The OpenRAN architecture, empowered by intelligence and openness principles, is the foundation for building the virtualized RAN on open hardware and cloud, with embedded AI-powered radio control. The architecture is based on standards defined by O-RAN Alliance, which completely support and are complementary to standards promoted by 3GPP and other industry standards organizations.

1. OpenRAN
AN INTRODUCTION

2. THE OpenRAN INITIATIVE
OpenRAN is the movement in mobile networks and
telecommunications to improve the efficiency of RAN
deployments and operations.
According to Nokia, OpenRAN has been touted as the
‘next big thing in wireless’

3. THE ORAN ALLIANCE
A BRIEF BACKGROUND
The O-RAN Alliance's goal is to provide strategies
to build RAN solutions enabling different COTS
parts from vendors with AI/ML for more efficient
network management and orchestration
• Foundation was laid in 2018
• Members include close to 30 operators &
more than 200 vendor companies

8. OpenRAN
BENEFITS
No dependency on H/W & S/W
Simplified operation/maintenance
Reduced CAPEX & OPEX
Quick deployment of new features
Easy rollout of 5G services
Easy scalability with
microservices -based architecture

9. OpenRAN
CHALLENGES Major RAN vendors not
open to adopting interfaces
Multi-vendor approach leads to increased
complexity & difficult to maintain system integration
Adoption of a particular standard creates
competition between organizations.
Tussle between parties on the ownership
front with multiple vendors in one system

10. HOW WILL OpenRAN
TRANSFORM 5G
OpenRAN is expected to pave the path for
greater innovation and early deployment
of 5G.
It would help in the adoption of innovative
5G use cases with the architecture and
openness that it provides.
