LTE - definition
LTE (Long Term Evolution) is a standard for wireless broadband communication for mobile devices based on GSM or EDGE and UMTS or HSPA standards. It improved those standards' capacity and speed using a different type of radio interface. LTE is also known as 3.96G or said as “4G LTE”. Also, it needed to be mentioned that it is slower than “True 4G” but for sure faster than 3G. VoLTE is a feature of the 4G network which surprisingly improves the audio quality of regular phone calls made over a standard voice network. VoLTE also allows users to make six-way (6-way) conference call uninterruptedly.
