VoLTE (Voice over Long-Term Evolution) is a service that allows voice calls to be made over the 4G LTE data network, rather than the older circuit-switched networks used by 2G and 3G.<br \/>\nStatement 2 is incorrect because LTE is a data technology designed for high-speed data transfer, and it can also carry voice traffic (using VoLTE or earlier technologies like CSFB). VoLTE is a specific implementation to carry voice traffic as data packets over the LTE network; it is not a voice-only technology, but rather a method for voice communication *over* a data network. LTE itself provides data connectivity, and voice can be provisioned over it.<br \/>\n<\/section>\n<section id=\"pyq-additional-information\">\nLTE was developed as an upgrade path from GSM\/UMTS technologies, providing increased network capacity and speed. VoLTE leverages the all-IP nature of the LTE network to deliver voice services with potentially higher quality (HD Voice) and faster call setup times, while simultaneously allowing users to access data services during a call. Without VoLTE, voice calls on an LTE network typically require the phone to drop back to a 2G or 3G network (Circuit-Switched Fallback &#8211; CSFB) for the duration of the call.<br \/>\n<\/section>\n","protected":false},"excerpt":{"rendered":"<p>With reference to communication technologies, what is\/are the difference\/differences between LTE (Long-Term Evolution) and VoLTE (Voice over Long-Term Evolution)? 1.
