Business
CS Corporation is a South Korea-based telecommunications equipment and electronic materials manufacturer primarily engaged in the development, production, and distribution of mobile network coverage systems and wireless infrastructure solutions. Founded in 1999 as C&S Microwave Co., Ltd. and headquartered in Seongnam-si, South Korea, the company operates across core business divisions encompassing telecommunications equipment, organic light-emitting diode (OLED) materials, and specialized broadcasting technologies. The company’s comprehensive product and service portfolio includes radio frequency (RF) repeaters, optical repeaters, and outdoor base station repeaters for cellular network expansion; in-building distributed antenna systems (DAS), point of interface (POI) units, master units, and optical hub and remote units supporting 3G, 4G LTE, and 5G communications; residential home repeaters and wireless broadband coverage extenders; digital television (DTV) repeaters and digital multimedia broadcasting (DMB) transmission equipment; organic chemical materials utilized in OLED display manufacturing processes; and voice recognition modules alongside telecom network installation, maintenance, and system integration services. CS Corporation serves major tier-one mobile network operators, including SK Telecom, KT, and LG Uplus, as well as international carriers and display panel manufacturers across South Korea, North America, and Asia. In recent operational and strategic developments, the company completed the 100% equity acquisition of Mirae Information Technology for KRW 20 billion to expand its technology assets and business scope. Additionally, the company executed a 2-for-1 share consolidation to optimize its capital structure, completed the early redemption of its sixth series convertible bonds, and secured successive supply contracts for next-generation 5G optical repeaters and network infrastructure components.
