How AI Can Reduce Energy Consumption and Drive Sustainability in FM Radio Broadcasting

With energy costs soaring across the globe, reducing energy consumption is increasingly a top priority among radio broadcasters, to reduce operating costs as well as to meet the world’s growing need to implement greener solutions. In the broadcasting chain, the transmitter represents the most impactful device from an energy-usage perspective, as it continuously delivers a fixed output power to the antenna. In the FM chain, transmitters go from a few watts to dozens of kilowatts depending on the coverage area, landscape and radio listeners’ profile. To support broadcasters in meeting their sustainability goals and economic challenges, a technique called SmartFM is described in this paper that enables up to 40% lower energy consumption.
