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.
The work will include a range of technical updates and innovations as well as participation in the global network SooGreen (Service-oriented optimization of Green mobile networks).
Sweden has high ambitions when it comes to the energy objectives for 2020. To mention a few of them, the total energy consumption should be reduced by 20 percent and more than 50 percent of Sweden’s energy should come from renewable sources. For Tele2 Sweden, it is the nationwide 4G network that consumes most energy, as it accounts for about 70 percent of the company’s total energy consumption.
Tele2 is currently working to streamline the energy consumption of the 4G network and secure the network sustainability for the future. Amongst other things, the company is testing a solution where the base station power amplifier is turned off when the station has no data to transmit. Other innovations will also be evaluated, for example shutting down one or more antenna ports at low load and smart measures to extend the battery life of the base stations during power outages.
Tele2 is also, as the only Swedish operator, a part of the international initiative SooGreen that has support from Vinnova and aims to create a greener telecom industry. Within the initiative, Tele2 will work together with KTH to spread knowledge on how the telecom sector can become more sustainable in the future.
