Within a mobile communication network one can discern between base and hybrid base transmitter stations (BTS). The hybrid base transmitter stations differ from the conventional ones in that they use some alternative energy sources for power. This work presents a comparative assessment of life cycles of solar-powered hybrid BTS, and conventional BTS, using CML-IA method and CExD-based exergy analysis. Complete analysis was conducted, presenting the results of life cycle analysis for both systems. The results of assessment are presented using CML-IA and CExD categories at the mid-point level. The results also reveal a detailed insight into the mechanism of evolvement and sources of negative impact during life cycles of the analyzed systems. This establishes the basis for the development and manufacture of sustainable products and processes. Considering majority of factors, the use of hybrid BTS is justified. The exceptions are the categories of abiotic depletion, ozone layer depletion, and acidification according to CML-IA method, as well as the categories of non-renewable, primary and non-renewable minerals according to CExD method, which indicates greater negative impact in comparison with the conventional BTS. © 2017 Elsevier Ltd
