No, true 5G is a basket of technologies.
Sub-6 is about beam-forming — instead of sending your signal in all directions, it sends only in the direction of your device (and visa-versa which is why antenna design is a larger cost on mobile than before). Now the base station can use the same bandwidth for another device located in a different direction. Over time this will get better and have compounding effects.
And that’s just one item in the basket. mmWave is another. There are several.
