Voice-over-LTE is a much awaited technology that has seen many trials since its first commercial launch by Korea’s SK Telecom and MetroPCS in the US in 2012. With 279 LTE networks now deployed around the world, according to the GSA, it is expected that 2014 will be the year that will see VoLTE more widely launched.

VoLTE promises clearer calls that will connect much quicker and use less bandwidth, thus the move from legacy circuit-switched networks onto LTE networks is vital. Successful VoLTE calls require VoLTE technology in the network along with compatible devices, such as those made by Samsung, and these have already been used in trials by Verizon, AT&T and EE, though the GSA now lists 329 devices that support VoLTE’s W-AMR codec.

What is also important are the other services, and therefore monetisation opportunities, that VoLTE enables over the network—how this technology is becoming the evolution of voice services and how it might bring different ecosystems together to provide great customer experience.

VoLTE will be a hot topic at the upcoming LTE World Summit in June, but also later in the year the LTE Voice Summit 2014, a dedicated voice event, will present speakers from Orange, Vodafone, EE, Telefonica, SK Telecom, LG Uplus and many other operators. At the event these operators will share their experiences and provide an insight on use and test cases of VoLTE deployments, along with discussing the fundamental reasons why carriers are implementing VoLTE.

Will it be successful in creating another revenue stream for operators, or is it just to eliminate the treat by OTT players? Come and join this debate at the LTE World Summit on 24-25th June, and at the LTE Voice Summit on the 7-8th October 2014, London.

  1. It’s a demand and coverage issue. Carriers should fully embrace voice and sms offload onto all wifi as a way to rapidly evolve to complete VoLTE and shutting down 2 and 3G networks rapidly. But they don’t really think this way, do they?
