The principle of Cloud Radio Access Network (C-RAN) is the split of traditional base stations into Radio Remote Units (RRU) as low-cost wireless access points, and Base Band Units (BBU) in a centralized location. This new RAN paradigm accepts several choices for a functional split of the protocol stack, with different latency requirements to the fr...
Chapter
In the race towards 5G, NFV (Network Functions Virtualization) arises as one of the enabler technologies.

Chapter
Network Performance (NP)- and more recently Quality of Service/Experience/anything (QoS/QoE/QoX)-based network management techniques focus on the maximization of associated Key Performance Indicators (KPIs). Such mechanisms are usually constrained by certain thresholds of other system design parameters. e.g., typically, cost. When applied to the cu...
