Samsung Electronics has signed AI-RAN agreements with KT and SK Telecom, putting Korea's largest network vendor inside the design conversation for the country's eventual 6G architecture, according to Asia Business Outlook. The deals — disclosed with limited public detail — cover what Samsung characterises as AI-RAN, an emerging framework that folds artificial-intelligence processing into the radio access network rather than treating it as a separate IT layer.

What the contracts actually contain in dollar terms, deployment volumes, or trial dates remains undisclosed in the announcement circulated by the outlet. Samsung's network business has not filed a regulatory disclosure that would clarify the commercial weight of the pacts, and neither carrier has detailed which spectrum bands, sites, or AI workloads the work will cover.

For Samsung, the strategic logic is straightforward. The vendor supplies 4G and 5G core and RAN kit to both KT and SK Telecom and remains the dominant domestic alternative to Nokia, Ericsson, and Huawei in Korea. Securing early AI-RAN design wins with its home carriers gives the company a reference customer and a testbed for the same pitch it will take to operators in the United States, Japan, and Europe.

For KT and SK Telecom, the calculus is more layered. Both carriers are still mid-rollout on 5G standalone, and both are trimming capex to defend margins in a saturated mobile market. Spending on pre-6G research keeps engineering teams employed and a public R&D narrative alive without committing to a full 6G build — something neither operator has a commercial timetable for.

What does AI-RAN actually change?

The label covers a spectrum of work, from AI-assisted radio resource management to running inference workloads on the same general-purpose hardware that hosts the baseband. The most aggressive version — pushed by Nvidia and a coalition of operators under the AI-RAN Alliance — points the radio stack itself toward AI-native designs. Samsung has so far aligned itself with the more conservative reading: using AI to optimise scheduling, beamforming, and energy use on existing 5G hardware.

A skeptic would note that "AI-RAN" in 2025 still reads as more marketing wrapper than standardised product. The 3GPP has not defined an AI-RAN architecture in Release 18 or Release 19, and vendor claims about AI-driven spectral efficiency gains typically rest on internal simulations rather than third-party field trials.

Where does Korea's 6G roadmap stand?

The Korean government published a 6G R&D roadmap in 2023, targeting commercial launches in the 2028–2030 window with a focus on terahertz research, AI-native air interfaces, and satellite integration. Samsung holds a heavy share of the patent filings emerging from that programme, alongside LG and the country's network operators. The KT and SK Telecom pacts extend that pattern from the lab into vendor-carrier collaboration, but stop well short of a procurement commitment for a 6G radio access network that does not yet exist commercially.

The question that matters is whether these agreements translate into paid trials once 6G specifications firm up — likely in the second half of this decade — or whether they remain R&D cost centres amortised across the two operators' existing 5G books.

The data point to watch next is whether KT or SK Telecom discloses a capex line item attributable to AI-RAN in their 2025 or 2026 annual reports, and whether Samsung names any foreign operator as an AI-RAN customer before the year ends.
