BBC and Arqiva secure efficient transmission with lower carbon impact
The BBC DAB network is one of the largest in the United Kingdom, covering more than 97% of the UK population. With rising operational costs and a mandate to cut carbon emissions on U.K. terrestrial platforms by 28% by 2030, the BBC and Arqiva proposed an approach focusing on “good enough” broadcast quality rather than peak performance. This strategy could potentially optimize energy consumption, reducing operational expenses and significantly shrinking the network’s carbon footprint. Traditionally, radio stations aim for maximum broadcast performance, prioritizing coverage quality without accounting for the energy cost of maintaining peak performances. The BBC and Arqiva’s approach, detailed in a paper presented at the IBC2024, flips this model by identifying a sustainable balance.
