Let’s start with a definition and a reminder.
What is VoLTE?
VoLTE stands for Voice over Long Term Evolution.
It’s a wireless communication technology transmitting voice with data packets using 4G networks.
As a reminder, 4G means high-speed data coverage but is a non-voice, data-only technology.
VoLTE can be used for IoT devices, data terminals, wearables, and mobile phones.
- For mobile users, 4G VoLTE means HD voice and video calls, better coverage, and battery savings.
- For connected objects (IoT devices), having 4G LTE with VoLTE technology means that IoT apps can use the same communication channel for bi-directional human voice interactions (from vending machine to alarm panels.)
4G LTE investments continue to grow steadily in 2020, according to the Global mobile Suppliers Association (GSA).
The association reported 224 commercial VoLTE networks in 104 countries in October 2020.
The Internet of Things and VoLTE
With the sunset of 2G and 3G networks on the horizon, the IoT industry is quickly migrating to LTE to improve reliability and ensure the longevity of technology investments.
Highly efficient LTE Cat. 1 is the favored connectivity choice for industrial applications that are not dependent on speed but still require 4G reliability.
Gemalto has globally demonstrated how leading-edge Cinterion™ VoLTE Cat. 1 modules are helping bring 4G IoT solutions to the next level offering simultaneous voice and data over IoT-optimized LTE for the first time.
Cinterion VoLTE technology (Voice over LTE)
As the IoT expands and spreads into new areas connecting machines to machines to people, VoLTE Cat. 1 technology will develop your ability to collaborate, communicate and interact - both from a human and device perspective.
Voice to communicate in the IoT
A recent white paper by Strategy Analytics highlights the role of speech, the most efficient means of human communication, in the IoT.
Adding VoLTE to Cat.1 networks offers the operator the ability to enhance existing and new IoT applications requiring regular human voice interactions.
These applications range from alarm panels, vending machines, parking payment machines, connected elevators in smart buildings, to customer service support buttons, and more.
Leveraging VoLTE technology enables a more flexible user experience and opens more business opportunities for IoT applications.
Create a new IoT experience with VoLTE
Strategy Analytics forecasts that voice could capture up to 12% of Industrial IoT applications by 2022.
