Digital radio planning principles

The Digital Radio Planning Committee for regional Australia, chaired by the ACMA, works with industry to plan digital radio in regional Australia. After 12 months of extensive feasibility studies and research, the technical sub-committee (TSC) of the Digital Radio Planning Committee presented a comprehensive technical report, along with the results of the feasibility studies undertaken by the ACMA and Commercial Radio Australia (CRA) to the committee.

The technical report contained recommendations on high-level planning principles for the allotment of digital radio frequency blocks for the rollout of regional digital radio. The ACMA has now adopted these planning principles and will take these principles into account when preparing indicative regional allotment plans, which will, in turn, inform the future preparation of digital radio channel plans (DRCPs).

Read the planning principles.

Engineering and other studies underpin the allotment planning for the expansion of digital radio into regional Australia. Studies are conducted by the ACMA and industry engineers. The studies reveal the complexity of spectrum planning, and are used by the ACMA to inform its planning decisions.

The following table contains:

  • a copy of the report prepared by the technical sub-committee outlining the technical aspects of the planning of DAB+ for regional Australia
  • prediction and allotment studies undertaken by the ACMA relating to the planning of digital radio services in regional areas of Australia. (Reports will be published progressively in the Table below as detailed planning is undertaken in the relevant areas as required.)
  • national frequency block allotments for digital radio planning in regional Australia.

Indicative regional allotment plans

The ACMA will prepare indicative regional allotment plans for digital radio frequency blocks. These allotment plans will seek to provide indicative spectrum allotments for possible future digital radio services across broad regions of Australia.

The ACMA will publish the indicative regional allotment plans when they have been prepared.

Digital radio channel plans

The digital radio channel plans (DRCPs) allot frequency blocks in relation to designated Broadcasting Services Act 1992 (BSA) radio areas for use by digital radio multiplex transmitter (DRMT) licensees. The DRCPs also determine the number and types of DRMT licences to be issued for designated BSA radio areas and technical specifications of multiplex transmitters operated under DRMT licences.

Before varying or making a DRCP, the ACMA publishes consultation papers and invites comments from stakeholders and members of the general public.

Details of consultations on draft DRCPs that have closed are available on the closed draft digital radio channel plans page.

Once a draft DRCP has been finalised, it is published on the final digital radio channel plans page.
