Krishna Yarlagadda and Saraj Mudigonda have recently been featured in Mobile Dev & Design with an article on how V.VoIP (Video and Voice over IP) can provide a superior multimedia experience by relying on LTE’s (Long-Term Evolution) available bandwidth and guaranteed quality of service.

The authors clearly describe the problem of existing OTT (over-the-top) clients in delivering V.VoIP services. Faced with either over-crowding an already busy cellular network or relying on a limited number of available Wi-Fi networks, they have turned to LTE to provide the user with dialler based V.VoIP calls.

The article describes how the advantages of adopting this technology have started to become clear, as V.VoIP is now referred to as VoLTE. Therefore, with guarantees like QoS, low latency and a dedicated bearer that enables a guaranteed bit rate for HD voice and video calls, we no longer have to utter the phrase “Can you hear me now?” again, but can start thinking of crisp-clear communication across all platforms.

 

As VoLTE is deeply integrated in the native dialler, features like Voice or Video Call, Short or Multimedia Messaging Service or Instant Messaging are pre-loaded on the handset with the possibility of OTA (over-the-air) updates to accompany any software revisions.

Operators will have to handle users moving between LTE areas and regions that will still be covered by legacy circuit-switched networks, but this will be transparent to consumers, who will even be able to switch to controlled Wi-Fi in enterprise scenarios. Therefore, a call can easily be transferred between smartphones, desk phones or tablets.

Finally, as the LTE network was designed with V.VoIP functionality in mind, OTT applications can easily take advantage of the resources at hand without leaving users dissatisfied due to call drops, latencies or no quality of service. As such, operators, equipment and device manufacturers and even software vendors have teamed up and are committed to create an LTE ecosystem. Furthermore, as smartphones and tablets today benefit from front-facing cameras, high resolution screens and multicore processors with on-chip voice, video and graphics accelerators that support enhanced real-time communication, VoLTE feels like the next logical step for the consumer as well.
