Open RAN represents a significant shift in the Radio
Access Network (RAN) architecture. While traditional RAN
systems use proprietary, hardware-centric technologies,
Open RAN introduces an open, intelligent, and flexible
approach to network construction. The concept is
anchored on the disaggregation of hardware and software.
It leverages standard processors and open interfaces to
develop a robust and versatile network architecture.
The concept of Open RAN (often referred to as O-RAN) is
rooted in the standards set by the O-RAN Alliance.
Established in 2018 by a consortium of service providers,
the O-RAN Alliance aims to specify requirements and
harness the potential benefits of open RAN architecture.
O-RAN is characterized by four key functional blocks:
The above components work synergistically to form a
flexible, intelligent, and cost-effective RAN, which can
dynamically adapt to varying network demands.
