“X2 latency kills throughput”
Inter-cell interference coordination (ICIC) and coordinated multi-point (CoMP) transmission require very short latencies between X2 interfaces to achieve real-time coordination between BSTs.

5G NETWORKS ● OPTIMAL, DYNAMIC TRAFFIC PATHS
5G networks will be increasingly dynamic, crowded with competing applications, and will require exceptional QoS.
The SDN controllers required to support multi-carrier aggregation, dynamic traffic engineering and performance optimization will require a real-time feed of network performance to optimize QoE.

VFN LOCALIZATION FOR LATENCY OPTIMIZATION
Distributed NFV is required to locate latency-critical network functions close to the ‘users’.
Hand-offs between carriers will impact latency. RAN sharing is an option.
Performance must be assured between NFVI hosting related functions to ensure end-to-end QoE is maintained.
