Wireless communications with unmanned aerial vehicles: opportunities and challenges
Wireless communication systems that include unmanned aerial vehicles promise to provide cost effective wireless connectivity for devices without infrastructure coverage. Compared to terrestrial communications or those based on high altitude platforms, on demand wireless systems with low altitude UAVs are in general faster to deploy, more flexibly reconfigured, and likely to have better communication channels due to the presence of short range line of sight links. However, the utilization of highly mobile and energy constrained UAVs for wireless communications also introduces many new challenges. In this article, we provide an overview of UAV aided wireless communications, by introducing the basic networking architecture and main channel characteristics, highlighting the key design considerations as well as the new opportunities to be exploited.
