Samsung Electronics said Sunday that it has developed a 60GHz technology for a faster wireless fidelity (WiFi) network, whose Internet access it claims is more than five times faster than the current WiFi access.
Samsung said the new WiFi technology allows users to download and upload data at speeds of up to 575 megabits per second (Mbps), compared to the currently available 108 Mbps. As a result, a 1GB movie will take less than three seconds to transfer between devices, while uncompressed high-definition videos can easily be streamed from mobile devices to TVs in real-time without any delay.
"Samsung has successfully overcome the barriers to the commercialization of 60GHz millimeter-wave band Wi-Fi technology, and looks forward to commercializing this breakthrough technology," said Kim Chang Yong, Head of DMC R&D Center of Samsung Electronics.
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 new 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.
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.
In addition, Samsung also enhanced the overall signal quality by developing a first micro beam-forming control technology that optimizes the communications module in less than 1/3,000 seconds, in case of any changes in the communications environment. The company also developed a method that allows multiple devices to connect simultaneously to a network.As is the case with the 2.4GHz and 5GHz spectrum, the 60GHz is an unlicensed band spectrum across the world, and commercialization is expected as early as next year. Samsung plans to apply this new technology to a wide range of products, including audio visual and medical devices, as well as telecommunications equipment. The technology will also be integral to developments relevant to the Samsung Smart Home and other initiatives related to the Internet of Things.
