The Future of High-quality Voice

Along with making HD voice a reality, voice-over-LTE (VoLTE) provides a framework for a complex mix of video, messaging, and rich communications services (RCS). VoLTE promises the toll-grade quality you need to safeguard existing revenues while helping to fast-track compelling new services and more flexible business models.

But not without some challenges. VoLTE ranks among the most complex technologies mobile operators will ever deploy, and in today's fiercely competitive markets, the pressure’s on to get it right the first time. Evolving challenges include:

• Optimizing a multi-vendor network infrastructure
• Meeting high expectations for quality amidst increased subscriber mobility and network congestion
• Maintaining performance at the cell edge
• Leveraging the QoS and policy control mechanisms built into LTE

With so many variables in play, you can no longer risk relying on vendor data in predicting performance. Instead, service and equipment providers alike must qualify the functionality, resiliency, and scalability in their labs as they deploy and optimize new VoLTE services.
