A Holistic Study of Power Consumption and Energy Savings Strategies for Open vRAN Systems
Report
As mobile traffic increases, mobile networks are transforming into more software-driven, virtualized, flexible, intelligent and energy efficient systems. These trends have spurred significant changes in the core network design with the advent of Software-Defined Networking (SDN) and Network Functions Virtualization (NFV), which have enabled building more agile, less expensive network entities. However, the radio access network has largely remained unchanged until recently, even though much of the CAPEX and OPEX in building and managing networks results from the Radio Access Network RAN.
