RIDING THE WAVE

What are key subscriber trends and carrier trends that disrupt?

Proprietary and Confidential

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

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
