Samsung says it has successfully tested super-fast 5G wireless technology that would eventually allow users to download an entire movie in a matter of seconds.

The South Korean electronics giant said the test had resulted in data transmission of more than one gigabit per second (Gbps) over a distance of two kilometres.

Samsung: Says 5G technology could download a movie in one second.

The new technology, which will not be ready for the commercial market before 2020 at the earliest, would offer transmitting speeds "up to several hundred times faster" than existing 4G networks, the company said in a statement.
