Case Study: KT Corporation achieves rapid LTE rollout and 1.4M subscribers with Samsung

KT Corporation - Customer Case study

KT Corporation, Korea’s largest communications provider (87% fixed-line share, 31.1% mobile share), faced the challenge of being a late entrant to the LTE market (launching in January 2012) and needed to deploy a high-capacity LTE network quickly to catch up with rivals. To meet this urgency and leverage its extensive fiber infrastructure, KT Corporation selected Samsung’s Smart LTE Network solution, including the virtual cloud Smart Scheduler and plug‑in radio units.

Samsung implemented its Smart LTE Network as a fast, simple “plug‑in” deployment tied into KT’s fiber, with the Smart Scheduler optimizing radio resources across hundreds of cells to reduce CAPEX and OPEX (energy, maintenance, site rental). The result: KT rolled out 10,000 radio units in one month, rapidly scaled LTE coverage, and grew LTE subscribers to over 1.4 million — a measurable acceleration in deployment and competitive catch‑up enabled by Samsung.
