VoLTE calls, or Voice over Long-Term Evolution calls, are voice calls made over a 4G LTE (Long-Term Evolution) network instead of traditional 2G or 3G networks.
Key Aspects of VoLTE
- Definition: VoLTE allows voice calls to be transmitted as data packets over the 4G LTE network.
- Improved Voice Quality: VoLTE typically offers significantly better voice quality compared to 2G or 3G calls, often described as high-definition (HD) voice.
- Faster Call Setup: Calls connect more quickly with VoLTE compared to older technologies.
- Simultaneous Voice and Data: You can use data services (like browsing the internet) while on a VoLTE call, which is not always possible with older networks.
- Efficiency: VoLTE is more spectrally efficient, meaning it can carry more voice and data traffic than 2G or 3G.
Why is VoLTE Important?
Previously, 4G LTE networks were primarily used for data. When you made a phone call, your phone would often switch back to 3G or even 2G. VoLTE eliminates the need to switch networks for calls, providing a seamless experience. As older 2G and 3G networks are being phased out ("sunsetted") by many carriers, VoLTE becomes essential for making voice calls on modern smartphones.
Advantages of VoLTE
Here's a summary of the benefits:
- Enhanced Audio Quality: Enjoy clearer and richer sound during calls.
- Quicker Call Connection: Experience faster call setup times.
- Simultaneous Data Usage: Browse the internet and use apps while talking.
- Extended Battery Life: In some cases, VoLTE can improve battery life compared to older technologies.
- Reliance on Modern Networks: Allows you to use voice services even as 2G/3G networks are retired.
