DRM Field Trials

Information on DRM field trials

Extensive tests and field trials have been conducted throughout the World using the DRM system. The results confirm that the DRM system (both the DRM30 and DRM+ variants) performs according to the specification and that it can be implemented to meet a wide range of requirements in all types of environment. The results are too extensive to adequately cover in this document; instead references are provided to reports, many of which were submitted to the prevailing ITU-R Working Party, to assist in the preparation system and planning standards. The list is not exhaustive, however further references are contained within the listed sources.
