What is the Difference Between LTE and VoLTE?

🆚 Go to Comparative Table 🆚

The main difference between LTE and VoLTE lies in their capabilities to handle voice and data services. Here are the key differences between the two technologies:

  1. Data-only vs. Voice and Data: LTE (Long Term Evolution) is a data communication system and does not support voice calls while using data services. It provides high-speed data, but the quality of voice calls is not good when using data services simultaneously. On the other hand, VoLTE (Voice over Long Term Evolution) is a standardized system that allows users to make high-definition voice calls while using data services without any degradation in call quality.
  2. Network Type: LTE is a type of network, while VoLTE is a service offered on the network. VoLTE takes advantage of the high-speed LTE network to provide better call quality and faster call setup times compared to traditional voice calls made over older cellular networks like 2G or 3G.
  3. Simultaneous Voice and Data: LTE does not support voice and data services at the same time, meaning that data services are interrupted during a voice call. VoLTE, however, supports both voice and data services simultaneously, allowing users to use the internet and make calls at the same time without any interruption.

In summary, LTE is a high-speed data communication system, while VoLTE is a service that enables voice calls over the LTE network with improved call quality and faster setup times. VoLTE allows users to use voice and data services simultaneously, making it a more versatile technology compared to LTE.

Comparative Table: LTE vs VoLTE

Here is a table comparing the differences between LTE and VoLTE:

Feature LTE VoLTE
Full Form Long Term Evolution Voice over Long Term Evolution
Main Application Data communication system Data communication system with focus on voice calls
Voice and Data Services May or may not support simultaneously Always supports simultaneously
Voice Call Quality Poor when using data services Excellent even when using data services
Call Setup Time Slower than VoLTE Faster than LTE
Voice Over IP Requires separate software for video calls (e.g., WhatsApp, Skype) No additional software needed for video calls
Originated 2012 N/A

Both LTE and VoLTE provide high-speed internet service and support a 4G network. However, VoLTE is designed to offer better voice call quality and support for both voice and data services at the same time, unlike LTE which may not support simultaneous voice and data services.
