Millimetre-wave WiFi devices.

Samsung preps 4.6Gbps millimetre-wave WiFi devices.

Known as WiGig, the 802.11ad standard transmits in the unlicensed 60GHz frequency band for high performance up to 4.6 gigabits per second in Samsung's designs, while remaining backwards compatible with the previous 2.4GHz and 5GHz Wi-Fi standards.

Compared to today's 802.11ac which provides a maximum throughput of 867 megabits per second per stream under ideal conditions, 802.11ad devices can reach speeds as fast as 7 gigabit/s.

The high frequency used for WiGig results in path loss and poor wall and floor penetration of the signal, leading to shorter reach than existing Wi-Fi.

Samsung said it has solved these issues with millimetre-wave circuit design, improved transmission technology and a wide-coverage beam-shaping aerials. This, the company said, would make WiGig commercially viable in retail devices.
