o3bnetworks,是最近一个很火的概念，
号称上网费下降95%！Google卫星上网 30亿人受益。
我没事去o3bnetworks里面看看，
刚刚去o3bnetworks网站里面看看，网站还是比较简单
Geosynchronous (GEO) satellites 36,000km away from Earth. As a result, round-trip data transmission times significantly exceed 500 milliseconds. O3b’s medium earth orbit (MEO) satellites are far closer – approximately 8,000km away from Earth. As a result, round-trip data transmission times are reduced to approximately 100 milliseconds
卫星是36，000km，
O3B是8，000km，所以100毫秒一个round-trip
six satellites are sufficient to achieve constant coverage.
6颗卫星就可以达到目标覆盖
Supports newer 3G protocols and beyond (EVDO Rev. A/LTE/HSDPA)
3G, WiMAX and fixed-line networks
支持3G
个人感觉是结合3g技术和低空卫星技术的一个方案
上面说的VSAT跟这个还是有区别的，是VSAT的下一代。
他的宣传照片，思路有点意思
