Radcomms interference stats: 2011–12

To give stakeholders and other citizens better insights into our investigations work, we present this statistical breakdown of the interference investigations work we have recently done and are currently doing. Where investigations are ongoing, or have not been published, the ACMA is generally unable to give detail of the entities and issues involved for individual matters or otherwise make comment. The following tables are prepared from information collected for each interference investigation activity according to standardised terminology and events.


Total number of ACMA compliance activities: 494
Note: Each complaint has only one type of affected service.
*Such as devices authorised under the LIPD and Maritime Ship Station class licences or non-assigned apparatus licences (other than amateur licences).
+'General' radiocommunications services are those that fall outside the categories identified above. They include apparatus-licensed 'two-way' communications services.

++The repair cost outweighs the cost of replacing the receiving equipment.
Note: QRM is a Q code for man-made interference.
