Over-the-top voice providers like Skype have enjoyed a free run at the market for years. But typical OTT voice services fall short, offering poor voice quality and leaving the user with a smartphone battery lifespan that not even a fruit fly would envy.
Ready or not, Voice over LTE has arrived…
Recent analyst publication headlines confirm this sentiment:
“VoLTE – The next-generation tool for maximizing voice revenue”… RCR Wireless US
“VoLTE maintains momentum”… Heavy Reading
“Verizon Wireless remains focused on LTE coverage; VoLTE on deck”… RCR Wireless US
In most of today’s commercial LTE networks, voice service is based on traditional Circuit Switched (CS) technology in 2G/3G networks. We believe that operators can, and indeed need, to start planning today to offer Voice overLTE to their LTE users. The benefits of the service are just too great to ignore – better battery life, better audio, better reliability, more bandwidth. The list goes on.
But it does require some work. By planning now you could soon be competing with OTT services with your own offer – or alternatively, choosing to collaborate with OTT service providers.
In both cases, it’s important to understand how the user experience with OTT services compares with your communication services, including VoLTE, and plan how your network can evolve to offer the best quality, in a cost-effective manner.
For instance, specialized test methods are needed to verify the current consumption of VoLTE with different network configurations and in different radio conditions.
