Abstract
Civilian application of Unmanned Aerial Vehicles (UAVs) are becoming more and more widespread. An important question is how ultra-reliable communication to and from the drone will be organised. At the moment complex and difficult to deploy point-to-point proprietary wireless links are often used. To enable ubiquitous usage of UAVs it is necessary to have a simple, reliable and widely available data link, such as IEEE 802.11. In this work we examine if infrastructure to control UAVs could be built from IEEE 802.11 access points already deployed for other applications. Our conclusions are based on a combination of measurements and simulations. The analysis presented assumes, but is not limited to, a representative UAV mission that involved streaming video to the ground. The proposed framework then significantly improves reliability by allowing the UAV to broadcast to multiple ground receivers and solves the limited acknowledgment available to the aerial node by applying FEC at the application layer.
