LTE vs VoLTE, Which one is better and why?

LTE vs VoLTE, Which one is better and why?

Since the time when 4G came in our couuntry or across the globe, everyone is providing LTE and VoLTE services saying you can have HD Voice calls and more. But to be honest, I feel absoultely stunned by this move, since I don't know what are the basic differences between LTE and VoLTE and how are they better in our communication. So, here I'm telling you all about LTE and VoLTE along with the necessary details:

First of all, let's all learn something about HD Voice Calls:


What is HD Voice Calling? 

Technically, if you have attended any 4G call, you would have seen the call quality is much much better than normal call. This is what we call HD calling. Remember for HD call to take place both persons have VoLTE enabled.

Now, let's have some brief idea about LTE and VoLTE and then compare there working sections:


What is 4G LTE?

The term 4G LTE is really two terms. 4G means the fourth generation of data technology for cellular networks ̶ following 3G, the third generation. LTE stands for Long Term Evolution and is short for a very technical process for high-speed data for phones and other mobile devices. Together, they make 4G LTE ̶ the fastest 4G service available today.

Connection Speed:

Being the fastest network available means download speeds four to five times faster than 3G networks, which rivals some home broadband connections. The real hook, though, is the fact that consumers don’t have to be at home to appreciate these speeds. Consumers can access the internet wherever there is coverage with any 4G-enabled device, including smartphones, tablets and mobile hotspots.

Data Downloading:

The term data means anything other than SMS (simple text messages) and phone calls. Everything else including downloading apps, checking email, watching a YouTube video or downloading a picture requires the use of data. In short, data means everything that a smartphone or tablet is needed to do.

Quicker Speed:

The speed, then, is exactly why so many people are excited about 4G LTE. Cellular data is a part of many peoples’ lives and the ability to utilize and experience the internet in a quicker, richer way opens new possibilities for both business and personal lives.

Now, let's learn more about VoLTE and why it is superior than LTE


What is VoLTE?

VoLTE brings voice call and video call to a brand new generation! VoLTE (Voice Over LTE) means connection of voice and video call through 4G LTE network. You can now enjoy a FREE upgrade to experience voice call with speedy connection and video call with high quality!

Benefit of using VoLTE

Enables faster voice call set-up

Making call connection via 3G network takes around 7 seconds to connect. But now, if both users are enjoying VoLTE, the call connection just needs as fast as 1 second! If calling friends using 3G network via VoLTE, the call connection just takes around 4 seconds. If both users are enjoying VoLTE, the call connection just need as fast as 1 second!

Enhances video call quality

Under VoLTE connection, the visual can be very clear without any grids. Traditional video call connected under 3G network. Video call connected under VoLTE, with resolution reaches up to 640x480pixels. Obviously the visual is very clear with high quality.

Enables instant switching between voice and video calls

When voice call is processing, user can switch the call to video call with just one click on a button! User can switch back from video call to voice call in the same way also, simply convenient and easy! Switch between voice and video call by pushing the button on the top right corner.



LTE was designed to provide higher data transfer rates, while VoLTE is specifically targeted at improving calling quality.

During a call, we need constant flow of data(voice) from one side to another. Now data can be transmitted in two ways.

  1. By Forming an end to end connection and transferring data via it (Circuit Switching).
  2. By dividing data into small packets and sending them to other side via different paths


Must have items for using VoLTE:

  • 1. Use handset supporting VoLTE
  • 2. Have the handset software upgraded to the latest version (Applicable to Android phones) .
  • 3. Activation the VoLTE function of the handset

I hope you get some rough idea about LTE and VoLTE now, and you proudly can boast about this new learning. Don't forget to share this article if you find it Useful!
