What is LTE?
LTE stands for Long Term Evolution, and isn’t as much a technology as it is the path followed to achieve 4G speeds. As it stands, most of the time when your phone displays the “4G” symbol in the upper right corner, it doesn’t really mean it. When the ITU-R set the minimum speeds for 4G, they were a bit unreachable, despite the amount of money tech manufacturers put into achieving them. In response, the regulating body decided that LTE, the name given to the technology used in pursuit of those standards, could be labelled as 4G if it provided a substantial improvement over the 3G technology.
Immediately networks began advertising their connections as 4G LTE, a marketing technique that allowed them to claim next-gen connectivity without having to reach the actual required number first; it would be like the U.S. claiming they had landed on the moon because they got pretty close and the spaceship that got them there was a lot better than the previous ship. It’s not entirely trickery though, despite inconsistent speeds depending on location and network, the difference between 3G and 4G is immediately noticeable.
With the introduction of LTE, Voice calls can now be transmitted over a wireless infrastructure without any packet loss or drop call experiences.
