This chapter examines the enabling role of cognitive radio technologies for unmanned aircraft systems to access more spectrum needed for flight operations. Analysis of stakeholders sets the requirements for cognitive radios. With these requirements, the paper describes the different architecture choices available to the UAS cognitive radio designer. These include the communication architecture, the spectrum awareness techniques for assessing what spectrum is available, and the spectrum access techniques for deciding which available spectrum to use. Cognitive radios provide a number of benefits over traditional radios: they increase spectrum management flexibility and automatically resolve conflicting allocations. This promotes more widespread spectrum sharing, increasing the spectrum available. It provides mechanisms to automatically make fine-grained allocations, such as spectrum reserved for specific phases of flight, which increases unmanned aircraft flight safety. It enables new business models of spectrum management that can encourage better allocation of spectrum resources. Information from this chapter is relevant for the development of future unmanned aircraft systems rules and standards.
