Wi-Fi 802.11ac to drive wireless HD
video in the home
Streaming high-definition video wirelessly
throughout your home will be a major benefit
of Wi-Fi 802.11ac in the next few years, says NPD In-Stat.
Expected to receive final approval by the IEEE toward the end of this year, 802.11ac will boast several improvements over 802.11n. The new wireless flavor will offer speeds surpassing 1 gigabit per second, almost three times that of 802.11n. It also promises to provide better coverage throughout an entire home with fewer dead spots.
802.11ac无线通信标准自称相对802.11n有了些许的升级，期待着在这一年结束时，期待着收到IEEE最后的批准。这个新的无限协议会提供1GB/s的速度，这大约是802.11n的三倍。她还保证提供一个对具有一无线死角的整个家庭更好的覆盖效果。
From a technical standpoint, the new standard will use such technologies as beamforming and higher amplitude modulation to send more data faster and more efficiently than 802.11n, NPD In-Stat analyst Gregory Potter told CNET. And 802.11ac will help smartphones and other mobile devices by providing higher bandwidth and a savings in power compared with 802.11n.
从技术的角度出发，这个新标准会使用一些诸如“波束成形”信号处理技术和“高振幅跳变”技术与802.11n相比，可以将更多的数据发送的更快和更有效。美国市场研究公司NPDIn-Stat的分析师Gregory Potter 告诉CNET。802.11ac还会帮助智能手机和其它移动设备提供较802.11n更高速的带宽和节能特性。
As 802.11ac starts to hit a variety of gadgets, including laptops, smartphones,tablets, and TVs, Potter sees high-definition video as the major beneficiary.
而且，802.11ac开始去冲击各种各样的小工具，包括掌上电脑；智能手机；平板电脑和电视，Potter 作为主要受益者，可以用它看HD（high-definition 高清）视频。
"The primary use case for consumers using 802.11ac is for video distribution," the analyst said late last week. "One scenario would be utilizing 802.11ac in a cable or satellite set top box for distribution of video to multiple televisions outside the main viewing area. Another would be utilizing 802.11ac on a smartphone to stream HD video directly to a television."
“对于消费者来说用802.11ac最主要的用处就是视频分享。”这位分析师上个星期说：“一个剧本会在一个有线电缆或者卫星机顶盒中，为了分享视频到主观看区域外的多电视终端而利用到802.11ac。另外802.11ac还会被用在智能手机将高清视频输出到电视机的场合。”
Once 802.11ac is approved this year, it will then be ready for certification by the Wi-Fi Alliance in early 2013, Potter explained. That will then pave the way for its full adoption by technology and consumer electronics companies.
一旦802.11ac在今年被批准，它会等待WiFi联盟在2013年初为其颁发证书，Potter解释到。那将接着为其走向技术生产和走向用户电子产品公司铺好路。
At first, though, the industry will likely release a slew of "draft" 802.11ac devices, just as was seen with Wireless-N. Several vendors already showed off some of their upcoming 802.11ac products atCES earlier this month, including Buffalo, which demoed its first wireless router powered by the new protocol.
首先，虽然工业会发布一个转型的测试的802.11设备，就像曾经看到的搭载无线-N网卡的一样。这个月早些时候在CES，已经有一些生产厂商已经展示了一些他们的即将生产的802.11ac设备，包括Buffalo，他测试了他们的以一个搭载新协议的无线路由样品机
The first smartphones sporting 802.11ac will pop up early in 2013, forec。asts Potter. Digital televisions adopting the new standard will also appear next year, with NPD In-Stat projecting more than 2 million 802.11ac-equipped TVs .
预计，第一款搭载802.11ac的智能手机会在2013年头面世。Potter说。采用这项新标准的数字电视任然会在明年出现，包括NPD In-Stat 公司设计的大于200万台配备802.11ac标准的电视。
But consumers will probably have to wait until around 2015 before 802.11ac really latches onto the market.
At that point, the analyst expects 802.11ac to appear in more than 18 million routers, 25 million TVs, 129 million tablets, 184 million notebooks, and 279 million smartphones. Altogether, around 1 billion devices equipped with the new standard are forecast to ship in another three years.
然而消费者可能必须要等到大约2015年，在802.11ac准备好投入市场的时候。在那个时候，分析师预计会出现使用802.11ac协议的0.18亿台路由，0.25亿台电视机，1.29亿太平板电脑，1.84亿台笔记本和2.79亿台智能手机。预计，总共加起来10亿台搭载新标准的设备会在接着三年内发售。
