Samsung makes Wi-Fi five times faster

60GHz spectrum technology ready for IoT.

By Ben Sullivan

Samsung has said that it has developed a way of transmitting data at speeds of up to 4.6Gbps, a five-fold increase from today’s consumer device speed of 866Mbps.

Samsung said that the 60-GHz Wi-Fi technology breakthrough will mean a 1GB movie will take less than three seconds to transfer between devices, and uncompressed HD videos can be streamed from mobile devices to TVs in real-time with no delay.

"Samsung has successfully overcome the barriers to the commercialisation of 60GHz millimetre-wave band Wi-Fi technology, and looks forward to commercialising this breakthrough technology," said Kim Chang Yong, Head of DMC R&D Center of Samsung Electronics.

The 60GHz spectrum is unlicensed, with commercialisation expected by 2015. Samsung is looking to capitalise the spectrum for its Smart Home platforms and other Internet of Things-related applications.

Samsung said that, until now, challenges afflicting the advancement of such technology included the 60GHz millimetre-waves’ weak penetration properties. But by leveraging millimetre-wave circuit design and high performance modem technologies and by developing wide-coverage beam-forming antenna, Samsung was able to successfully achieve commercially viable 60GHz Wi-Fi technology.

Unlike the existing 2.4GHz and 5GHz Wi-Fi technologies, Samsung’s 802.11ad standard 60GHz Wi-Fi technology maintains maximum speed by eliminating co-channel interference, regardless of the number of devices using the same network. By doing so, Samsung’s technology removes the gap between theoretical and actual speeds, and exhibits actual speed that is more than 10 times faster than that of 2.4GHz and 5GHz Wi-Fi technologies.
