RALIs to coordinate frequency

Radiocommunications assignment and licensing instructions (RALIs) ensure everyone uses spectrum effectively.


RALIs contain the rules to licence and coordinate frequency between services in a band. They help people avoid interference when they assign frequency. We develop them for:

  • accredited persons who assign or coordinate frequency
  • those who plan systems or sell equipment

Business operating procedures also guide accredited persons in their work.
