Draft Allotment Plan for Terrestrial Digital Radio Broadcasting (DRB)

Introduction

Industry Canada announces the publication of a Draft Allotment Plan for Terrestrial Digital Radio Broadcasting for stations operating within the 1452 to 1492 MHz frequency band (L-band) using the EUREKA 147 (DAB) system.

The EUREKA 147 (DAB) system is a wide-band digital transmission technology proposed for adoption in Canada as an eventual replacement for existing AM and FM analog sound broadcasting. This system was the subject of Canada Gazette SMBR-003-95, "Adoption of a System Standard for Digital Radio Broadcasting (DRB) in Canada", which was published on August 5, 1995.

DRB Allotment Plan Strategy

The Draft Allotment Plan is based on principles developed in government/industry discussions following the world-wide allocation of the 1452 to 1492 MHz frequency band for DRB at the 1992 World Administrative Radio Conference (WARC-92). These include the following, which were taken into account to the extent possible in the development of the Draft Allotment Plan:

  • DRB should be introduced as a replacement service to AM and FM services.
  • For FM stations, the plan should accommodate DRB facilities which will provide for replacement of their existing coverage and have the potential to expand to the highest class of FM station in the community.
  • For wide-coverage AM stations, the plan should accommodate stereophonic DRB facilities equivalent to the highest Class of FM station in the community. For limited coverage AM stations, the plan should permit replacement of existing coverage, with potential to expand to the highest class FM station in the community.
  • Coverage should be based on service in more than 90% of locations, 90% of the time for mobile reception
  • Provision should be made for additional terrestrial DRB services.
  • Provision should be made for ancillary services.
  • Provision should be made for a future satellite component.
  • Systems in the fixed service should be taken into account to the extent possible.

DRB Plan — Description

The 40 MHz of available spectrum was divided into 23 DRB channels. Each DRB channel can accommodate up to five CD-quality stereophonic programs and ancillary data. Up to five existing AM and /or FM broadcasters are grouped together to share the same transmitting facility.

The Plan includes:

  • DRB service areas and groupings for existing AM and FM stations
  • frequencies for each of the DRB service areas
  • frequency re-use contours for the DRB service areas
  • identification of fixed systems impacted by DRB

As usual allotments near the border area will need to be coordinated with the United States. Industry Canada has started discussions with U.S.A. officials in this regard.
