Most of the CO2-emmissions are created during the lifetime of network equipment. Production and disposal are also important to note, but in total with less impact on the environment. In the beginning of mobile era, power consumption and environment protection was not really a key issue. Nowadays most companies and legal entities have come to the conclusion that environmental concerns are indeed important. The telecommunication industry is putting a lot of effort to that subject. Important to note is that this can be only achieved if environmental protection meets a positive business case. If that would not be the case, these initiatives would fail. A GSM base station site formally consumed a lot of energy. The latest Nokia Siemens Networks technology allows a reduction of power consumption by more that the half to 800W. New technologies like WCDMA and LTE will consume even less power – 430W. This allows the operation using renewable and alternative engergy forms like solar power and wind in regions with insufficient and unstable power supply .
The new Nokia Siemens Networks Flexi BTS Family consumes less power and leaves a smaller footprint. Since it is physically smaller, it can be integrated in existing structures and leads to more deployment opportunities. Its light weight of around 23 kilograms and its size (like a carry on luggage) creates 80% less logistic costs. It can also be recycled to a degree of 95%. Smaller devices also lead to less usage of natural ressources in production.
