Data Consumption is Exponential…Revenue is Not…
A large undertaking: Reduce Opex and Capex while increasing ARPU and margin
▪ Most valuable asset is you and your team
▪ Largest expense is you and your team
Operational efficiency is critical:
▪ Forced to do more with the same resources
▪ Resources need to shift to customer acquisition and retention
▪ Network functions need to be collapsed and automated… driven by software

Bandwidth growth is exponential
▪ Fiber is the path to long-term sustainability
▪ Offers virtually unlimited bandwidth
▪ Allows network to be built “once”

Consolidation of functions
▪ Access
▪ Aggregation
▪ Edge routing and subscriber management
Benefits of consolidation
▪ Centralizes policy
▪ Removes network bottlenecks
▪ Fewer systems to purchase
▪ Fewer systems to provision and manage
