Recent voice over LTE testing has suggested that voice over LTE via generic access (VolGA) outperforms current 3G network call set up times by nearly 40%. The testing, conducted with Deutsche Telekom’s next generation mobile test network using LTE technology and a VoLGA solution from Kineto Wireless, delivers call set up times up to 65% faster than alternative LTE voice technologies, such as CS Fallback.
“We were confident that VoLGA would deliver a superior user experience, and now we have the test results to prove it,” said Franz Seiser, head of core network technology at Deutsche Telekom. “Customers who subscribe to next generation network services will expect performance to exceed today’s technologies, and it’s clear VoLGA can meet those expectations.”
The low latency of LTE access networks results in very high-speed message exchanges between the handset and network, enabling VoLGA to outperform even standard UMTS-based call-setup times. For operators intent on touting the overall speed of new LTE networks, this is a key performance metric.
“VoLGA is very focused on delivering a better user experience than 3G. Our testing has already shown quantitative improvements over CS Fallback in the areas of faster call-setup times, lower dropped call rates, and the ability to talk and surf the Internet at the same time,” said Patrick Tao, vice president of technology for Kineto Wireless. “VoLGA takes full advantage of emerging LTE technology to help operators deliver a truly compelling user experience for the LTE subscriber.”
