The advantage of mobile radio stations with area frequencies is that they provide particularly large areas with stable and reliable mobile radio coverage. By bundling the active technology of different frequency ranges and several radio cells in one unit, they now require between 32 and 40 percent less energy, according to trials on the Vodafone network. Following successful tests in the North Rhine-Westphalia (NRW) region, the telecommunications group is now successively activating the technology in the live network together with its technology partner Ericsson.

The new energy-saving radio from Ericsson has been intensively tested in the live network in Wachtendonk in the Lower Rhine region over the past few weeks. The positive test results demonstrate an energy-saving potential of up to 40 percent per 5G base station and are the reason for today’s large-scale rollout. The new technology will be installed and automatically activated in NRW, Rhineland-Palatinate, Hesse, Saarland and Baden-Württemberg during routine maintenance and modernization work.

Test results on the Vodafone network show that energy requirements can be reduced by more than 2,500 kilowatt hours (kWh) per mobile phone site per year by bundling the active technology. This is roughly equivalent to the annual energy requirement of a two-person household per mobile phone station. If the technology is activated on a large scale in the network, significantly more than 30 million kilowatt hours of electricity can be saved each year. At the same time, stable and reliable network coverage will also be strengthened in rural regions.

Vodafone Germany CEO Philippe Rogge, says: “For the first time, we are bundling the active antenna technology of different area frequencies in mobile communications. This is good for smartphone users in rural areas and good for our planet. Because with the new technology, we are bringing fast and reliable 5G networks even better to people in rural areas and deep into buildings. At the same time, we are reducing the energy requirements of our mobile phone antennas. We expect to be able to save more than 30 million kilowatt hours of electricity per year with large-scale activation in our network.”

Daniel Leimbach, Head of Western Europe at Ericsson, says: “Energy consumption reduced by up to 40 percent, weight reduced by 60 percent – around a year ago, we celebrated a world premiere at the launch of the Radio 6646 at the Eurolab in Aachen. At the Imagine Live Innovation Day in the research and development center, our experts presented the innovative 5G technology for the first time. We are all the more pleased that Vodafone is convinced of its performance and energy efficiency and is installing the technology in the area. Because only innovations that are scalable, economical and powerful at the same time deliver the full benefits for mobile customers and sustainability.

The technology in Ericsson’s new radio:

Ericsson’s new remote radio combines the different 5G area frequencies 900, 800 and 700 MHz as well as the components of several radio cells into one compact system in a more sustainable way. By bundling three frequencies and several radio cells, the transmission technology consumes significantly less energy for each individual frequency range at full power. In addition, the new radio is 60 percent lighter and therefore requires less energy and material in the manufacturing process.

On the way to CO2 neutrality:

The new antenna product is another building block on Vodafone’s path to becoming more sustainable step by step. The Düsseldorf-based company has set itself specific targets to be CO2-neutral by 2025. The network is the biggest and most important lever here. Vodafone Germany has therefore been sourcing 100 percent of its electricity from renewable sources since 2020. It is also constantly testing new technologies and solutions to make the German mobile network more sustainable and conserve resources. For example, the dynamic energy-saving mode in the mobile network has already been ensuring an intelligent adjustment between actual energy demand and consumption around the clock for over a year.
