At A Glance – VoLTE – Voice over Long Term Evolution

Hark the herald VoLTE technology

VoLTE stands for Voice over Long Term Evolution. LTE itself is a standard of wireless broadband communication for devices that increases capacity and speed. As it is incompatible with 2G and 3G, LTE is often marketed as 4G LTE. So, voice over LTE simply refers to voice calls that are facilitated by a 4G LTE network.

Following the development and deployment of 5G networks, VoLTE has become more prominent. In a 2017 report, Ericsson predicted that 20 per cent of the world’s population would subscribe to a 5G network by 2023. The research also suggested that VoLTE subscriptions would see a 746 per cent increase within the same timeframe. Other estimates tell a similar story – by 2022, Allied Market Research expects the VoLTE market to experience a compound annual growth rate (CAGR) of more than 50 per cent.

The popularity of VoLTE can be attributed to various factors, one of which is the mass migration to 4G. Demand for video conferencing has also driven the market as businesses look for more efficient ways to bring connective technology into their infrastructure. In addition, VoLTE ties in with the Bring Your Own Device (BYOD) trend. As more people bring their personal devices into the workplace, they inadvertently use them for voice and video calls. VoLTE is helping to support growing usage at the same time as improving user experience.

The advantages of VoLTE include better voice and video quality, more efficient use of spectrum, and advanced content sharing within calls. However, today’s voice calls only use VoLTE if both callers are using compatible LTE networks. 5G promises to make higher quality calls more accessible to more people, and it will use existing VoLTE technology as a spring board. No doubt improved voice calls will have a knock on effect in products and services that utilise vocal commands, fuelling the voice economy.
