Among the findings, some relate to traffic management: "Traffic management limited network infrastructure spend:
- CSPs continued to implement policy management (PCRF/PCEF) solutions for fair usage and RAN congestion, limiting network overload from video and P2P traffic, primarily.
- Data caps and Wi-Fi offloading reduced RAN congestion and limited spending on mobile backhaul capacity.
- Diameter signalling traffic is increasing rapidly, but is mostly contained in the CSP’s high-capacity core network.
- PCRF is becoming a core network element for CSPs.
In additions, "Traffic management reduced investment in Business data services".
