What is VoLTE?

Since VoLTE is related to some of the earlier technologies, it is essential to start from scratch to understand why this new technology is necessary. VoIP stands for Voice over Internet Protocol, a communication method designed to deliver multimedia and voice communication over IP networks. The Internet is perhaps the most obvious and widely used example.

For decades, providers have offered only voice services on public telephone networks. These were analog services that most people use in their offices and homes. Connecting a traditional phone line was difficult. As a result, companies have difficulty maintaining their communication capabilities to adapt to their growing business. Adding lines was expensive but necessary. Mobility was also a significant issue.

When employees needed to receive calls, they had to sit at their desks. The ring is lost if the call comes while the person is away from their desk. They installed audio redirection and many other solutions, but they were more of a hindrance than a help.

Services were unstable and quickly interrupted. Bad weather made it challenging to get constant calls. Voicemail capability, for example, was a complete hassle to add to traditional lines. In addition, this connection required the purchase and installation of new and expensive equipment.

VoIP was introduced to help solve some of these significant issues. First of all, this technology is much easier to implement, maintain, and configure than traditional fonts. Additional support for new users can be obtained quickly, making it easier for companies to bring in new employees. There are no extra wires or phone lines to install. The whole process is fast and straightforward without compromising the quality of service. 

Due to the simplicity of installation and maintenance, it is easy to measure VoIP with the usual fluctuations in business. 

Voice, voice messaging, SMS, and even fax services are supported. While these features are great, mobility is one of VoIP’s essential benefits, which increases flexibility and overall productivity.

You require a laptop and connect it to a reliable internet connection. Fortunately, free WiFi is available everywhere in the 21st century.

In short, VoIP technology has taken a giant leap in communication. It took the transport potential of the twenty-first century and carved out a way forward that is still evolving. 

Now that you understand VoIP’s massive impact on the telecommunications industry, it’s time to introduce the next wave of innovation: VoLTE. People are talking about VoIP with the same vigor and enthusiasm as VoLTE. 

How does VoLTE work?

Voice over Long Term Evolution (VoLTE) is a modern standard for high-speed wireless communication for data stations and mobile phones. Unlike VoIP spread across many devices, VoLTE is only available on mobile systems. For example, you may need a high-speed internet connection to use VoIP in your office.

Since most companies are currently using this technology, this is not a problematic requirement. However, VoLTE has taken it further by using voice calls sent over 4G LTE networks. These are the same towers your smartphone is currently using.

Internet of Things

It is also essential to understand that VoLTE supports wearable technologies. Other devices connected to the Internet of Things are also supported. A recent study predicts that the Internet of Things will include 200 billion devices worldwide by 2020. 

The Internet of Things will likely infiltrate almost every device and area, including tablets, smartphones, manufacturing machines, industrial sensors, point-of-sale systems, etc. 

Why is VoLTE necessary for VoIP?

VoLTE is known for its excellent call quality. More information and data can be transmitted over a 4G connection than a 3G or even 2G connection. With VoLTE, users can get HD calling features virtually every time. High-level call quality is significant for companies. 

The enhanced connectivity and coverage that VoLTE offers are equally impressive. Even when you are not connected to a 4G connection, the service will automatically return to a 3G or 2G connection. The best part is that the connection will go to the fastest signal. In addition, VoLTE can deliver calls almost twice as fast as existing methods.

Another great advantage of VoIP technology over VoLTE is that users can simultaneously make data and voice calls. Previously, data transfer was not possible while using the network to make voice calls. It will transfer data at a much lower speed if you try, usually on 2G or 3G. VoLTE eliminates this problem by allowing faster voice and data calls to pass through the same network.

Suppose you want to send documents or photos while on a conference call; VoLTE makes it possible. Previously, you had to end the call, transfer the data, and call back after sending the information. 

Battery life is another significant improvement that VoLTE brings. Since the phone has to switch between 4G, 3G, and 2G connections less throughout the call, the battery life can be extended longer. 


VoLTE is still a new technology. The first commercial service was launched only in 2014 in Singapore. Due to the relatively young age of the technology, VoIP users have some inherent limitations that they may have to face. VoLTE is currently limited to mobile devices. Only 4G LTE networks support this new technology. 

However, looking at the list of advantages that VoLTE has over the old technology is reassuring that this development will continue to grow over the next few years. Everyone can be curious about what VoLTE will offer shortly. Businesses and employees, in particular, can benefit from these developments in many ways.
