Energy efficiency is not only an important goal for Telekom in planning new networks, it is also important when optimizing existing ones. Better performance and less energy consumption go hand in hand.
The largest system technology swap in the history of Deutsche Telekom's mobile business began on September 4, 2011: the replacement of Alcatel-Lucent's outdated 2G/GSM technology with state-of-the-art Huawei technology. The plan is to replace the technology at a total of some 12,000 mobile communications sites and replace more than half of the outdated 2G/GSM systems. The number of controller sites for base stations will be reduced from 256 to 13 over the course of the swap.
By modernizing the technology we are laying the foundation for a future-proof technology platform which is not only suitable for LTE expansion, but will also ensure that the same hardware can be used for all mobile communication generations (2G , 3G and 4G/LTE) in the long term. The aim is to avoid future investments and reduce operating costs. In addition, the 2G network technology will be IP-enabled, thus meeting the future requirements of the fixed network (All-IP ).
We were able to successfully complete the UltraSite Swap upgrade project in September 2011. We replaced the outdated 1st generation 3G technology at around 3,100 base stations with the latest generation of efficient system technology. In addition to improving data transmission, which made it possible to activate HSPA+ with a bandwidth of 42 Mbit/s throughout Germany, we were able to save around 8,000 kWh of power each year per base station. The project resulted in overall savings of 24.8 GWh/year.
The high-speed VDSL network is based on fiber optic cables. Individual network components are bundled in cabinets, recognizable as the gray boxes found throughout the city. In order to further increase the energy efficiency of the technology contained in the cabinets and to minimize performance loss, we initiated the Best Power project in 2011.
The focal point of the pilot project is selecting the most effective network devices and increasing the energy efficiency of our system technology. We plan to reduce our CO2 emissions as well as our operating costs with the energy reduction the project is expected to generate. Official results will not be available until a field test has been conducted in late 2013, since a subproject of Best Power is being conducted in connection with the DESI project.
In 2011 we were able to shut down unnecessary technical systems with a wattage of overall 4,286 kW due to measures implemented by the Power Off task force. The energy savings realized as a result are the equivalent of 16,564 metric tons of CO2 per year.Find out more
The Power Off task force at Telekom Deutschland analyzes which residual modules can be removed from the network with a reasonable effort and organizes the systematic dismantling of outdated systems.
The prompt dismantling of technical systems that are no longer needed helps to cut energy consumption considerably. By dismantling these systems in 2011, Telekom can save around 37 GWh in electrical energy consumption as well as other costs amounting to EUR 8 million for electricity, cooling and uninterrupted power supply each year. In addition, the measures freed up one-time investment resources in areas such as cooling and uninterrupted power supply totaling at around EUR 8.4 million. These will be used to accelerate the installation of new, more energy-efficient networks.
The Montenegrin subsidiary Crnogorski Telekom began a program to upgrade its entire mobile communications infrastructure in mid-2011. A pilot project in the city of Bar, in which all services were migrated over to a single platform, yielded improvements to the network quality.
