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.

My team embarked on building a data lake for our sales and marketing data to better understand customer journeys. This required building a hybrid data pipeline to connect our cloud CRM with the new Hadoop Data Lake. One challenge is that IT was not in a position to provide support until we proved value and marketing did not have the experience, so we embarked on the journey ourselves within the product marketing team for our line of business within Progress.

DevOps is often described as a combination of technology and culture. Without both, DevOps isn't complete. However, applying the culture to outdated technology is a recipe for disaster; as response times grow and connections between teams are delayed by technology, the culture will die. A Nutanix Enterprise Cloud has many benefits that provide the needed base for a true DevOps paradigm.

Providing the needed data for application development and testing is a huge headache for most organizations. The problems are often the same across companies - speed, quality, cost, and control. Provisioning data can take days or weeks, every time a refresh is required. Using dummy data leads to quality problems. Creating physical copies of large data sets and sending them to distributed teams of developers eats up expensive storage and bandwidth resources. And, all of these copies proliferating...

In recent years, containers have taken the world by storm. Companies of all sizes and industries have realized the massive benefits of containers, such as unprecedented mobility, higher hardware utilization, and increased flexibility and agility; however, many containers today are non-persistent. Containers without persistence miss out on many benefits, and in many cases simply pass the responsibility of persistence onto other infrastructure, adding additional complexity.
