From Vision to RealityProprietary and Confidential3
Choosing an Effective Migration Path:Implement 5G xHaul in Phases Use existing MBH networks tomeet new requirements Steps:1. Capacity and accuratesynchronization2. Densification & Topology3. New servicesWebinar: 5G xHaul in Practice 12
5G – Phase 1 The evolution of services and applications takes time–Typically begins with capacity increase for eMBB Slow transition from non-standalone (NSA) to standalone (SA) mode vRAN and RAN split strategies vary: Various trends and timelines–Regardless of Fronthaul strategy, we see increase in BW demandfor Backhaul links leased from wholesale/transport providers Level of investment must cope with projected revenue streams Short-term demand for increased backhaul capacity and accurate synchronizationWebinar: 5G xHaul in Practice 13
How to Implement Phase 1Transport bandwidth relief Address eMBB and 4.xG traffic demands:– Increase backhaul transport links(self owned or leased)– Start with 1G to 10G transition,followed by 25G/100G linksClosing the transport network gaps CSG for immediate backhaul BW relief Maintain same backhaul architecture Same transport/wholesale assurance tools CSG for xHaul scenarios and split RANre-architectureTiming support as a service Distributed GM for new timingdistribution strategy Accurate timing distribution (GM, BC Class C) Timing as a service from transport/wholesaleproviderWebinar: 5G xHaul in Practice 14
