sectors, from drone tracking to traffic monitoring and weather changes2

2

. LG Uplus previously identified ISAC as a core pillar of future 6G networks in a white paper released last year, and the technology has emerged as one of the most closely watched concepts because it could expand networks beyond communications into areas such as mobility and smart infrastructure3

Strategic Positioning for Global 6G Standards

Samsung has been building its 6G credentials methodically, publishing a 6G white paper outlining its vision for AI-native and sustainable communications, demonstrating technologies at the Silicon Valley Future Wireless Summit in November 2025, and showcasing AI-RAN capabilities at Mobile World Congress in March 20261

. The ISAC collaboration with LG Uplus extends that work from lab demonstrations to field validation on a live commercial network1

1

. The 7 GHz band is increasingly described as the "golden band" for 6G because it offers enough bandwidth for high-speed data while still propagating far enough for practical coverage, with South Korea actively exploring the 7.125 to 8.4 GHz range as a primary candidate1

1

. The allocation decisions at the World Radiocommunication Conference in 2027 will largely determine which countries have the spectrum to deploy 6G at scale, making this partnership strategically important for South Korea's position in global tech supply chains1

1

. According to JinGuk Jeong, Executive Vice President at Samsung Research, "ISAC is a core technology that transforms communications networks into sensing platforms, enabling users, network operators and industries to experience the full value of 6G"2

2

. Commercial 6G deployment is not expected until the early 2030s, but this collaboration positions both companies to influence emerging standards while testing whether environmental sensors embedded in cellular infrastructure can deliver on their promise in real-world conditions1
