  Korea Telecom: Building a GiGAtopia (A)

  Shane Greenstein, Feng Zhu and Kerry Herman

  Korea Telecom (KT) has committed $4 billion in investments and R&D to build a GiGAtopia, essentially ushering in the next generation of mobile (5G) and wired infrastructure. CEO Dr. Chang-Gyu Hwang, and his team are considering which areas to prioritize in terms of new products and services in development. The top five sectors identified by KT’s team include the Internet of Things (including connected cars and smart city/homes), media, health, energy, and security and surveillance, which might provide some quick wins both in terms of revenues and market lead. Should KT develop solutions that could be exported to other countries? Should KT go all in across all five sectors, or select one or two to prioritize?
