On a side note (TX vs RX):

When people look at the "speed" of Internet connections, there's often a 
focus on "down" as opposed to "up".

For folk working from home using cloud storage for audio or video 
content that they edit, not having a lot of "up" is an issue.

Here's what to expect around our neck of the woods:

(page 7 and 9)

Now one of the interesting bits about Starlink is that its uplink 
performance is really not that great in comparison to downlink here in 
NZ - pretty much the worst of the current technologies:

This agrees with what I've seen here personally. ADSL in non-fibre areas 
generally now means "miles from the DSLAM", as does VDSL. DSLAM-side 
crosstalk tends to be the limiting factor there.

Non-fibre areas also generally mean "far from the base station". HFC is 
available in only a few select areas here as NZ does not have large 
cable networks.
