WRC-27 AI Overlap Bands

Frequency bands addressed by more than one WRC-27 agenda item, from the CPM Report's cross-reference table. A filled dot marks an agenda item that studies the band; its colour shows the responsible ITU-R Working Party. Rows where several items meet are where coordination — and contention — concentrate.
