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.
To make matters more confusing, you’ll also likely come across LTE-A at some point. This stands for Long Term Evolution Advanced, and it takes us a step closer to proper 4G. It offers faster speeds and greater stability than normal LTE. It’s also backward compatible and works by aggregating channels, so instead of connecting to the strongest signal in your vicinity, you can download data from multiple sources at the same time.
