Recently, the "free WiFi all over the world" topics on the Web attracted the interest of netizens, many netizens have been discussing such possibilities of programme implementation and, of course, there are many users passing trough the current charges for domestic telecommunications carrier dad network speed and price.
It is understood that this is what we call the "Outernet" project affiliated with United States media development investment fund corporation, the company plans by June 2015 to launch 150 mini-satellites into low-Earth orbit, through which the satellite, any electronic terminal can connect to wireless networks. This news came out, the domestic users have praised. Still do not know whether the implementation of the project. Don't know if domestic users can also join, but netizens have so much looking forward to it.
It is easy to understand, since entering the mobile Internet era, we have been accustomed to always have access to the Web to get information of life, for many people, the day without Internet is a kind of torment. For now, the WiFi network is the most convenient and most affordable way we access the Internet, operators networks not only speed makes it difficult to guarantee, and charges are relatively expensive, giving free WiFi into a multitude of people on the other side of the TT. This can also be confirmed in our lives, many businesses have free WiFi as a means of attracting consumers.
So, make plans for free WiFi all over the world can really practice? If we can achieve, and what are the problems?
Industry experts say that, in the long term, technical feasibility is not a problem, with the present technology, basic can be done, and advancement of technology, it will become easier to achieve, and communications will continue to get better results.
Although technically has been achieved, but the idea of free WiFi all over the world still has many problems.
First, health problems. At present, although experts say WiFi network basically harmless to the human body, but there are still a lot of people are still not comfortable, and every now and then we also have heard about WiFi is bad news. It is understood that if this WiFi network using mobile terminal directly connected satellite signal, it will need a larger mobile phone power, which may be harmful to the human body. But this problem is not cannot be resolved, experts say ground base station relays signals can be used to reduce impacts.
Followed by network security problems. Netizens worry if everyone Internet access through WiFi networks, hackers will certainly keep an eye on network signal available on satellite, if the satellite was occupied by hackers, that is not our data will be controlled by hackers? But there are also netizens who expressed, network security is always present, there is a risk of using any Internet products, but not all with for so many years is not much to lose? It's just a matter of probability, not choking. Moreover, if the wholesale use of the free WiFi network, there will definitely be extremely strict protective measures, and now our broadband Internet access will not be too different.
Third, a lot of people are most concerned about is the issue of personal privacy. Before the era of mobile Internet and fixed-line times are different, if a WiFi network access, adoption of smartphones , and Tablet PCs and other mobile devices, we precise personal location information and other sensitive data exposed. Individuals or organizations with ulterior motives will be a real-time understanding of our most private data, not just privacy issues, even thrown security issues directly.
In addition, there are quite a few people might worry that, if we had to rely on WiFi Internet connection at all times, if hijacked by foreign carriers do, we would have lost control over the network.
Netizen, many worry it is receiving, from which we can easily find, free WiFi coverage of the global idea is very beautiful, has catered to many expectations for high-speed, free Internet, and certainly reflects dissatisfaction with netizens on the three major domestic carriers network, but in real implementation will still face a lot of problems, eventually may be a beautiful soap bubble. But, then I thought again about these problems, what are you? Don't tell me now, this project has also ghost, even if it comes, will not completely kill the other Internet access methods. In the future, perhaps 4G with complementary WiFi is in the form of a more reasonable and effective way to access Internet.
免费wifi覆盖全球，美丽的肥皂泡 - 免费wifi覆盖全球,Outernet,wifi上网 - IT资讯免费wifi覆盖全球，美丽的肥皂泡
近日，“免费wifi覆盖全球”的话题在网络上引起了网友的极大兴趣，许多网友都在讨论这种方案实施的可能性，当然，也有不少网友顺带吐槽了当前国内电信运营商的坑爹网络速度与资费价格。
据了解，这个叫做“Outernet”的项目隶属于美国的媒体发展投资基金公司，该公司计划在2015年6月前向近地轨道发射150颗迷你卫星，通过这些卫星，任何电子终端都能连接上无线网。此消息一出，国内网友纷纷点赞。虽然还不知道该项目能否最终实施。也不知道国内用户能否加入，但网友们依然抱有很大想期待。
不难理解，自从进入移动互联网时代，我们都已习惯了随时都能接入网络获取信息的生活状态，对很多人来说，没有网络的日子简直是一种煎熬。就目前而言，wifi网络是我们接入互联网最方便最实惠的一种方式，运营商提供的网络不但网速难以保证，而且资费相对较贵，这就让免费wifi成了无数人追捧的香饽饽。从我们的生活中这一点也可以得到印证，很多商家都把免费wifi作为一种吸引消费者的手段。
那么，让免费wifi覆盖全球的计划真的可以实现吗？如果能实现，又存在哪些问题呢？
有业内相关专家表示，从长远来看，技术上的可行性不是问题，以目前的技术来看，基本能够做得到，而且技术是不断进步的，实现起来将越来越容易，通讯效果也将越来越好。
虽然技术上已经实现，但是免费wifi覆盖全球的设想仍然存在不少问题。
首先是健康问题。目前，虽然有专家表示wifi网络对人体基本无害，但仍有不少人对此仍不放心，并且我们也会时不时的听到有关wifi有害的新闻报道。据了解，如果这种wifi网络采用移动终端直接连接卫星信号的方式，那将需要较大的手机功率，这样有可能对人体有害。但这个问题并非无法解决，有专家表示可以采用地面基站中转信号的方式减小影响。
其次是网络安全问题。有网友担心，如果大家都通过wifi网络上网，那黑客肯定会盯上提供网络信号的卫星，如果卫星被黑客占领，那我们的各种数据岂不是就会被黑客控制了？不过也有网友对此表示，网络安全问题是始终存在的，使用任何互联网产品都存在一定的危险性，但这么多年来不也都没有太大的损失吗？这只是个概率问题，不能因噎废食。况且，如果这种免费wifi网络被大规模的采用了，肯定会有极其严格的防护措施，与我们现在的宽带上网差别不会太大。
第三，很多人最关心的就是个人隐私问题了。移动互联网时代与以前的固网时代不同，如果全面经过wifi网络接入，通过智能手机、平板电脑等移动设备，我们精确的个人位置信息等敏感数据将暴露无遗。别有用心的个人或者组织将实时掌握我们的最隐私数据，到时候可就不仅仅是隐私问题了，甚至会引发直接的安全问题。
此外，也有不少人可能会担心，如果大家到时候都依赖这种wifi网络上网了，万一被国外运营公司劫持怎么办，我们岂不是失去了对网络的控制权。
网友的很多担心不无道理，从中我们也不难发现，免费wifi覆盖全球的设想虽然很美丽，迎合了很多人对高速、免费网络的期待，当然也反映了国内网民对三大运营商网络的不满，但是在真正实施起来的时候仍将会面临很多的问题，最终或许只是个美丽的肥皂泡罢了。不过，转念再一想，这些问题又算什么呢？别说现在这个项目还没谱，就算真的来了，也不会完全杀死其他上网方式。在未来，或许4G与wifi互补的形式才是一种更为合理有效的上网方式。
