South Korea, already one of the most wired countries on earth, Wednesday announced a 1.6 trillion won ($1.5 billion) plan to roll out a next-generation 5G wireless service quick enough to download full-length films in a second. The science ministry said it aims to implement the technology — about 1,000 times faster than the 4G services currently available — within six years. Countries in Europe, China and the US are making aggressive efforts to develop 5G technology … and we believe there will be fierce competition in this market in a few years, it said. Under the roadmap, a trial 5G service will be rolled out in 2017 and a fully commercial service in December 2020.
