Want faster Wi-Fi? Samsung Electronics Co. is claiming a breakthrough that will bring five times greater Wi-Fi speeds to allow the transfer of a 1-gigabyte movie in three seconds or less.

Samsung said Sunday 60-gigahertz technology should be ready for commercialization in 2015 and it should be available on several products, including smartphones, tablets and TVs as well as medical devices and telecommunications equipment.

The technology allows the transfer of 575 megabytes per second, which will allow uncompressed high-definition videos to be streamed from mobile devices to TVs in real time without buffering.

The current 802.11ac Wi-Fi standard supports transfer up to 108 megabytes per second, which allows for functionality like video streaming, wireless docking and wireless storage on a single device. But 60 GHz Wi-Fi would specifically allow for faster transfer speeds among several devices.

The Korean manufacturer says it has been able to bridge the gap between theoretical speeds and practical speeds. Every Wi-Fi router has speeds that it could reach if not interrupted by its maximum network bandwidth. Samsung’s technology essentially takes away the mechanism that caps transfer speeds.

Until now, there have been significant challenges in commercially adopting 60GHz Wi-Fi technology, as millimeter waves that travel by line-of-sight has weak penetration properties and is susceptible to path loss, resulting in poor signal and data performance. By leveraging millimeter-wave circuit design and high performance modem technologies and by developing wide-coverage beam-forming antenna, Samsung was able to successfully achieve the highest-quality commercially viable 60GHz Wi-Fi technology.
