1、5个顶尖4G应用本文指出了5个有可能随着4G无线网络的提速和扩容获得首次重要成功的流行应用，包括实时移动视频，在线游戏，基于云计算的应用，应用增强现实技术导航以及应急响应和远程医学。4G Killer Apps: A Top Five4G最受欢迎应用We identify five areas of technology where popular applications are likely to score their first major successes by exploiting the speed and capacity of the 4G wireless network
2、s to come.本文指出了5个有可能随着4G无线网络的提速和扩容获得首次重要成功的流行应用Imagine sitting on the grass in a shady park, watching flawless high-definition television on your connected tablet. Imagine pausing the program and switching over to a video call from your mother. 想象一下你正坐在绿树成荫的公园草坪上，用平板电脑看着流畅的高清电视。想象一下这时妈妈来电话了，你把节目暂停后转
3、成和妈妈进行视频通话。Wireless carriers will be trying to capture your imagination and your dollars with rosy scenarios like this one, tempting you with cool new applications-or better old ones-that fully exploit the 10X speed increases promised by fourth-generation (4G) wireless networks. 第四代（4G）无线网络将提供了10倍的速
4、度提升，这样的速度提升使得无线运营商将来会用与此类似的美好情景俘获你的想象力和银子，用新酷或者增强的应用来引诱你。Already, carriers like Sprint are extolling what they believe will be 4Gs killer apps, but at this point its a guessing game-and consumers will ultimately decide the winners. That said, it isnt too early to make educated guesses about where th
5、ose killer apps might surface-and here are ours. 运营商们比如Sprint正在宣扬他们认可的4G最受欢迎应用，但就目前这个阶段来说也只是猜猜的，消费者将最终决定哪个应用是赢家。既然这样的话，就让我们也来推测下哪些应用会最受欢迎。1. Live Mobile Video1，实时移动视频Today, most mobile phones come with advanced cameras that can even shoot video, so its no surprise that the next step in this area is
6、to link video apps to mobile networks. In the earliest stages, advances may be as simple as using an Apple iPhone or a Google Android-based device to upload a cute clip of your kid to YouTube. But already, specialized application providers like Qik are offering services that support live streaming v
7、ideo from your mobile device to the Internet, theoretically transforming anyone carrying a smartphone into an instant on-the-spot news reporter. 现在很多手机都配有能摄像的高级摄像头，这样的话把视频应用引入移动网络就不足为奇了。在初期大家可能只是简单的用Apple的iPhone或者使用基于Google Android系统的设备上传自家宝宝的一段视频。但也有专业的应用提供者，如QiK，提供支持手机到互联网的在线视频流服务，理论上可以把任何带着智能手机的人
8、立刻变成现场新闻记者。Though such services may not appeal to everyone, professional broadcast teams are sure to move to 4G services when they become available. Theoretically, at least, the WiMax and Long Term Evolution (LTE) 4G networks now being built will be able to handle broadcast-quality data loads over m
9、uch cheaper, faster, and more mobile connections than satellite trucks. One developer, Nomad Innovations, offers a WiMax-based modem that attaches to the back of a professional video camera, obviating the need for satellite connectivity in the field. 尽管这样的服务不会吸引到所有的人，但专业的广播团队一定会在4G服务可用后转而用之。至少在理论上，正
10、在建设的4G网络WiMax和LTE比起卫星的Trunk（端口汇聚）处理起广播级品质的数据来会成本更低且更快。开发者诺曼创新公司提供的基于WiMax的调制解调器，可以安装在专业的摄像机后部，这样就不需要现场有卫星连线了。Forward-facing cameras in products like Samsungs Mondi mobile Internet device (MID) and the forthcoming HTC EVO 4G (both of which both run on the Clearwire/Sprint WiMax network) herald a boom
11、 in personal, on-the-go videoconferencing over services like Skype or Oovoo. Thanks to Verizons recent deal to support Skype on its mobile devices, more people are likely to use the video capabilities of the popular Voice-over-IP program when Verizon launches its 4G network later this year. 终端上自带前置摄
12、像头的产品比如三星的新型MID，Mondi和即将推出的HTC EVO 4G（这两款产品都支持Clearwire或Sprint的WiMax网络），预示了使用Skype或OoVoo等服务的个人视频会议的蓬勃发展。由于Verizon近来在它的终端上支持了Skype，更多的人将会有可能使用这个流行的VoIP工具中的视频功能。2. Mobile/Portable Gaming2，在线游戏We expect gamers to develop a strong craving for the speed and mobility of 4G service. In the long term, onlin
13、e gamers may be the biggest users of portable 4G Wi-Fi routers like Sprints Overdrive and Clearwires Clear Spot, which receive swift 4G signals and then transmit them to gaming devices via a small Wi-Fi network. Since most gaming platforms have Wi-Fi connectivity built in, you can easily use the por
14、table modem to share a 4G connection with five to eight different devices (depending on which modem you buy). 我们认为游戏玩家们会对4G服务的速度和移动性有强烈的热情。长期来看，在线玩家有可能是4G WiFi路由器的最大用户群，像是Sprint的Overdrive和Clearwire的Clear Spot就是通过使用小型WiFi网络快速接收4G信号然后将其转到游戏终端。大部分的游戏平台都支持WiFi连接，你可以很容易地使用便携式调制解调器与5到8个（视你购买的调节解调器而定）不同的设备
15、分享4G连接。Using a portable pocket spot router to support ad hoc gaming parties over services such as Microsofts Xbox Live is an obvious way to take advantage of 4G networks. Likewise, the improved latency of 4G networks seems tailor-made for online gaming, where faster network response times can mean t
16、he difference between (virtual) life and death. The Sprint HTC EVO 4G WiMax phone is supposed to include a built-in Wi-Fi router that can support up to eight additional devices, enabling it to act as a portable broadband hub for gatherings of gamers. 在一些服务比如使用微软的Xbox Live上使用便携式的“口袋站点”路由器就可以玩转临时的游戏聚会
17、，这是一个明显应用4G网络优势的方式。同时，4G网络对潜伏期的改善似乎也是专门为在线游戏定制的，因为对于在线游戏玩家来说更快的网络响应速度意味着生死（虚拟的）差异。Sprint HTC EVO 4G WiMax手机内装了WiFi路由器，它可以支持8个额外的设备，使得此款手机可以用做便携式宽带集线器来聚集游戏玩家。 3. Cloud-Based Apps3，基于云计算的应用Expanded 4G network use will make cloud computing-working with data and apps that are stored online-even more app
18、ealing than it is today, especially for enterprise professionals who need access to transaction-heavy applications that reside mainly on the Internet, such as Ss CRM platform and various real-time collaboration platforms. If the broadband pipe from the cloud to the mobile device gets ten times fatte
19、r, cloud services will become considerably more reliable, functional, and secure for mobile users. 使用扩容的4G网络将使得云计算-用于在线存储的数据和应用-比今天更加吸引人，尤其是对企业里的专业人员来说他们需要接入网上交易繁忙的应用，如S的CRM平台和很多实时合作平台。如果从云到移动设备的宽带传输的管道变大10倍，云服务对于移动用户来说在可靠性，功能性和安全性方面都会有显著的改善。Though you may not think of them as such, Hulu and Netflix
20、 are cloud-based video services.And though they may not call it cloud computing, consumers of all types are likely to make heavy use of faster mobile connections to stream full-length television shows and movies from sites like H and N. 也许你并不认同Hulu和Netflix是基于云的视频服务，而且也许他们可能不管它叫做“云计算”，但各类的消费者都有可能大量的使
21、用更加快速的无线连接在像H和N这样的站点看未删节的电视节目和电影。Some college campuses are already exploring ways to combine 4G networks with portable computers or tablets like Apples iPad to replace physical textbooks. 很多大学已经在探索更多的能把4G网络和便携电脑或平板电脑，如Apple的iPad，进行融合方法来取代实物教科书。Magazine and newspaper publishers hope that 4G connectio
22、ns and new product designs (like the iPad) will allow them to charge for premium content, enriched with elements such as video and photos, that will require a faster broadband connection than the 3G link used to upload digital books to e-book readers like Amazons Kindle. 杂志和报纸出版社希望4G连接和新产品的设计（如iPad）
23、能使得他们对提供更多元素如视频和图片的高级内容收费，这就要求比3G连接更快的宽带连接以用于为电子书阅读器如Amazon的Kindle上传数字书籍。4. Navigation With Augmented Reality4，应用增强现实技术导航The Junaio augmented-reality application for mobile devices. Image: JunaioNavigation applications, which are typically married to expandable/zoomable maps such as Google Maps, are
24、 among the most popular downloads for 3G devices like the iPhone. With the promise of greater bandwidth on 4G networks, navigation application providers are already exploring the idea of augmented reality, in which a device will be able to present real-time visual data using a phones live camera and
25、 its positioning or GPS information. Junaio为移动设备提供的增强现实技术。想象一个这样的场景：JunaioNavigation，通常都是和譬如Google Maps捆绑在一起的，是3G设备如iPhone里最流行的下载之一。有了4G网络中更好的带宽，导航应用的提供商们已经开始探索“现实技术”这个想法了，用了这个技术设备就可以使用电话的实时摄像头提供实时的视频数据和它的位置或GPS信息。 End-user benefits range from modest-for example, the ability to point your phone down
26、 the street to see where the closest Starbucks is-to extremely powerful. As an example of the latter, imagine 4G-enabled helmets that can project a building infrastructure diagram onto a firefighters visor to help them make their way through a smoke-filled building. Augmented-reality navigation appl
27、ications will probably grow more popular and more widespread as in-car systems such as Fords Sync and General Motors OnStar permit integration between such apps and improved displays, antennas, GPS systems, and power plants inside vehicles. 终端用户获益范围从适度（比如有可以用你的手机看到最近的星巴克在那儿）到极强。举一个比较强的例子，想象一个可以有4G功能
28、的头盔放映一装大楼建筑图到消防员的面罩上，这能帮助他们在充满烟雾的大楼里面找到通路。增强现实导航技术将可能在车载系统中更加流行和得到广泛的应用，如福特的Sync和通用的OnStar中。在车载系统中可以将增强现实技术应用和显示、天线、GPS系统和车内供电系统更好的集成。5. Emergency Response and Telemedicine5，应急响应和远程医学Even before the FCC breaks ground on its proposed separate 4G network for first responders, you can expect local poli
29、ce departments, fire departments, and medical institutions to invest heavily in 4G-based systems aimed at providing better, faster, and less expensive medical and emergency care. 在FCC（联邦通信委员会）为它所提倡的独立4G网络破土动工第一批响应站之前，你就可以看到当地警察局，消防局和医疗机构把大笔的投资用于4G系统建设，其旨在提供更快更好且更廉价的医疗和紧急救援。Networking giant Cisco and
30、 service provider AT&T are already developing special gear and services for health-care operations, taking advantage of 4G networks ability to transfer large files (like X-rays) quickly, and to provide interactive video for remote physician monitoring and direction. The expected proliferation (and s
31、ubsequent cost reduction) for 4G deployments should also make it easier for rural communities to set up remote health centers, where doctors could visit patients via teleconference-like facilities. Ongoing government grants and stimulus funds should help pay for such civic-minded applications of 4G
32、technology. 网络巨人Cisco和服务提供商AT&T已经在为卫生保健应用开发独特的工具和服务，使用4G网络的能力来迅速传输大文件（像是X光片），为医生远程监督和指导提供互动视频。4G部署的繁荣发展（相继会带来成本降低）也会使得农村社区更加容易的建设远程医疗中心，医生可以通过视频会议为病患“看”病。正运作着的政府补助金和刺激基金应该用于资助4G技术中这样的热心于公益的应用。Paul Kapustka is editor and founder of Sidecut Reports, an independent research firm that specialzes in wireless technologies.Paul Kapustka是编辑兼Sidecut报道的创始人，Sidecut报道是一家致力于无线科技领域的独立调查公司。
