What is VoLTE, and How Is It Different from VoIP?

Voice is an essential yet straightforward service to billions of mobile users. It has become a killer application in the mobile network since its origin. The data traffic in the telecom systems is developing at a rapid pace. However, presently, it is vital to carry voice traffic for any mobile system to be commercially robust. The existing 2G/3G mobile systems use “Circuit Switching” to transfer voice traffic. In circuit switching, a dedicated channel or circuit is set to carry the voice traffic for the whole duration of a transmission.

On the other hand, in the case of IP networks, the voice traffic is transferred using IP packets over a data connection. For this, generally, “VoIP” or “VoLTE” solutions are used. This article highlights the fundamental differences between “VoIP” and “VoLTE” 4G solutions to enable potential users to recognize a better network for them. 

What is VoIP?

Before we jump into understanding the notion of VoLTE, we must first understand a little about the technology that came before it, which is VoIP. Short for Voice over Internet Protocol is a communications practice designed to deliver both multimedia and voice communications over Internet Protocol networks. The internet is the most significant and most immediate example. 

For years, voice services were delivered through a public telephone network. While this worked fine for many people, traditional analog services had its drawbacks. For example, adding new phone lines and equipment was almost always expensive. This is where VoIP came into the picture. It supports various call features, like voice services, fax, voice-messaging, and SMS text messaging, eliminating the need for extra equipment. 

However, VoIP was introduced when everyone was still using 2G or 3G networks for mobile devices. The years since then observed significant improvements in network connectivity. In addition, the arrival of 4G or LTE (Long-Term Evolution) meant better connectivity and faster services. 

What is VoLTE?

VoLTE, short for ‘Voice over long-term evolution,’ is a new standard for high-speed, wireless communication for data terminals and mobile phones. Unlike VoIP, VoLTE is a mobile-only technology that uses the 4G network to transmit voice calls. Of course, if you wish to get VoIP set up in your office, there should be some high-speed or strong broadband internet connection. But VoLTE takes things one step further by offering voice calls over 4G LTE cellular networks – the same kind your mobile phone is probably using, right. 

How is VoLTE different from VoIP?

Bandwidth 

VoIP can only be used across either 3G or 2G networks, while VoLTE functions exclusively over LTE and other 4G networks. The direct impact of this, combined with the use of advanced SIP protocol in the VoLTE network, gives it an advanced bandwidth. 

Immediate Voice Calls

VoLTE allows simultaneous voice calls and data usage. It is not possible to make a call on some smartphones while browsing the web. One has to drop from one app to perform the other.

Battery Life

VoIP runs on both 2G and 3G and continually switches between both depending on which one is faster and more effective, which takes a toll on the device’s battery life. VoLTE, on the other hand, continually uses only one reliable network, which has less tension on the device’s battery life, making it a better choice. 

Security and Reliability 

VoIP transfers call by sending data packets over the internet, voice, or otherwise, in no exact order and following no precedence. VoLTE, on the other hand, transfers voice data in high definition, without digitalizing it like VoIP, and gives the packets high priority. This ensures that the data sent over the VoLTE network is more safe and secure, and the transfer is more consistent than via VoIP. 

Connectivity 

VoLTE is braced by modern headsets, while VoIP is supported by phones and the web. The accessibility of VoIP-enabled phones, put together with its ability to work supported by the web, make the VoIP network easier to connect to and more available to a broader range of users. 

VoLTE and VoIP both have a lot to offer regarding voice data transfer. Therefore, we at SPARKs recommend going for VoLTE. VoLTE has better voice call quality due to the high-definition services compared to the standard rate offered by VoIP networks, making it an ideal pick of the two for voice quality. 

The price of VoLTE communication software offered by SPARK Services allows businesses of all sizes to provide their caller cultured communication services and ultimately a higher level of customer service.
