This presentation highlights OpenRAN, the Capex/Opex savings, and how it’s being deployed in different parts of the world. Originally presented in an educational webinar specifically designed for Rural Operators. Presentation from the "OpenRAN – What It Is and What It Means for Rural Operators" webinar.

4. What is the Difference Between OpenRAN, O-RAN and vRAN?
Copyright Mavenir 2020 4
OpenRAN - disaggregated
RAN functionality built using
open interface specifications
between elements. Can be
implemented in vendor-neutral
hardware and software-defined
technology based on open
interfaces and community-
developed standards.
vRAN – an implementation of
the RAN in a more open and
flexible architecture which
virtualizes network functions in
software platforms based on
general purpose processors.
vRAN utilizing open interfaces
is one component of OpenRAN
O-RAN – refers to the
O-RAN Alliance or designated
specification. O-RAN Alliance is
a specification group defining
next generation RAN
infrastructures, empowered by
principles of intelligence and
openness.

The First OpenRAN Deployments are now underway
OpenRAN is more than virtualized RAN

6. Multi-Vendor RAN Interoperability using O-RAN Open Fronthaul
Copyright Mavenir 2020 6
§ Lower RAN TCO
§ Faster innovation from diverse
ecosystem
§ Increase RAN supplier diversity
§ O-RAN open Fronthaul interface
§ TIP Evenstar Project - $1000 Radio Unit
from MTI
§ Mavenir Base Band Unit

7. Drivers for OpenRAN
Copyright Mavenir 2020 7
• Dependence…on walled garden suppliers
• Frustration…around the ability to change
• Achievable…Open standards for RAN
• Formation…OpenRAN ecosystem
• Not a revolution – need Carrier adoption
• Hard decisions and risk taking
Operators need to start now or face the consequences

8. Open Source – Processes and platforms
Addressing 5G OpenRAN Challenges
Copyright Mavenir 2020 8
Bits/sec/hertz/$ - New TCO Business Models, Cost and Resiliency
Virtualization - All Elements Virtualized except the Radio
Open Interfaces – Resistance to Vendor Lock in
Low cost RRUs – Merchant Chipsets replacing proprietary design
New Suppliers - Open, Multi-Vendor, enlarged supply chain

9. OpenRAN

Open Interface Applications
on
Open Market Hardware
Anything else is considered proprietary
Major Ecosystem Influencers include:
Facebook, TIP, OpenCompute, O-RAN
vRAN is an
Application

10. System Integration
• Feature management
• Radio calibrations
• e2e system testing
• Fault and Performance Management
• NOC Integration
• KPI Management

The crucial role of cost to drive OpenRAN deployments
60% of operators believe that the lack of a low-cost RRU is a major obstacle or
slowing down OpenRAN deployments
35% of operators indicate cost savings as the main driver to adoption of OpenRAN
68% operators would consider deploying RRU and BBU from different vendors in
OpenRAN deployments

18. 3GPP is not an Open Standard
• Recommending 3GPP as an ‘open interface’ is not correct
– Example: The front haul interface between the remote radio unit and the baseband unit
(known as the Radio Access Network – RAN) where a specification was produced by
3GPP…but as many as 200 parameters of that interface were left to manufacturer
choice, allowing it to become a proprietary interface
• Interfaces are specified but not implemented
– X2 interface for internode handoff
– Not activated in vendor release

19. Open Standards can create Solutions to Address Documented
Security Issues
• Network solutions often come from different sources
ü Leads to the creation of a variety of testing procedures and methodologies to ensure that network
components support all the security and performance requirements of the network users
• Since most standards are also open, the methods for testing are also open
ü If the tests have full coverage for the security features that a network operator wants
• The outcome of the testing will be a network component that shows compliance
to the full coverage of test cases
• The advantage of open testing standards is:
ü Giving users and network operators the ability to see what security testing is performed and how
testing is performed
ü Knowing what security test cases are being performed allows the operator to confirm that the test
meets specific requirements

20. Summary
Copyright Mavenir 2020 20
•OpenRAN is real and underway
•Open standards and interfaces are achievable
•OpenRAN ecosystem in formation
•OpenRAN is Not a revolution – need Carrier adoption
•OpenRAN TCO – computed across whole business
•Moving the core to the edge enables 5G low latency services and a
profitable business plan.
With 4G & 5G, the Industry is seeing a Significant Transformation
