Abstract:
Aviation is growing rapidly, and the need for reliable and robust wireless signaling for communications, navigation, and surveillance is growing accordingly. As with all communication systems, the physical layer (PHY) forms the foundation—higher-layer operation is irrelevant if the PHY fails. In this talk, we briefly describe the growth in aviation and in related areas of wireless communications, some nascent applications and national/international programs aimed to support these applications, and then turn our attention to the PHY, where we describe some of the unique challenges of aviation networking, focusing on the air-ground and air-air channels themselves. These elements of the communication system can be rapidly time-varying, distorting, and lossy, hence quantification of channel effects is critical to enable design of effective PHY techniques to ameliorate them. We show example results from a prior and recently-completed NASA projects that illustrate some of these challenges. The talk concludes with a summary and identification of some key future work.
