Telemetry Spectrum Encroachment Review of Related WRC-27 Agenda and Domestic Threats

Abstract

A review of international and domestic spectrum issues that present challenges for the future use of radio frequency telemetry after the 2023 World Radiocommunications Conference (WRC-23). Several agenda items addressed there have a potential for telemetry spectrum encroachment and are presented in this paper. Agenda topics of telemetry interest in future World Radiocommunications Conferences (WRCs), in particular several agenda items that will be considered at the 2027 World Radiocommunications Conference (WRC-27), are a particular focus. International telemetry vendors, suppliers, and users need to be aware of, and potentially engage with, their national administrations on these items to protect and preserve spectrum for the future of aeronautical mobile telemetry.
