VoLTE is the next killer application for wireless. It will help LTE service providers to differentiate on superior call quality to compete against the likes of Skype, GoogleTalk, and other low-cost voice services. As with any new technology, test vendors need to launch solutions early to provide the tools equipment vendors and service providers need as they engineer their VoLTE device, networks, and services.

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. Read more »

The realities of 100% YoY traffic growth driving a need for a 30% YoY Capex increase do not fit with single-digit operator revenue growth. Without having a finely-tuned network to maximize revenues and intelligently deal with capacity issues, operators will be in a perilous situation. 

So how can mobile broadband networks most-effectively use a single IP-based infrastructure to support the unique traffic-handling and QoE requirements of converged voice, video, and data services? Since over-provisioning the network is cost-prohibitive, a positive user experience must be obtained through efficient partitioning of the available wireless network resources using QoS and policy management.
