Difference Between VoLTE & LTE

VoLTE is a standard for high-speed wireless communication for mobile phones and data terminals – including IoT devices and wearables. It is based on the IP Multimedia Subsystem (IMS) network, with specific profiles for control and media planes of voice service on LTE defined by GSMA in PRD IR.92. This approach results in the voice service (control and media planes) being delivered as data flows within the LTE data bearer. This means that there is no dependency on (or ultimately, requirement for) the legacy circuit-switched voice network to be maintained. VoLTE has up to three times more voice and data capacity than 3G UMTS and up to six times more than 2G GSM. Furthermore, it frees up bandwidth because VoLTE’s packets headers are smaller than those of unoptimized VoIP/LTE.

LTE is a standard for high-speed wireless communication for mobile devices and data terminals, based on the GSM/EDGE and UMTS/HSPA technologies. It increases the capacity and speed using a different radio interface together with core network improvements.[1][2] The standard is developed by the 3GPP (3rd Generation Partnership Project) and is specified in its Release 8 document series, with minor enhancements described in Release 9. LTE is the upgrade path for carriers with both GSM/UMTS networks and CDMA2000 networks. The different LTE frequencies and bands used in different countries mean that only multi-band phones are able to use LTE in all countries where it is supported.

Most probably, you might be using smartphones from past 6-7 years. Well, if we look around, we will find that the technology used in mobile devices keeps evolving. It all started with the 1G network and the operators are busy making 5G. 1G, 2G, 3G, 4G are the increasing generations of technology used in the mobile device.

There are few people who want to know the difference between LTE and VolTE. So, in this article, we will be discussing everything about LTE and VoLTE. Actually, these two technologies are quite different from each other. So, let’s explore more about LTE and VoLTE. So, let’s get started with LTE.

Its been a few years for the 4G network and we are right now in the transition time from 4G to 5G internet. Well, if you are Indian, then you might be well aware to the buzz created by the Reliance Jio. After the arrival of 4G connectivity, people have been asking questions like if their phone supports 4G, does the phone has LTE support etc.

In this article, we will be discussing everything about LTE and VoLTE. Actually, these two technologies are quite different from each other. So, let’s explore more about LTE and VoLTE. So, let’s get started with LTE.

What is LTE?

First of all, LTE which stands for Long Term Evolution is just a synonym for 4G connectivity. LTE is a mobile internet technology standard and it always pops up in the context of 4G. Now, the LTE technology has another variant which is known as LTE-Advanced. LTE and LTE-Advanced share the same technology, but LTE-Advanced is way more capable compared to the LTE.

However, in both of the mobile internet technology standard, speed is the only difference. The more capable LTE-Advanced supports the download speed of 1GBPS and the upload speed of 500MBPS. Whereas the LTE supports the download speed of 100MBPS and the upload speed of 50MBPS.

We won’t share any technical kinds of stuff in the post and will try to make things as simple as possible. So, in sort, LTE is a type of mobile internet technology which is very much similar to older 2G or 3G, but it offers faster speed compared to the previous ones.

So, What is VoLTE?

VoLTE is little more interesting compared to the LTE. VoLTE stands for Voice over LTE and it is mostly known for providing better voice quality during the calls. In LTE, if you make a voice call while connected to the data connection, the voice call quality reduce a bit. However, this thing won’t happen with VoLTE because its meant to send voice and data over the network without affecting the quality of voice.

Its worth to note that on older mobile internet technology – 2G and 3G doesn’t allow users to use the internet while making calls. As soon as you will make a phone call, the data transfer will stop immediately. These steps are taken to improve the voice quality. But, with LTE you can make calls while connected to the internet.

So, in short, VoLTE promises to deliver better voice quality even if your data connection is turned on because VoLTE makes it easier to transmit telephone conversation over the data network. In fact, you will feel a noticeable difference between in Voice Quality while making calls over LTE and VoLTE.

Which Is Better?

Well, you can take VoLTE as an upper variant of LTE. In my opinion, VoLTE is much better compared to the LTE technology. In fact, VoLTE connects calls much faster compared to the 2G, 3G, and LTE. Another interesting fact is that with VoLTE, you can make video calls without using any third party apps.
