A. You’ll enjoy a slew of advantages if you choose our products and services. Flexibility of call quality analysis, 5G testing, and proactive troubleshooting are just a few of the ways we can assist you in improving your network.
A. As long as you provide us with 30 days’ notice in writing, you may end the contract at any time without penalty. This allows us to better allocate our resources.
A. Predictability is essential to keep doing it on a regular basis. With our tools and solutions for audio quality analysis you can do it regularly e.g. every hour, every day, or even in real-time. Make sure each probe receives the most current feedback and is working toward the next scheduled review. Keep at least two probes observing the quality of the work at all times, and of course, Sevana has got your back. AQuA is used for end-to-end testing. It is working in the same manner as POLQA and ViSQOL. Please refer to this FAQ further down regarding these technologies.
A. In addition to the Sevana smart city solutions, the company’s higher management has made another beneficial step. The procedure is always evolving. It’s all about improving the quality of life by measuring noise pollution, managing waste collection and sorting, and a host of other things.

The MOS is expressed as a single rational number, typically in the range 1–5, where 1 is lowest perceived quality, and 5 is the highest perceived quality.
POLQA is the global standard for benchmarking voice quality of fixed, mobile and IP based networks. It was standardized by the International Telecommunication Union (ITU-T) as Recommendation P.863 in 2011 and can be applied for voice quality analysis of VoIP, HD Voice, 3G, 4G/VoLTE and 5G networks. Learn more about AQuA, which is an alternative technology for perceptual voice quality analysis.
Virtual Speech Quality Objective Listener (ViSQOL) is a signal-based, full-reference, intrusive metric that models human speech quality perception using a spectro-temporal measure of similarity between a reference and a test speech signal. In fact ViSQOL is a technology similar to POLQA and AQuA. Contact us to learn more about AQuA tool and receive free evaluation.
Quality of experience (QoE) is a measure of the delight or annoyance of a customer’s experiences with a service (e.g., in telecommunications it’s a phone call, stream broadcast e.t.c). QoE focuses on the entire service experience; it is a holistic concept, similar to the field of user experience.
ITU-T P.564 is an international standard for сonformance testing for voice over IP transmission quality assessment models. It utilizes both packet analysis and acoustic analysis of the call to predict more reliable MOS score than ITU-T G.107 (E-Model). Alternative technology for P.564 is a real-time library of PVQA Server.
