The 1st Inter-regional Information Session (IRIS) on WRC-27 Preparation is a face-to-face event organized in accordance with Resolution 72 (Rev.WRC-19) with the possibility of remote participation (see Programme).
Using information from the ITU-R responsible groups on the ongoing preparatory studies for WRC‑27 (see at itu.int/go/rcpm-wrc-27-studies), as well as on up-to-date information regarding the Bureau and regional preparations for CPM27-2, RA-27 and WRC-27, round tables provide all the stakeholders with the opportunity to exchange views and gain a deeper insight on the most challenging WRC‑27 agenda items and issues, as well as of the draft preliminary common views and/or positions of the concerned entities.
