[i.h]

The OFCOM figures are measured/sampled not  advertised rates
And to  OFCOMs bands…. which are not what any technology/telco works with !
If you look at the data behind it in the interactive report (see p3)
You can see what the numbers are by constituency etc etc .
And how much overbuild…

As more fibre is installed it can only get better
but it is not as bad now as some make out ….
And certainly coverage is better than non PSB broadcasting
And slow speeds are not just a rural phenomenon.

Also, it's measured "properly" - eg some ISPs integrate Samknows or other test suites into their routers, so tests can be performed when the connection is not that busy and crucially is not subject to WiFi coverage/performance/interference.

I have lost track of how many people say their internet is crap - when it's actually because they are using wifi and a poorly optimised setup to boot, eg router at other end of house to where they are. Or they use "mesh" devices which are good for coverage but not great for throughput.
