Spirent Communications, the leader in testing networks, services and devices, announced today it is collaborating with Signals Research Group (SRG) to conduct a two-part study that evaluates the VoLTE User Experience by analyzing VoLTE voice quality, call performance and battery performance. The recently completed part one of this benchmark study compared VoLTE service to 3G Circuit Switched Voice and Over The Top (OTT) Skype Voice Service on the live network of a major US operator. The study revealed VoLTE is worth the wait and successfully delivers on the promise of superior Quality of Experience (QoE) and efficient use of network resources.
Some key highlights of the study include:
- VoLTE call quality, measured in terms of MOS using the industry-accepted POLQA algorithm, greatly exceeded that of 3G CS voice and was measurably higher than Skype Voice;
- VoLTE performance was considerably better than that of Skype when network loading and background applications were running on the mobile phone and transferring data with the network;
- VoLTE displayed significantly shorter call set up times than Circuit-Switched Fallback (CSFB);
- VoLTE required substantially fewer network resources than Skype which resulted in a far greater network efficiency and a meaningfully-longer estimated mobile battery life.
“Although conceptually I understood the potential benefits of VoLTE, it wasn’t until we analyzed the results that we collected with Spirent that I truly appreciated the incremental benefits that VoLTE offers,” commented Michael Thelander, the President of Signals Research Group. “I am really looking forward to the second part of our study when we have the opportunity to do sensitivity studies and take observations made in the field and confirm them in a tightly-controlled lab environment with Spirent’s test equipment and engineering resources.”
With OTT services such as Skype being readily available to mobile users, the driver behind VoLTE deployment is the opportunity for wireless carriers to realize the full potential of LTE and provide a guaranteed Quality of Service (QoS) for voice services on their LTE network. The study results validated that, although both VoLTE and Skype support HD Voice, VoLTE-specific features such as guaranteed bearer (i.e. ability to treat voice calls with higher priority over best-effort data packets) make the difference and deliver a much higher quality voice service to the mobile user. Additional positive network and user experience implications are expected as carriers push to launch improvements in their LTE deployments and expand LTE coverage.
“It was Spirent’s sincere pleasure to collaborate with SRG on this long-awaited VoLTE study,” said Nigel Wright, Vice President Spirent Communications. “We have been aggressively working with leading carriers, device and chipset manufacturers for the past several years on testing everything VoLTE and we are delighted to showcase the arrival of a superior experience for the mobile user.”
In this study, the Spirent Nomad User Experience Analytics System was used to measure the call quality (in terms of MOS) of the three voice applications and to control and capture performance data during the call setup and reliability tests. The Spirent Quantum Battery Life Measurement System was used to measure power consumption, current drain and the implied battery life for the three applications, plus Skype Video. Spirent Datum was used to simulate real world data usage.
The two measurement systems can also be used in a controlled lab environment with data captured from the live network to replicate many of the same test scenarios. This powerful ability enables the introduction of subtle changes such as different RF conditions and IP impairments to generate a more detailed VoLTE user experience analysis, which will be the focus of a second part of this benchmark study.

There is an ever-growing explosion of new devices that are connected to the Internet using “cloud” solutions. This rapid growth is creating a massive new demand for efficient access to data. And it’s not just about connecting to that data anymore. This new demand is bringing new issues and challenges and it is important for companies to scale for the coming growth. And with that scaling comes the need for greater security, gathering and data analysis, storage, connectivity and, of course, the...

Much of the value of DevOps comes from a (renewed) focus on measurement, sharing, and continuous feedback loops. In increasingly complex DevOps workflows and environments, and especially in larger, regulated, or more crystallized organizations, these core concepts become even more critical. In his session at @DevOpsSummit at 18th Cloud Expo, Andi Mann, Chief Technology Advocate at Splunk, will show how, by focusing on 'metrics that matter,' you can provide objective, transparent, and meaningfu...

Many private cloud projects were built to deliver self-service access to development and test resources. While those clouds delivered faster access to resources, they lacked visibility, control and security needed for production deployments. In their session at 18th Cloud Expo, Steve Anderson, Product Manager at BMC Software, and Rick Lefort, Principal Technical Marketing Consultant at BMC Software, will discuss how a cloud designed for production operations not only helps accelerate developer...

In the world of DevOps there are ‘known good practices’ – aka ‘patterns’ – and ‘known bad practices’ – aka ‘anti-patterns.' Many of these patterns and anti-patterns have been developed from real world experience, especially by the early adopters of DevOps theory; but many are more feasible in theory than in practice, especially for more recent entrants to the DevOps scene. In this power panel at @DevOpsSummit at 18th Cloud Expo, moderated by DevOps Conference Chair Andi Mann, panelists will dis...

If there is anything we have learned by now, is that every business paves their own unique path for releasing software- every pipeline, implementation and practices are a bit different, and DevOps comes in all shapes and sizes. Software delivery practices are often comprised of set of several complementing (or even competing) methodologies – such as leveraging Agile, DevOps and even a mix of ITIL, to create the combination that’s most suitable for your organization and that maximize your busines...

Up until last year, enterprises that were looking into cloud services usually undertook a long-term pilot with one of the large cloud providers, running test and dev workloads in the cloud. With cloud’s transition to mainstream adoption in 2015, and with enterprises migrating more and more workloads into the cloud and in between public and private environments, the single-provider approach must be revisited. In his session at 18th Cloud Expo, Yoav Mor, multi-cloud solution evangelist at Cloudy...

See storage differently! Storage performance problems have only gotten worse and harder to solve as applications have become largely virtualized and moved to a cloud-based infrastructure. Storage performance in a virtualized environment is not just about IOPS, it is about how well that potential performance is guaranteed to individual VMs for these apps as the number of VMs keep going up real time. In his session at 18th Cloud Expo, Dhiraj Sehgal, in product and marketing at Tintri, will discu...
