Free WiFi all over the world， do you dare？ ，

Free WiFi all over the world, do you dare?
Global-free WiFi, WiFi, Wi-Fi-IT information Free WiFi all over the world, do you dare?

Experts say the technical fine Netizen are worried about their privacy leaks

Really going that day, our anywhere, anytime, just take out your cell phone can connect to free WiFi? Numerous "bowing" dream can become a reality. United States agencies on proposed to create the "OUTERNET" (extranet) project , by June 2015 to launch 150 mini-satellites into low-Earth orbit, these satellites, the use of any electronic terminal can be connected to the wireless network.

The Agency said projects or offering free services. The news came out, many netizens cheered: without high cost 4G to sell the House. However, at the same time, there is concern that using the free WiFi security or not?

Sweet dreams:

Free WiFi all over the world can only download not upload

According to United States media reported on February 6, United States authority to every corner of the world is covered to a wireless network this dream into a reality. Reports said this was called the "OUTERNET" (extranet) project until June 2015 to launch 150 mini-satellites into low-Earth orbit, deliver a Wi-Fi signal at the satellite earth stations-oriented, covering all over the world, the use of any electronic terminal can be connected to the wireless network. In this regard, communications experts say, regardless of cost and technical feasibility, after global free WiFi to achieve personal information safety issues worth paying attention to.

In its website, extranet claimed that its primary purpose is to reduce the global information divide, is the view of the current high cost of Internet access and set up many places do not have Internet access. Judging from its current planning, starting from December 2013 first round of technical assessment of the project, is now in long distance WiFi multicast satellite model development and testing phases. After the project is completed, formal mainly dominated by one-way transmission similar to TV-through this channel, transmission to the user information, education courses, mobile, movies, music, and occasionally in the response under such circumstances act as channels of communication (bi-directional) and so on.

Experts say:

Technology is not an issue for information protection concerns

This news came out, and immediately attracted attention, domestic professionals engaged in mobile communications and information services in an interview with reporters, said in the long run, technically and financially feasible are not a problem, the key is how personal information should be protected.

Mobile communications expert Li, told reporters: "it is technically feasible, this project is a satellite in the sky covering an area, these areas tend to be those where network coverage is not so good, followed by ground base station users can go online; but I personally feel the investment is relatively large, major satellite investments will be very large, so that bandwidth is not too high. "Chinasoft International Limited and information technology development engineer in Beijing Liu Jiangbo had expressed the same concern, he said," even if you temporarily can not to consider this item at the technical level achieved, creating such a huge amount of funds for the project who will provide? Select which site receives, provides network information partner sites? These issues are more difficult to deal with. ”

As regards the impact on people, Lee said: "if I use user terminal directly connected satellite, mobile power requirements will be relatively large, mobile phone radiation influence on people, so after a way to signal relay station, the effect will be relatively smaller. ”

In addition, global WiFi also involve privacy problems, Liu Jiangbo said: "once this wireless network, then it will be hacked preferred, this network matured, if hacking, so the impact is unthinkable. "Mr Lee expressed his frustration," not like we used to use cable broadband, our location, habits are more difficult to obtain, we now use WiFi, including wireless network at home, as long as we connected with a mobile terminal and open the application, our information is technically very difficult to avoid being getting ". "And now the Internet through mobile devices is where users are accustomed to, WiFi is a universal trend. Domestically, 4G and WiFi seamlessly is a trend. ”

User opinions:

Temptation it was difficult to arrive was worried

The hotly debated plans to attract users, it was looking forward to, concern was raised.

A Netizen named "buddies steal music" says, "is still very looking forward to it. As to steal personal information, stealing stolen chanting, the little people, not much important information. "Friend" white hair purple-British "says," I'm curious, if we are really to achieve coverage, some users won't worry about security issues without it? It's like someone gave you a loaf of bread, you going to wonder whether toxic stiff in manner. ”

A Netizen named "Yuki ink green," says, "very fishy. I heard someone else's WiFi stealing mobile phone information. If we use the United States of WiFi, if our information was collected by Americans anymore? "Friends" Jianhua, "saying," If a hacker invade a satellite, then he can directly connect millions of people's privacy, including location information is collected. One such invention is to make the world into a panic? I personally think this invention is a conspiracy. "

A Netizen named "jinanshu" from the perspective of Internet technology believes that this is the wave of the future, after all the Internet is to really go to the Center. Besides the hundreds of millions spent, scale and technology of the day clearly has reached a very high level, certainly not now, hundreds of satellites. This kind of thing in the future depends on the imagination, there is no imagination there is no development, or should we hold a positive attitude to look at.

免费wifi覆盖全球，你敢用吗？

专家称技术层面没问题网友担心隐私外泄

真的会有那么一天，我们不管身处何时何地，只要拿出手机就能连上免费WiFi？无数“低头族”的梦想或许能够变为现实。美国有机构就提出，将打造“OUTERNET”（外联网）项目，在2015年6月前向近地轨道发射150颗迷你卫星，通过这些卫星，使用任何电子终端都能连接上无线网。

该机构称，项目或将提供免费服务。消息一出，许多网友欢呼：这下不用为了超高4G费用卖房子了。然而，与此同时，又有人担心，使用这种免费WiFi到底安全与否？

美妙梦想：

免费WiFi遍布全球只能下载不能上传

据美国媒体2月6日报道，美国一家机构准备将全世界每个角落都覆盖无线网这一美梦变成现实。报道称，这一被称作“OUTERNET”（外联网）的项目将在2015年6月前向近地轨道发射150颗迷你卫星，这些卫星面向地球地面站持续释放无线网络信号，覆盖世界各地，使用任何电子终端都能连接上无线网。对此，通信专家表示，无论成本和技术上可行与否，全球免费WiFi实现后个人信息安全问题值得关注。

在其官网上，外联网宣称其主要目的是减少全球信息鸿沟，是针对目前上网费用高和许多地方没有上网条件而设。从其目前规划来看，项目从2013年12月开始第一轮技术评估，现在正处于卫星模型发展和长距离WiFi多点传送测试阶段。项目完成后，形式上主要以类似于电视式的单向传输为主，通过这一渠道，向用户传输新闻、教育课程、手机应用、电影、音乐，偶尔在救灾等情形下充当通信渠道（此时为双向）等等。

专家说法：

技术实现不是问题信息保护值得关注

此消息一出，立即引来人们关注，国内从事移动通讯和信息服务的专业人士在接受记者采访时，表示从长远来看，技术上和资金上的可行性都不是问题，关键是个人信息安全应该如何保障。

移动通讯专家李先生对记者表示：“技术上是可行的，这一项目是天上的卫星覆盖某一地区，这些地区一般是那些网络覆盖不太好的地方，之后通过地面基站用户可以上网；但我个人感觉这里的投资会比较大，主要是卫星投资会很大，因此带宽不会太高。”北京中软国际信息技术有限公司开发工程师刘江波也表达了同样的疑虑，他说，“就算暂时不考虑这项目能否在技术层面实现，打造这么庞大的工程所需的资金由谁来提供？选择哪家网站作为接收、放送网络信息的合作网站？这些问题都是比较难处理的。”

至于对人的影响，李先生说：“要是采用用户终端直接连接卫星的方式，对手机的功率要求会比较大，这样手机辐射对人的影响肯定大，因此采用经过地面站进行信号中转的方式，影响会相对小些。”

此外，全球WiFi还涉及个人隐私问题，刘江波说：“一旦这个无线网络实现了，那么它将成为黑客入侵的首选地，这个网络成熟后如果被黑客入侵，那么它的影响是不可想象的。”但是李先生表达了他的无奈，“不像以前我们用有线宽带，我们的位置信息、使用习惯都比较难获取，现在我们用WiFi，包括家里的无线网络，只要我们用移动终端连接并打开应用，我们的信息在技术上很难避免被获取”。“而现在通过移动终端上网已是用户习惯，WiFi全面普及是一种趋势。对国内来说，4G和WiFi的无缝对接是一种趋势。”

网友意见纷纭：

有人难抵诱惑有人忧心忡忡

这一计划引来网友热议，有人表示期待，有人表示担忧。

网友“鬼鬼偷着乐”说，“还是很期待的。至于什么窃取个人信息，窃就窃呗，小老百姓一个，没啥重要信息。”网友“白发紫英”说，“我很好奇，假如真的实现覆盖，某些网友会不会因为担心安全问题而不用？这就像别人给你一个面包，你硬生生要去怀疑是否有毒一样。”

网友“纪墨青”说，“很可疑。我听过使用别人的WiFi可以盗窃手机里的信息。那如果我们用美国的WiFi，是不是我们的信息就会被美国人收集去了呢？”网友“Jianhua”说，“如果一名黑客入侵一颗卫星，那不就可以直接把无数人的隐私，包括位置信息都收集到手里了。搞一个这样的发明是为了让世界陷入恐慌吗？这个发明我个人认为就是一场阴谋”。

网友“jinanshu”则从互联网技术角度分析认为，这是未来的趋势，互联网终归要真正实现去中心化。再说如果真的上亿人用了，那时候的规模和技术显然已经发展到相当高的水平了，肯定不是现在几百个卫星了。这种未来的事情要靠想象力，没有想象力就没有发展，所以还是应该抱着积极的心态去看待。
