高速60千兆赫無(wú)線連接終于起飛

　　本文著眼于60 GHz頻段超高頻無(wú)線系統(tǒng)的最新發(fā)展。一系列新的設(shè)備正在開發(fā)的公司如Wilocity和peraso技術(shù)，可以提供超高速、短距離的數(shù)據(jù)鏈接和行業(yè)現(xiàn)在一個(gè)產(chǎn)業(yè)集團(tuán)支持的一個(gè)標(biāo)準(zhǔn)。

　　今年，新一代高速無(wú)線技術(shù)終于上市。在過(guò)去的十年里，60千兆赫的無(wú)線通信的發(fā)展是不斷上升的——IBM在2006顯示了工作收發(fā)器，但是2013的第一個(gè)月的一些發(fā)展已經(jīng)開始將這項(xiàng)技術(shù)推向?qū)嶋H應(yīng)用。超高速Wi-Fi的承諾已經(jīng)存在了好幾年，但現(xiàn)實(shí)世界的應(yīng)用程序一直是不確定的。雖然有四家初創(chuàng)公司致力于60 GHz技術(shù)，但沒(méi)有人愿意重復(fù)上次高速無(wú)線標(biāo)準(zhǔn)超寬帶（UWB）的斗爭(zhēng)。超寬帶提供高速連接但兩不同規(guī)格沒(méi)有全球標(biāo)準(zhǔn)，并逐步團(tuán)體如WiMedia聯(lián)盟和無(wú)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.
