10 Differences Between lte and volte

The Difference Between LTE and VoLTE

What is LTE?

LTE, short for Long-Term Evolution, is a standard for wireless communication of high-speed data for mobile devices and data terminals. It is the technology behind 4G, providing faster data speeds and improved network performance compared to its predecessor technologies.

Examples of LTE:

– Mobile phone networks such as Verizon, AT&T, and T-Mobile use LTE to provide high-speed Internet access.
– LTE is used in broadband wireless access applications like fixed wireless broadband and portable devices.

What is VoLTE?

VoLTE, or Voice over LTE, is a technology that enables voice calls to be transmitted over LTE networks. Traditionally, voice calls were transmitted over 2G or 3G networks while data was transmitted over LTE. VoLTE allows voice calls to be transmitted as data packets over LTE, resulting in superior call quality and improved network efficiency.

Examples of VoLTE:

– Many modern smartphones and mobile devices support VoLTE, allowing users to make voice calls using LTE networks.
– Telecom operators worldwide, including Verizon, Vodafone, and EE, have implemented VoLTE to enhance their voice call services.

Differences between LTE and VoLTE:

Difference Area LTE VoLTE
Technology LTE is a standard for high-speed wireless data communication. VoLTE enables voice calls to be transmitted over LTE networks.
Voice Calling LTE does not natively support voice calls. VoLTE supports voice calls over LTE, providing superior call quality.
Network Usage LTE is primarily used for data communication. VoLTE utilizes LTE for both data and voice communication.
Call Setup Time LTE has a longer call setup time due to circuit switching for voice calls. VoLTE has a shorter call setup time as it uses packet switching for voice calls.
Call Quality LTE may have lower call quality compared to VoLTE due to limited bandwidth for voice calls. VoLTE provides HD voice quality with a wider bandwidth dedicated to voice calls.
Roaming LTE roaming is supported by many operators worldwide. VoLTE roaming is still limited and requires operator agreements.
Network Coverage LTE coverage is generally more widespread compared to VoLTE. VoLTE coverage is gradually expanding, but it may not be available in all areas.
Emergency Calls LTE requires fallback to 2G or 3G networks for emergency calls. VoLTE supports emergency calls directly over LTE networks.
Battery Life LTE consumes more battery power due to multiple network handoffs. VoLTE consumes less battery power as it allows for better network efficiency.
Call Continuity LTE does not seamlessly switch between voice and data during a call. VoLTE allows simultaneous voice and data usage during a call without disruption.


In summary, LTE is a standard for high-speed data communication, while VoLTE is a technology that enables voice calls over LTE networks. VoLTE offers advantages like superior call quality, shorter call setup time, and simultaneous voice and data usage. However, LTE has broader network coverage and supports emergency calls more reliably. The choice between LTE and VoLTE depends on specific requirements and preferences.

People Also Ask:

1. What is the difference between LTE and 4G?

LTE is a specific technology standard that falls under the broader term “4G.” While LTE is widely used and considered the most common implementation of 4G, there are other technologies such as WiMAX that also fall under the 4G umbrella.

2. Can I use VoLTE on any smartphone?

Not all smartphones support VoLTE. It depends on the device’s hardware and software compatibility. However, most modern smartphones offer VoLTE support.

3. Does VoLTE consume more data than regular voice calls?

VoLTE calls consume data from your mobile data plan, but the data usage is minimal. VoLTE packets are highly compressed, resulting in only a fraction of the data used compared to regular data services.

4. Can I make VoLTE calls while roaming?

VoLTE roaming is possible, but it depends on agreements between your home operator and the roaming operator. It is essential to check with your service provider to confirm VoLTE roaming availability in specific areas.

5. Are LTE and VoLTE available worldwide?

LTE has gained global acceptance and is widely available in many countries. However, VoLTE is still being rolled out in several regions, and its availability may vary depending on the network operator’s implementation and coverage.
