5G System Technological Enhancements Provided by Fiber Wireless Deployments

The 5G STEPFWD projects proposed a new network architecture at both the edge and fronthaul/midhaul domains that utilized the Ultra Dense Wavelength Division Multiplexing (UDWDM) technique in order to support a high number of small cells at the access domain; this was realised through the application of an UDWDM Passive Optical Network (PON). Thus, the small-cells were connected to the PONs through fiber links between two Optical Line Terminals (OLTs), and/or by point-to-point fiber links, and/or small-scale fiber protection rings among locally adjacent Optical Network Units (ONUs). The 5G STEPFWD project defined a set of objectives that referred to the optical, wireless, and optical-wireless domains of the network, which were presented as follows: At the wireless domain, 5G STEP-FWD aimed to: 1. assess fundamental trade-offs between spectrum and infrastructure sharing, in multi-network operator environment; 2. develop a disruptive device- or user-centric cellular concept, which allowed smart overlaid peer-to-peer communications; 3. introduce novel base station switching off schemes for mmWave-based HetNets with renewable energy capabilities; 4. re-think the concept of antenna design for mmWave hyper dense network, by configuring it in a flexible and adaptive manner. At the optimal domain, 5G STEP-FWD aimed to: 1. develop efficient optical transceivers that were compatible with the UDWDM technology; 2. investigate PON configurations that were UDWDM-compatible, targeting to minimize the cost, maximizing the ONU population and satisfying QoS; 3. develop innovative wavelength/bandwidth allocation techniques applicable to ring-based architectures that interconnect multiple PONs. At the optical-wireless domain, 5G STEP-FWD aimed to: 1. propose a novel converged mmWave-UDWDM PON network design that interconnected multiple PONs; 2. propose novel modulation techniques for enabling the transmission of mmWave signals over UDWDM-PONs; 3. design an SDN-based architecture for the efficient utilization of the multi-PON wireless and optical resources.
