One of the biggest advancements due to this kind of tech has actually been throughput for radios. By using more sophisticated / denser encodings, we can scale the same 4G tech to even higher speeds. Think 1gbit/s speeds for mid-market phones. This is effectively enabled due to the smaller node sizes also being more power efficient, which is required for mobile phones.
The advances are less in your face, but still there.
