Flying with WiFi Internet access what experience? Measured FAQ-plane, WiFi-IT information
Flying can also use WiFi Internet access? Don't tease me, how I even phones in no way by plane? Not the way mobile phone, how to use the WiFi Internet ... ... Aircraft flight offering WiFi Internet access service, has been a topic of concern. Especially in the flight path for a long time and can use WiFi Internet access can easily pass the time passing, also lets business travelers with their work in a timely manner. Not long ago, the well-known technology media reporter from the CNET Gogo company were invited to experience the new generation of airplane WiFi service, actual experience what are the results?

The CNET reporter aboard flights with Gogo company new 2Ku transmission technology through SpeedTest, test, downlink bandwidth up to 10.26Mbps 。 And at the use of laptops, smart phones, tablet computers and other equipment, different Internet activities, respectively, wouldn't be cotton. WiFi Internet access like this experience, has been at the leading level in the air flight. High-speed downlink speeds and even rival and home broadband.

To use WiFi Internet access on the plane, the principle is what? It's really quite simple, network signal on the plane, coming from satellites in space. In the current aviation satellite communication systems, the most common is the use of the Ku-band and Ka-band satellite communications. Among them, from 2004 began to deploy using Ku-band satellite communications technology, bandwidth, speed and cost of equipment has many advantages, such as, aviation communication has become more mainstream in the world of technology, and can also be applied on the ISS information and communication.

Currently known Ku-band satellite communications technology theoretical downlink speed of up to 70Mbps, but because of the loss in signal transmission and other factors, actual downlink speed is only between satellites and aircraft at around 30-40Mbps. Meanwhile, speed to actually experience, network speed will be the ground, differences connected to the website, cover routes within the aircraft, and the impact of different factors such as number of in-flight Internet access. Ku was ratified by our country's civil aviation Internet access technology, now quite a number of domestic flights have WiFi coverage, but mostly for its Internet intranet transmission, true Internet connection on the plane, it still takes time.
坐飞机用WiFi上网到底啥体验？实测解惑 - 飞机,WiFi - IT资讯
坐飞机还能使用WiFi上网？别逗我了，怎么我坐飞机连手机都不让开？不让开手机，还怎么使用WiFi上网……飞机飞行过程中是否提供WiFi上网服务，一直是一个备受关注的话题。尤其是在长时间的飞行路途中，能够使用WiFi上网能够帮助旅客轻松打发时间，也可以让商务乘客及时处理自己的工作。不久前，知名科技媒体《CNET》的记者受邀体验了Gogo公司新一代的飞机WiFi服务，实际的体验效果如何呢？

《CNET》的记者乘坐配备Gogo公司新一代2Ku传输技术的航班，通过SpeedTest的测试，下行带宽可以达到10.26Mbps左右。并且同时使用笔记本电脑、智能手机、平板电脑等设备，分别进行不同的上网活动，也不会感到卡顿。这样的WiFi上网体验，在飞机飞行过程中已经处于领先的水平。高速的下行速率，甚至可以和家庭宽带相媲美。

飞机上能够使用WiFi上网，其原理是什么呢？其实很简单，飞机上的网络信号，来自于太空中的卫星。在当前的航空卫星通信系统中，最常见的是利用Ku波段和Ka波段展开的卫星通讯。其中，Ku波段卫星通信技术从2004年便开始部署使用，在传输带宽、速率及设备成本等方面都具有诸多优势，已成为目前全球较为主流的一种航空通讯技术方式，并且也被应用于国际空间站的信息通信上。

目前已知的Ku波段卫星通信技术理论下行速率最高可达70Mbps，但由于在信号传输过程中损耗等多种因素影响，卫星与飞机间的实际下行速率仅在30-40Mbps左右。同时，实际上网速度体验，还会受到地面网络速度，连接网站的差异，覆盖航线内飞机数量，以及机内上网人数等不同因素的影响。Ku技术也是我国批准的民航互联网接入技术，现在国内的不少航班也有WiFi覆盖哟，不过其上网方式大多是内网传输，真正实现在飞机上连接互联网，尚需时日。
