5G and Edge Network Architectures

Global 5G Core Network Spending Forecast, 2018-2028: It's a Marathon

5G networks are the next step forward in mobile/cellular networks. They are characterized by very high downlink (and uplink) speeds, low latency, a flat network architecture with split control and user planes, and a services-oriented focus.

This report:

  • Provides a high-level overview of the 5G core network and system architecture

  • Shows how the various pieces work together without getting too bogged down in the details

  • Shows how an operator can migrate from their current LTE network to a 5G New Radio network complete with a 5G Core

  • Provides a ten-year forecast of mobile operator spending on 5G Core Network-based solutions in North America, Europe and Asia-Pacific.
