Ixia introduces new VoLTE test application

February 24, 2012 by Ixia Blog Team

Voice and SMS services are the primary revenue sources for mobile operators, contributing nearly 80 percent of the overall revenue. As operators upgrade their 2G and 3G networks to LTE, they need the confidence that they can continue to provide customers with high voice quality and reliability. Voice over LTE (VoLTE) testing is a priority for these operators.

Ixia recently introduced a new test application to its IxLoad solution to measure voice quality end-to-end, from the cell tower through the core network. Operators can easily compare and contrast the voice quality of over-the-top (OTT) service to operator-provided voice services. Using best-in-class industry algorithms, operators can measure the mean opinion score (MOS) of voice quality before going live. Additionally, Ixia’s new application tests the functionality, scalability, and resiliency of LTE infrastructure components and new IMS networks that support VoLTE-based services.
