WHAT OPERATORS WANT
Agility
Flexibility
Efficiency
• Helps to launch newer features with faster
time to market
• Helps in adopting the fail fast principle
• Helps in going after newer revenue
opportunities
• Getting bug fixes faster
• Hosting functions in different types of
infrastructure (public/private/hybrid)
• Avoids looking to a specific infrastructure
• In terms of infrastructure resource
utilization
• Reduce power utilization
• Reduce cost
Performance
Elasticity
Cost Reduction
• Leading edge performance needed to
cater to high-speed data rates, high
number of signaling transactions and lower
packet latency
• Cater to needs of 4G as well as for 5G
• Automated scaling up or down as per
the needs of the network
• Helps improve efficiency
• Reduce both CAPEX and OPEX
• Virtualized software-based solution
• Automation and Orchestration helps
reduce OPEX

Need to address biggest cost factor for operators
RAN IS
60%
OF CAPEX AND OPEX
it is the most important cost factor to
focus on in telecom

ZERO TOUCH PROVISIONING (ZTP)
02
Zero Touch Provisioning
RIC
Auto-provisioning without manual
intervention
Automated installation and
configuration
Decreases complexity
Reduction in time,
errors and cost
Relatively safe for RAN installation
Easier to deploy 100s/1000s of sites
as no site visit is needed

OPEX REDUCTIONS WITH AUTOMATION – CI/CD
03
With Automation
Without Automation
CI, CD
• Sending people on site for software
upgrades and testing
• ~40% savings in OPEX vs. traditional
• No single point of failure on site

AI/ML
04
AI/ML is key for
intelligent management
and operations of the
network
Networks are getting
complex and the only way to
manage such networks is by
having self learning and self
decision making to automate
management and operations
of networks
O-RAN has natively built-in
AI/ML framework into RAN
architecture with Near-RT &
Non-RT RIC functions
O-RAN architecture with
the help of rApps &
xApps integrates AI/ML
based decision making
ML models are trained in
Non-RT RIC rApps based
on data received from
different functions in the
network for analysis
