The stake of the Voice Quality Challenge

How to ensure a successful launch of VoLTE and VoWiFi Devices and Services.

As of February 2019, the Global Mobile Suppliers Association announced that 253 operators are investing in VoLTE in 113 countries which represents an increase of 35% more operators than 12 months ago.


This number shows that the consumer Voice experience is a key point which is seriously considered by Telecom professionals.

If many operators across the world are continuously investing in Voice over WiFi (VoWiFi) and Voice over 4G (VoLTE) technologies it is because these will improve the voice experience, better connection time and better overall coverage and more importantly it is a necessary step to full IP network.

To strengthen the above and unsurprisingly, according to a consumer survey by Deloitte the number one reason in US why end users are leaving a mobile network is the voice quality. Even though consumers are using their devices in many ways, voice quality remains number one KPI for them.

Therefore, to assure successful launch of VoLTE and VoWiFi devices and services, it is very important for Mobile Operators and Device Manufacturers to test and evaluate all the important aspects that will matter and affect the end user experience.

This is where SmartViser expertise comes to help with an end to end solution that facilitates quality of experience (QoE) testing and measuring.

Indeed our Viser Premium tool suite enables teams to automate any user action and to record all key metrics -Audio Quality, Call set up time, Call connection rates, Battery life impact, Call interoperability, Call drop, etc.-

SmartViser viSer Premium suite already supports Network Operators in the testing of all possible combinations from cross RATs, cross operators, asynchronous events, handover conditions (mobility) and many more.

We are pleased to announce for the Mobile World Congress event that we have just added to our KPIs’ list the Voice Quality MOS scoring based on POLQA™* industry standard.

The aim of this is to contribute to the optimal successful launch of VoLTE and VoWiFi devices and services by Mobile Network Operators.
