高速60千兆赫無線連接終于起飛

　　本文著眼于60 GHz頻段超高頻無線系統的最新發展。一系列新的設備正在開發的公司如Wilocity和peraso技術，可以提供超高速、短距離的數據鏈接和行業現在一個產業集團支持的一個標準。

　　今年，新一代高速無線技術終于上市。在過去的十年里，60千兆赫的無線通信的發展是不斷上升的——IBM在2006顯示了工作收發器，但是2013的第一個月的一些發展已經開始將這項技術推向實際應用。超高速Wi-Fi的承諾已經存在了好幾年，但現實世界的應用程序一直是不確定的。雖然有四家初創公司致力于60 GHz技術，但沒有人愿意重復上次高速無線標準超寬帶（UWB）的斗爭。超寬帶提供高速連接但兩不同規格沒有全球標準，并逐步團體如WiMedia聯盟和無線USB消失。

　　The 60 GHz technology used for the latest wireless systems provides very high speeds， but at short distances， as the signal is easily absorbed by water and other materials. This means the technology is more suited to short， high-speed point-to-point connections， and the first major target is replacing the HDMI cable that carries high definition and 3D TV signals from the set top box to a large screen TV. However， it is the opportunity to put this technology into a smartphone and other portable devices that drive the current interest in the market – being able to transfer HD video to a TV screen for display is seen as a compelling application.

　　All this is leading to predictions of a market of over 1 billion units a year by 2017， says market research company ABI Research.
