The green credentials of DAB+

A new report from Germany has taken a look at the cost of setting up and running DAB+ and FM networks across Bavaria, from the number of transmitter sites required through to  power requirements on an ongoing basis.

It was put together by Bayern Digital Radio (BDR) and a translated version can be downloaded from here.

BDR found that, based on current networks and technologies, power savings of up to 80% are possible (per station or programme) by using DAB+ instead of FM across Bavaria.


Additional detail on the efficiencies of DAB can be found in this report that was presented earlier in the year. In particular:

  • DAB+ transmitter investment costs are eleven times lower compared to FM
  • DAB+ energy savings are 41 times greater compared to FM
  • DAB+ opex costs between 5.7 and 12.8 less than FM
  • DAB+ heat dissipation is 18 times lower compared to FM
  • Space savings on transmission site – 18 times less occupied floor space with DAB+ compared to FM
  • The cost of DAB+ transmitter tower and hall space is 18 times lower compared to FM
  • Reduced service & maintenance cost – DAB+ maintenance is half that of FM
