This report is based on two independently developed methodologies in the relevant annexes. These methodologies, even though based on different approaches, provide comparable estimated spectrum requirements. The methodologies estimating the total spectrum requirements in this report addressed terrestrial and satellite requirements in a separate manner. Deployment of unmanned aircraft systems (UAS) will require access to both terrestrial and satellite spectrum.
