Case Study: Telefónica achieves unified global performance assurance and improved QoE with Accedian Networks

Telefónica Standardizes Globally on Accedian Performance Assurance Solutions to Enhance Customer QoE

Telefónica, a global telecommunications provider serving 341 million customers across brands like Movistar, O2 and VIVO, needed to protect and improve customer Quality of Experience (QoE) as subscribers migrated to LTE. Because voice still rode 3G and data use grew rapidly, Telefónica required ubiquitous, real-time visibility across multi-vendor, asymmetrical metro and backhaul networks, multi-class-of-service monitoring and fast, scalable instrumentation to reduce call drops, prioritize signaling/voice, and accelerate LTE ROI.

Accedian delivered a unified performance-assurance solution—SkyLIGHT platform, Nano Smart SFP modules and 1/10GbE performance elements—deployed first in Brazil and rolled out across Latin America and Europe. The solution provided one-way, multi‑CoS monitoring and centralized control, reduced call drops, improved availability and bandwidth optimization, enabled eight traffic-priority tiers per site, extended 3G life, supported major events and won Telefónica’s global RFP, giving the operator real-time QoS/QoE visibility and a scalable foundation for SDN/NFV and 5G migration.
