VoLTE
VoLTE (Voice over LTE) is a modern technology for making phone calls over 4G LTE networks. Think of it as the next generation of voice calling that replaced older 2G and 3G systems. Just like how we moved from standard TV to HD TV, VoLTE brings HD-quality voice calls to mobile phones. It's a standard way for telephone companies to handle voice calls on their modern networks, providing clearer sound and faster call connection times. When you see this on a resume, it usually means the person has experience working with modern mobile network technologies.
