Samsung has wireless technology in the works that will let users download an entire movie in a second, it says. In tests, the South Korean company's 5G service worked over a distance of more than a mile, AFP reports via Business Insider. Data traveled at more than a gigabyte per second, the firm says. It's "up to several hundred times faster" than current 4G systems. But don't get too excited yet: The service won't go commercial until at least 2020. When it does, though, we can expect "3D movies and games, real-time streaming of ultra high-definition content, and remote medical services," the company says.
