What is VoLTE and How Is It Different from VoIP?

You are currently viewing What is VoLTE and How Is It Different from VoIP?

Communications have undergone some major changes within the past century. In the past, we would simply pick up the phone to get in contact with someone. But in the 1990s, VoIP was introduced in the network market, gaining immense popularity for its efficiency and speed in transferring calls across wide distances. In the early 2000s, VoLTE came into the picture, by substituting Internet Protocols with advanced SIP protocols and increasing the network to depend on 4G, which was faster.

This article highlights the basic differences to allow potential users to identify a better network for them.

 

What is VoIP?

Before we dive into understanding the concept of VoLTE, we must first understand a little about the technology that came before it: VoIP. Short for Voice over Internet Protocol, this is a communications methodology designed to deliver both multimedia and voice communications over Internet Protocol networks, with the internet being the biggest and most immediate example.

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

However, VoIP was introduced at a time when everyone was still using 2G or 3G networks for mobile devices. The years since then observed major improvements in network connectivity. 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 relatively 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. If you wished to get VoIP set up in your office, you would need to make sure that some kind of high-speed or broadband internet connection was present. But VoLTE takes things one step further by providing voice calls over 4G LTE cellular networks – the same kind your mobile phone is probably using right.

 

How is VoLTE different from VoIP?

  1. Simultaneous voice calls

VoLTE enables simultaneous voice calls and data usage. On some smartphones, it is not possible to make a call while browsing the web. One has to drop from one app in order to perform the other.

  1. Battery Life

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

  1. Bandwidth

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

  1. Connectivity

VoLTE is supported by modern headsets while VoIP is supported by phones and the web. The high availability 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 accessible to a wider range of users.

  1. Security and reliability

VoIP transfers call by sending data packets over the internet, voice, or otherwise, in no specific order and following no priority. 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 reliable than via VoIP.

 

VoIP and VoLTE both have a lot to offer with respect to voice data transfer. We recommend going for VoLTE. VoLTE has better voice call quality due to the high-definition services when compared to the standard quality offered by VoIP networks, making it an ideal pick of the two for voice quality.

About Robert E. Allen Jr. A Journey of Integrity, Innovation, and Impact Welcome to my corner of the web, where the confluence of technology, entrepreneurship, and ethical business practices come to life. I'm Robert E. Allen Jr., a proud native of southern Ohio, where my roots run deep into the fabric of community and hard work. My journey in the tech world began at Shawnee State University, a chapter filled with exploration and the beginnings of a lifelong passion for computer science. However, my academic path took a turn toward the prestigious halls of Penn State, where I completed my degree and set the foundation for what would become a nearly three-decade-long adventure in business. Building an Empire on Principles Nearly 30 years ago, I embarked on an entrepreneurial journey, not just to start a business, but to build an empire defined by a commitment to ethical practices and community service. Inspired by the Rotary four-way test—Is it the truth? Is it fair to all concerned? Will it build goodwill and better friendships? Will it be beneficial to all concerned?—my business philosophy centers on these questions, guiding every decision and interaction. This ethos has not only shaped my professional life but has also fostered a culture of integrity, trust, and mutual respect within my company and with our clients. A Family Man at Heart Beyond the world of bits, bytes, and business, my life is rich with love and laughter, thanks to my wife and our two wonderful daughters. They are my why, the reason behind every late night, every early morning, and every decision to push the boundaries of what's possible. Together, we've created a life filled with memories, learning, and love—a true testament to the balance between professional ambition and personal fulfillment. Looking Forward As I look to the future, my goal is to continue leveraging technology to make a positive impact on the world, guided by the principles that have brought me this far. I strive to innovate, to lead with integrity, and to inspire those around me to do the same. Whether through my business endeavors, community service, or simply by being a role model to my daughters, my journey is about creating a legacy that transcends technology—a legacy of positive change, ethical leadership, and a commitment to making the world a better place for future generations. Thank you for visiting my site. I hope to not only share my journey with you but also to inspire you to pursue your passions, lead with integrity, and make a meaningful impact in your corner of the world.
