IEEE 1920.1-2022

IEEE Std 1920.1 defines air-to-air communications over self-organized aerial ad hoc networks and describes the reference architecture for aerial networks, where aircraft can form a network to share information with one another with or without any supporting infrastructure, such as satellite or cellular communications. This standard is intended for RLOS and BRLOS small UASs used for civil and commercial applications. The architecture can also be extended to include additional platforms, making it a useful guide for other aircraft systems. The communications and networking standards are independent of the type of network (wireless, cellular, or other). The main objective of the IEEE Std 1920.1 data model is to define and format data consistently in a common, secure data structure that can be leveraged across the industry. This can help improve the integrity, safety, and security of the data regardless of the types of use cases, communication technologies, or diversity of the vehicles utilized. IEEE Std 1920.1 does not specify procedures or protocols that define the means to access radio-frequency spectrum and manage its use (i.e., an “air interface”). IEEE Std 1920.1 does not specify the size, maximum take-off weight (MTOW), modes of propulsion, and other characteristics of the UAS. It is expected that most UASs with less than 250 kg MTOW can use the protocols defined in IEEE Std 1920.1. An MTOW above 250 kg would put the UAS in the scope of certification requirements that impose requirements beyond those applicable to aircraft operating communications services within the scope of IEEE Std 1920.1.
