世界上一半以上的人口在上网方面面临障碍。国际电联最近的一项研究估计，26亿人负担不起连接费用，38亿人无法获得连接。最近提出的提供低成本连接的建议包括在平流层部署无人机和长效气球。我们提出了一个更经济的替代方案，我们称之为Wi-Fly，它利用现有的商用飞机为偏远地区提供互联网连接。在Wi-Fly中，我们实现了商用飞机上的轻量级Wi-Fi设备与地面站之间的通信，从而在没有低成本互联网连接的地区实现了连接。Wi-Fly利用飞机上现有的ADS-B信号作为控制信道，确保飞机与地面之间存在强大的链路，并且站点智能唤醒并关联到适当的AP。为了我们的实验，我们定制了两架飞机来进行测量。通过试飞和模拟的实证实验，我们表明Wi-Fly及其扩展有可能以比现有替代品低得多的成本为世界上最偏远的地区提供连接。
More than half of the world's population face barriers in accessing the Internet. A recent ITU study estimates that 2.6 billion people cannot afford connectivity and that 3.8 billion do not have access. Recent proposals for providing low-cost connectivity include fielding of drones and long-lasting balloons in the stratosphere. We propose a more economical alternative, which we refer to as Wi-Fly, that leverages existing commercial planes to provide Internet connectivity to remote regions. In Wi-Fly we enable communication between a lightweight Wi-Fi device on commercial planes and ground stations, resulting in connectivity in regions that do not otherwise have low-cost Internet connectivity. Wi-Fly leverages existing ADS-B signals from planes as a control channel to ensure that there is a strong link from the plane to the ground, and that the stations intelligently wake up and associate to the appropriate AP. For our experimentation, we have customized two airplanes to conduct measurements. Through empirical experiments with test flights and simulations, we show that Wi-Fly and its extensions have the potential to provide connectivity to the most remote regions of the world at a significantly lower cost than existing alternatives.
