A large amount of energy is needed to power the mobile network infrastructure. This makes energy efficiency an
environmental as well as a business priority. There are several initiatives to increase energy efficiency in mobile
networks by GSMA, EUREKA (Eureka/SooGREEN)
and other organisations. In Sweden, Tele2 is launching an extensive project to make its 4G network even more
energy efficient to contribute to the highly set climate goals for 2020 that Sweden and the UN have established (Tele2 Press Release).
Mobile networks are experiencing an exponential growth of traffic volumes, associated with the
emergence of new services. Telecom manufacturers and operators should design mobile networks that are able
to absorb this drastic increase of traffic while mastering their energy consumption.
Maven next-generation digital DAS is designed to support the expansion of existing mobile networks including
future technologies such as virtual RAN and 5G. At the same time, Maven digital DAS’ power consumption is
reduced to less than half the power consumption of current solutions, reducing operating costs, environmental
footprint and eliminating cooling fans. For a medium size DAS system this means an annual cost saving of
approximately 20kEUR. The annual energy saving is equivalent to the combustion of 70 tons of coal generating
124 tons of CO2 emissions.
