This training utilizes SFC, an on-site communication platform developed by KT. SFC is an application that consolidates and manages the status of wireless and transmission facility restoration among KT, its affiliates, and facility partners during disasters and emergencies. By preventing duplicate dispatches and enabling real-time monitoring of restoration progress, it facilitates efficient collaboration. KT plans to use SFC to respond quickly to future disaster situations.

KT is also advancing its 'Supercell' technology, which is expected to be highly effective in disaster scenarios. Supercell is a next-generation communication technology that covers both terrestrial and aerial domains, combining high-performance lens antennas with non-terrestrial network (NTN) technology to provide much wider coverage than conventional systems. Last year, KT installed Supercell high-altitude base stations in mountainous, island, and maritime regions where access to existing terrestrial infrastructure is difficult. Going forward, the company plans to gradually expand the scope of disaster safety communication networks by utilizing high-altitude platforms and low-orbit satellites.

Lee Jongsik, Head of KT Future Network Lab, stated, "As a key telecommunications operator providing universal communication services, KT will continue to advance its technologies to ensure uninterrupted communication services during disasters," adding, "We will prepare for the evolution toward 6G ubiquitous networks by advancing satellite and other non-terrestrial network technologies."
