Safeguarding operator revenue against the OTT invasion


Operators and service providers will increasingly turn to VoLTE and VoWi-Fi to protect their lucrative voice business against the ever increasing rise of over the top (OTT) applications. This move to VoLTE and VoWi-Fi expects to generate a new stream of revenues for operators as it reduces subscribers’ dependency on OTT applications for voice calling in Wi-Fi areas and increases the potential for income generated by services and advertising.

The success of the adoption of VoWi-Fi resides in the ability of operators and service providers to deploy this technology/service right the first time and most importantly to optimize subscriber user experience by delivering unprecedented service performance, reliability and call quality.

To accomplish those goals, it is crucial that mobile voice providers obtain a unified view of deployed services, devices and overall network health. Critical is the ability to automatically collect real-time data from all deployed mobile devices, verifier probes and network elements.
