Challenges of World Radio Conference studies: 10 GHz spectrum

The outcome of the World Radio Conference 2019 (WRC-19) has now been disseminated, changes to regulations and technical licence conditions are being implemented and spectrum awarded. Attention is now turning to the agenda items identified for the next World Radio Conference, scheduled for 2023 (WRC-23). Preparatory work will be starting within ITU-R, as well as regional and national bodies, to address the necessary studies needed to inform future spectrum decisions.

Simple minimum coupling (worst case) sharing studies are usually the first step in assessing any changes to frequency allocations. Then, depending on the outcome, these may be followed by detailed discussions and analysis involving other considerations such as density and geographic location of incumbents, coordination requirements and remedies for incumbents.

This Insight highlights the challenges faced when considering one of the agenda items, as an example, that will be addressed over the forthcoming study period, namely the potential for 10 – 10.5 GHz to be identified as an IMT band.
