- Abstract
- Given today’s fast increase in data transfer volumes over fixed access networks, it becomes critical to have an accurate evaluation of the power consumption of access networks for environmental sustainability concerns. However, the current literature shows a high sensitivity of fixed-access network environmental impacts to the customer premise equipment (CPE) power consumption and do not offer accurate power data nor hotspot analysis capabilities. This paper presents a hybrid methodology combining measurements of up-to-date CPEs and datasheet analysis to develop a parametric power consumption model separating the contribution of the interfaces, enabling hotspot analysis. Applied to nine CPEs across different WAN technologies (xDSL, DOCSIS, PON, EoTP), the results reveal a significant power consumption variability—up to an order of- magnitude between CPEs and a factor of 2.2 for the same CPE with different operating modes. The model highlights that idle power contributions represent more than 98% of the average power consumption and demonstrates that the power consumption of a typical configuration of PON CPE is marginally higher than for a DOCSIS CPE. These insights offer a robust basis for enhanced analyses of the environmental impacts of access networks.
