RALIs to coordinate frequencies

Radiocommunications assignment and licensing instructions (RALIs) ensure the efficient use of spectrum.

RALIs contain rules to coordinate and licence frequencies between services to avoid interference. RALIs are developed to assist:

  • accredited persons who assign or coordinate frequencies for spectrum users,
  • equipment manufactures and
  • those who plan systems or sell equipment

The document below outlines our program of work to update our suite of frequency assignment and coordination rules.
