Samsung Develops Five Times Faster 60Ghz Wi-Fi Technology
Samsung Electronics announced the development of its 60GHz Wi-Fi technology that enables data transmission speeds of up to 4.6Gbps, or 575MB per second, a five-fold increase from 866Mbps, or 108MB per second, the maximum speed possible with existing consumer electronics devices. 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. “New and innovative changes await Samsung’s next-generation devices, while new possibilities have been opened up for the future development of 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 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 the world’s 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 the world’s first method that allows multiple devices to connect simultaneously to a network.
