This week, South Korea’s science ministry announced plans to invest a whopping $1.5 billion in building a nationwide 5G wireless service. Once developed, the network will permit Gigabit transmissions on compatible mobile devices. That’s fast enough to download an entire movie in one second, or about 1,000 times faster than existing 4G LTE networks.Of course, a project like this will take time—six years, according to a statement released by the ministry. But a trial service could be rolled out in certain markets by 2017.
