Isn't the latency mainly determined by congestion / bandwidth saturation on either the radio network or operator's backbone?
IIRC the actual technological latency of a 4G link is just ~2 ms extra; the problem is that you have to share the link with many people, so if the network is overloaded you may get unstable latency. In this regard, anything that increases capacity would automatically help with latency as well.

Yes, but also retransmission that happens at the physical/link layer to mask lossy links from higher layer protocols, such as TCP.

In cities, I routinely get pings of about 40-50ms on LTE. I think it's well past the point of matching fixed broadband in that regard.

Interesting. Here (UK) fixed broadband is much better than that for latency. I ususually see 8-11ms on fixed broadband (DSL-based), yet my ping on 4G is generally more like 40-150ms, with lots of spikes.

Even rural broadband tends to average 30ms pings for idle connections. 4G, like you say, is massively variable.
If 5G could be made closer to WiFi for both mean latency and latency stability it would have a potentially huge impact on broadband access in remote regions (assuming it's easier to deploy 5G there than fiber - which I think is true for most regions).
