Network challenges with declining ARPUs
• How to handle with projected Data volumes?
• How to support increased demand on low latency?
• How to decrease network costs to maintain profitability?
• How to maximise existing investments?
• How to migrate of centralized services to the edge?
• How to introduce 5G
• How to enable new business model

Low Latency – Micro Services at Network Edge
Bits/sec/hertz/$ - New Business Models, Cost and Resiliency
Virtualization - All Elements Virtualized except the Radio
Open Interfaces – Front haul and Networking
Low cost RRUs - Massive Densification
Spectral efficiency – Massive MIMO

10. Network Moving to the Edge
Copyright Mavenir 2019 10
• Bandwidth consumption continues to grow
• Networking applications demand low latency
– Proliferation of a gamut of use cases
• Tele-surgery
• Intelligent transportation
• Industrial automation
• Local offload
• Continuing to leverage a centralized control and
user plane is sub-optimal and expensive
– Building capacity with no revenue
• Cannot wait for 5G to evolve
• Leverages current radio and core network
technologies to deliver an optimal edge network with
lowest TCO

Operator Vendor Selection Mantra
“Nobody ever got fired if I buy from ……”
WRONG
100,000 redundancies
have been
completed/notified
in the last 6 months
with major Tier one
operators
Current business
models are not
sustainable within the
next three years.

shrinking to Two”

Summary
• Operators need to start now or face the consequences
• Without Virtualization there is no 5G
• Open standards and interfaces are achievable
• Not a revolution – need Carrier adoption
• RAN is an edge service
• Moving the core to the edge allows great cost savings against
declining ARPUs
• New business models will be enabled at the edge
WITH 5G INDUSTRY IS ABOUT TO SEE SIGNIFICANT TRANSFORMATION
