Cost and power consumption evaluation studies

This report cover the outcome of the evaluation of the technical solutions in terms of capital cost and energy consumption. The cost analysis focuses initially on the extraction of the expected system cost values for the proposed transmitter-receiver solutions and any added module in the system (e.g. the beam forming element). The study also considers the number of elements required for a fully deployed SDM architecture and compares this to other 5G solutions that are based only on the use of WDM. Similarly the power consumption values are extracted for the proposed solutions and the overall power consumption of the CO and the RRU sites is evaluated. Then the overall SDM-enabled fronthaul network cost is evaluated (including in the comparison both DRoF and ARoF) considering all the required elements and proposed technology solutions.
