Voice over LTE, or VoLTE, represents a method of transmitting voice data over a 4G LTE network, rather than the older 2G or 3G circuits. Functionally, it enables users to make and receive calls using the high-speed data capabilities of a 4G LTE connection. A practical example is initiating a phone call directly through the phone’s dialer, which utilizes the 4G LTE network to connect and transmit the audio, providing improved audio quality and faster call setup times compared to traditional methods.
The significance of this technology lies in its ability to offer superior voice quality, often described as High-Definition (HD) voice, alongside the faster connection speeds. This contrasts with older technologies which typically provide lower quality audio and longer connection times. Its historical context involves the evolution of mobile networks from circuit-switched technology to packet-switched technology, reflecting the industry’s move toward all-IP networks capable of handling data, voice, and video services efficiently.
