Pain points ? Bandwidth usage is independent of user?s load ? Highly inefficient ? No path diversity ? Low fault tolerance ? Separated transport management (FH - BH) ? Complexity and cost ? Cloud-RAN Functional split ? Fixed and Static 5G-Crosshaul: 5G Mobile Transport Network 5G Cloud-RAN will be transformed to a packet-based network. FH and BH will converge to an integrated transport network (Crosshaul): ? BW usage dependent on user?s load ? Higher efficiency ? Enables path diversity ? Packet-based Routing? Higher fault tolerance and load balancing ? Unified management platform (FH + BH)? Lower management complexity and cost ? Cloud-RAN Functional split and placement? ? Variable ?
