The Telecom & 5G theme groups Korean companies that run mobile and fixed-line networks or supply equipment, infrastructure, and services tied to fifth-generation wireless technology. Korean investors often treat these firms together because their earnings tend to follow subscriber trends, network build-out cycles, and regulatory decisions on spectrum and tariffs. The theme is typically discussed alongside broader 5G rollout news and the wider digital infrastructure sector.
