Categorization of the W(A)RC Recommendations in force

The table below lists all the World (Administrative) Radio(communication) Conference (W(A)RC) Recommendations in force after WRC-19. The elements of each Recommendation relating to the ITU Radiocommunication Sector (ITU-R) are contained in the column titled “recommends”. Links to the relevant ITU-R Study Group (SG) documents describing the assignment of the Recommendation to sub-groups of the SG (i.e. Document 1 of each SG) is provided where applicable and when available. See Document "Categorization of the W(A)RC Recommendations in force".
