scope:

This white paper provides a broad overview of potential communication technology and spectrum usage options for uncrewed aerial systems (UAS). This paper particularly focuses on the detect and avoid (DAA) or collision avoidance (CA) use case, in line with the vehicle-to-vehicle (V2V) uncrewed aerial vehicles (UAV) use case white paper and examines the advantages and disadvantages of state-of-the-art technologies for DAA/CA use case. While specific frequency bands are discussed, along with communication requirements of the UAS, solutions for spectrum usage designs and experimentation have been reserved for white papers to emanate from future IEEE P1920 UAV standard groups. For the rest of this white paper, the terms UAS and UAV will be used interchangeably and will refer to the aerial vehicular system in totality.
