scope:

The aim of the Radiocommunication Data Dictionary (RDD) is to improve the exchange of notification and coordination data between administrations and between administrations and the Radiocommunication Bureau (BR) by:

- providing a single comprehensive reference source; 

- presenting consistent, accurate and unambiguous descriptions for the data with, where appropriate, references to other ITU documentation containing additional relevant information; 

- providing administrations with a resource for their internal frequency management processes which could include such items as staff training, exchange of technical data, upgrading of computer-based systems, and conference and meeting preparation.
