South Korea plans to invest $1.5 billion US in a next-generation 5G wireless service, Agence France-Presse reported Wednesday. AFP said South Korea would implement the technology, which would be fast enough to allow users to download a full-length movie in a second, within six years. "We helped fuel national growth with 2G services in the 1990s, 3G in the 2000s and 4G around 2010. Now it is time to take preemptive action to develop 5G," AFP quoted the South Korean science ministry as saying in a statement. The ministry said it believes there will be "fierce competition in this market" within "a few years" as European countries, as well as China and the U.S., are “making aggressive efforts to develop 5G technology.” South Korea plans to roll out a trial service in 2017, and make the service fully commercially available in December 2020, AFP said.
