Samsung achieves 'a movie a second' 5G wireless speed

Samsung Electronics said it had successfully tested super-fast fifth-generation (5G) wireless technology that would eventually allow users to download an entire movie in one second.

The South Korean giant said on Monday the test had witnessed data transmission of more than one gigabyte per second over a distance of two kilometres.

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, it said. That will permit users to "transmit massive data files including high quality digital movies practically without limitation".

"As a result, subscribers will be able to enjoy a wide range of services such as 3D movies and games, real-time streaming of ultra high-definition (UHD) content, and remote medical services," it said.

Samsung added it had found a way to harness millimetre-wave bands which have proved to be a sticking point for the mobile industry to date.
