Energy consumption of telecommunication access networks

Figure 8: Georeferenced buildings with allocated street cabinets. For every connection point a set of meta data is available, which contains: • Connection point ID • Street cabinet ID • City • Street • House number • Number of subscribers • Cable length • Actual download data rate • VDSL2 data rate • VDSL2-Vectoring data rate This data allows geographical as well as statistical analysis. The data acquisition for HFC with DOCSIS 3.0 was far more difficult. Although the network areas could be identified in every city (see Figure 9), the spatial locations for the fibre nodes and for the CMTS (cable modem termination system) could not be obtained. 13
