As predicted, 5G technology was the main focus of MWC19 Barcelona (formerly Mobile World Congress). Speaker after speaker touted the importance of deploying 5G as quickly as possible. Tech companies from all over the world showcased their 5G capabilities. Though 5G was a big topic at MWC the past few years, there’s clearly more urgency than ever. The impact of 5G will span industries and save lives.
Empirix announced today that a 3-year contract with a Tier 1 North American telecom operator was recently signed for $19M USD to improve the quality of performance of the operator’s mobile voice, VoWiFi and VoLTE networks, to score and increase customer experience satisfaction, and reduce OpEx related to mean-time-to-repair (MTTR).
This year, 5G took center stage and, for the first time that I can remember, car manufacturers showed up at MWC to demonstrate their connected and autonomous cars that 5G should “easily” enable.
To date, it appears most of the MSPs that have deployed VoLTE have relied on active testing to effectively “spot check” the end-to-end service improvements and overall performance. Very little appears to have been done to look at overall QoE across the entire customer base.
Service providers are demanding more from their customer experience and service assurance solutions because they have a keen awareness of the richness and value of the information that flows across their networks. Reliably and accurately extracted, this information can be used to help manage not just the network, but also the services offered and the devices deployed. Insights can be also be gained around the performance of providers’ vendors and—most significantly—the experiences and value of their customers.
By now, most of us involved within the Telecoms space will have heard about Voice over LTE. Like any new technology, it comes with a lot of hope and promise to improve customer experiences and reduce operating expenses, but what exactly is it and what challenges will it present for the service provider.
OGS selected the Empirix service assurance monitoring solution to gain visibility into the international connections providing carriers with access to its voice (both legacy circuit-switched and VoIP) and 2G/3G roaming services. With Empirix, OGS has uninterrupted visibility of network performance and service quality, as well as the ability proactively identify potential issues before they negatively impact customers. This flexible solution is capable of adapting to new technologies and innovative new services; OGS plans to extend the Empirix solution’s coverage to a recently announced LTE roaming service.
In one recent test Empirix was involved with, callers were complaining about long connection times and poor voice quality during a storm. The company involved conducted a test of its SBC to better understand the origin of the issue. During the test process, the organization discovered that, while having a registration flood of 10,000 concurrent SIP registrations, SIP call setup time doubled. Moreover, jitter increased on the SBC.
PESQ is a testing and monitoring related acronym that stands for Perceptual Evaluation of Speech Quality. Typically pronounced “pesk,” it is used as a means for automating the assessment of speech quality in communications networks (Unified Communications, VoIP, etc.).
Recently it was announced that Verizon secured the funding necessary to buy-out Vodafone’s 45% stake in Verizon Wireless. It is estimated that the deal will be finalized in Q1 of 2014.
