Samsung Research has emerged as one of the most aggressive players in the race toward 6G, combining record-breaking laboratory demonstrations with concrete architectural proposals. From achieving terahertz data links exceeding 140 Gbps to publishing detailed white papers on next-generation network design, the South Korean giant is positioning itself to shape 6G standards as decisively as it shaped 5G before them.

Samsung's 6G Timeline and Vision

Samsung published its first comprehensive 6G white paper in July 2020, making it one of the earliest major vendors to lay out a concrete vision for the next generation. The company projects initial 6G standardization by the 3GPP Release 22 timeframe around 2028, with commercial deployments beginning between 2030 and 2032. Samsung's 6G vision centers on three pillars: hyper-connectivity with peak rates up to 1 Tbps, sub-millisecond latency under 100 microseconds, and AI-native network intelligence embedded at every layer.

In its updated 2024 white paper, Samsung refined this vision to emphasize what it calls the "Next Hyper-Connected Experience" — a convergence of extended reality (XR), digital twins, and holographic communication that demands network capabilities far beyond what 5G Advanced can deliver. The company estimates that 6G networks will need to support 10 million devices per square kilometer, a tenfold increase over 5G specifications.

Terahertz Prototypes and Lab Records

Samsung's Advanced Communications Research Center in Suwon has produced several breakthrough demonstrations in terahertz communications. In 2023, the team achieved a 140 Gbps data link at 135 GHz over a 100-meter indoor distance, using a custom-designed phased array with 16 antenna elements. This remains one of the highest data rates demonstrated at sub-THz frequencies over meaningful distances.

By mid-2025, Samsung demonstrated adaptive beamforming at 220 GHz with 64-element arrays, achieving 50 Gbps at 200 meters outdoors. The prototype used Samsung's proprietary gallium nitride (GaN) amplifier technology, which the company claims offers 3x the power efficiency of competing silicon-germanium approaches. These results are particularly significant because they address the primary objection to THz communications — limited range — by demonstrating viable outdoor links at distances relevant to small-cell urban deployments.

AI-Native RAN Architecture

Samsung's 6G architecture proposals go beyond incremental improvements to 5G. The company's AI-RAN framework, first presented at MWC 2025, embeds machine learning models directly into the radio access network stack. Rather than treating AI as an overlay optimization layer, Samsung proposes three tiers of AI integration:

  • PHY-layer AI — neural network-based channel estimation and decoding that replaces traditional LDPC decoders, achieving 15-20% throughput gains in Samsung's lab tests
  • MAC-layer AI — reinforcement learning schedulers that adapt resource allocation in real-time based on traffic patterns, reducing latency by up to 40% compared to proportional fair scheduling
  • Network-layer AI — federated learning across base stations for interference management and handover prediction, cutting handover failures by 60% in Samsung's multi-cell testbed

Samsung has implemented portions of this architecture in its vRAN 3.0 platform, currently deployed by operators including T-Mobile US, KDDI Japan, and SK Telecom. The production version uses a simplified AI scheduler that Samsung claims delivers 12% spectral efficiency improvement over its non-AI predecessor.

ISAC: Integrated Sensing and Communication

A key differentiator in Samsung's 6G strategy is its investment in Integrated Sensing and Communication (ISAC). The concept uses the same waveform and hardware for both data transmission and radar-like sensing, effectively turning every base station into a multi-function sensor. Samsung's prototype, demonstrated at Samsung Tech Day 2025, achieves centimeter-level positioning accuracy and can detect objects at distances up to 500 meters using standard OFDM waveforms at 28 GHz.

Samsung sees ISAC as critical for autonomous vehicle support, smart city infrastructure, and industrial IoT. The company has filed over 200 ISAC-related patents since 2022, representing roughly 15% of its total 6G patent portfolio. Samsung's ISAC working group is actively contributing to 3GPP Study Items on integrated sensing for Release 19 and beyond.

Reconfigurable Intelligent Surfaces

Samsung has invested heavily in Reconfigurable Intelligent Surfaces (RIS), which use electronically controlled metasurface panels to reflect and steer radio signals without active amplification. In collaboration with Seoul National University, Samsung demonstrated a 1,024-element RIS panel at 28 GHz that improved coverage in non-line-of-sight scenarios by 25 dB — enough to convert a coverage hole into a viable connection point.

The company's RIS roadmap envisions transparent panels integrated into building windows and walls, creating a "smart radio environment" that dynamically adapts to user locations and traffic demands. Samsung estimates that RIS deployment could reduce the number of required small cells in urban areas by 30-40%, significantly lowering network deployment costs for operators.

Standards Leadership and Patent Portfolio

Samsung holds one of the largest 6G patent portfolios globally, with over 1,400 patent families filed across key technology areas including THz communications, AI-RAN, ISAC, and RIS. According to the European Telecommunications Standards Institute (ETSI), Samsung ranked among the top three 6G patent holders in 2025, alongside Huawei and Nokia.

The company chairs or vice-chairs multiple ITU-R and 3GPP working groups relevant to 6G, including the ITU-R Working Party 5D subgroup on IMT-2030 vision requirements. Samsung's standardization strategy focuses on ensuring its technology contributions — particularly in AI-RAN and ISAC — become foundational elements of the 6G standard rather than optional features.

Commercial Strategy and Deployment Outlook

Samsung's 6G commercialization strategy leverages its unique position as both a network equipment vendor and a consumer device manufacturer. The company plans to develop integrated 6G modem-RF systems for smartphones using its Exynos platform, potentially giving it a time-to-market advantage similar to what Qualcomm achieved with early 5G modems.

On the infrastructure side, Samsung is expanding its Open RAN portfolio with 6G-ready architectures. The company's partnership with major US operators, particularly its $6.6 billion contract with Verizon signed in 2020, provides a direct path to early 6G network trials. Samsung has publicly committed to delivering 6G trial equipment to three operators by 2028, with pre-commercial systems available by 2029.

With over $3 billion invested in 6G R&D since 2019, Samsung is making a strategic bet that its combination of component expertise, network infrastructure capabilities, and device manufacturing scale will make it the indispensable partner for operators deploying 6G networks worldwide.
