Drivers for OpenRAN
• Dependence on walled garden suppliers
• Frustration around the ability to change
• Open standards for RAN are achievable
• OpenRAN ecosystem in formation
• Not a revolution – need Carrier adoption
Operators need to start now or face the consequences

Solution to the Problem: vRAN Hotspots
16
Operators can save 49% in CAPEX
Front haul bandwidth
reduction
Dramatic cost reduction
Up to 10x compared to CPRI
(bandwidth proportional to data rate)
Increased distance
between RRU and VBBU
Significantly expanding choices
in network planning
Enhanced business agility
Provides network elasticity,
flexibility, ease of deployment, and
dynamic RAN

Summary
17
• Operators need to start now our face the consequences
• Virtualization enables 5G Hotspots
• Open standards and interfaces are achievable
• OpenRAN ecosystem in formation
• Not a revolution – need Carrier adoption
• vRAN is an edge application allowing 5G Hotspots
• Moving the core to the edge allows great cost savings against
declining ARPUs
With 4G & 5G Industry is about to see significant transformation
