SK Telecom has deployed a private 5G network to power a smart office for Hana Financial Group, marking the latest move by Korea's largest mobile operator to expand beyond consumer services into enterprise-specific wireless deployments.

The project, reported by Seoul Economic Daily, equips the financial group's office environment with a dedicated 5G infrastructure rather than relying on public network coverage or indoor Wi-Fi. Private 5G networks of this kind use locally licensed or reserved spectrum to give enterprises control over connectivity, security and quality of service within their own premises — a priority for financial institutions handling sensitive customer data.

For SK Telecom, the Hana Financial contract extends a private network business line the operator has been building since Korean regulators opened the way for enterprises and operators to run dedicated 5G systems. Korea has been among the more active markets in Asia for private 5G, with the country's major operators — SK Telecom, KT and LG U+ — each pursuing enterprise deployments in manufacturing, logistics, ports and the public sector.

The smart office application itself targets internal operations: private 5G's low latency and high capacity can support dense deployments of connected devices, real-time collaboration tools and building-management systems without competing for capacity on the public macro network. Financial firms have been relatively cautious adopters of private wireless compared with manufacturers, which makes a deal with one of Korea's largest financial groups a notable reference win for SK Telecom in a vertical where security accreditation and reliability requirements are demanding.

Hana Financial Group, headquartered in Seoul, spans banking, securities and insurance businesses. The deployment positions the group among Korean enterprises using dedicated 5G rather than conventional enterprise Wi-Fi for mission-internal connectivity — a shift operators across the region are pushing because private network contracts carry higher average revenue per account than consumer mobile lines.

The deal also fits SK Telecom's broader enterprise strategy. The operator has pinned part of its growth plan on business-to-business revenue, including private 5G, as the Korean consumer mobile market saturates and 5G subscription growth slows. Contracts with large institutions such as Hana Financial give the operator anchor customers it can use to market similar deployments to other financial, healthcare and public-sector organizations.

Commercial terms of the contract, including its value and duration, were not disclosed in the report, and neither company has published subscriber or throughput figures for the network. The deployment's scope — whether it covers a single headquarters building or multiple sites across the group — also remains unspecified.

What is clear is the direction: SK Telecom continues to convert Korea's early 5G leadership into enterprise revenue, one vertical at a time. Expect further private 5G contract announcements from the operator as it targets finance and other data-sensitive industries in the coming quarters.
