Difference Between LTE and VoLTE

We are entering a new era in the mobile Internet. This is the transition time from 3G to 4G Internet. And there is a lot of buzz around the free voice calling and free unlimited 4G Internet offer made by Reliance Jio. Ever since Jio has made the offer, people have been asking questions if their phone supports 4G and also what is the difference between LTE and VoLTE. In this article, we will learn why people are asking about the terms like LTE and VoLTE. We will also learn how these two technologies are different from each other and which one is better.

What is LTE?

LTE is a mobile Internet technology standard. It’s an abbreviation of Long Term Evolution. You may wonder why LTE keeps popping up in context of 4G. Well, 4G (or fourth generation) is just a common name given to LTE technology. In short, 4G and LTE are synonyms.

Theoretically, LTE supports download speed of 100 MBits per second and upload speed of 50 MBits per second. Another variant of LTE, called LTE-Advanced, supports download speed of 1 GBits per second and upload speed of 500 MBits per second.

LTE is considered a technological evolution on both CDMA and GSM standards, that were used several years ago. Nowadays, LTE is fast becoming available across the globe and mobile Internet Service Providers are upgrading their networks from 3G to 4G. LTE is at present the fastest data transfer technology and soon it may become the most dominant among all the mobile Internet technologies being used.

What is VoLTE?

  • Full form of VoLTE is Voice over LTE.
  • VoLTE is pronounced as Vee O LTE.

VoLTE is a technology wherein you can simultaneously send voice and data over the network without diminishing quality of voice. In case of LTE, if you make a voice call and you also keep your data connection on, the quality of voice will reduce. So, in order to make a good quality voice call, you will have to switch off data. You may have noticed that in case of 2G and 3G, while you are making phone call, some phones will automatically stop data transfer so as to preserve the voice quality.

But in case of VoLTE, the voice quality will not reduce even if your data connection is on. With VoLTE it is very easy to transmit telephone conversation over the data network.

What are the Benefits of VoLTE over LTE?

It is easy to see that VoLTE is superior technology. It has following major benefits over LTE:

  1. Voice quality is better in VoLTE.
  2. You can keep data connection on while making a voice call.
  3. VoLTE can connect calls faster
  4. 4G VoLTE works on higher frequencies like 800 MHz and thus it can make connections much farther away from the mobile phone tower. In previous technologies, it was sometimes difficult to find a mobile signal.
  5. Use of VoLTE may save phone’s battery.
  6. VoLTE allows to you make video calls without using any third party apps.

What is the Difference Between LTE and VoLTE?

The following table lists the main differences between LTE and VoLTE.
