6000 masts between now and 2023 means a long wait.

Forcing a connection generally won't work as that will be restricting the modem to talk on that freq only for both uplink and downlink. The additional L-Band is for downlink only, so needs all the other freqs to be enabled for uplink.

Also the mast can choose not to let you access a freq.

We'll the rollout has started to reach Aberdeen

This speed test was taken near Dyce, at the new Parkhill junction for those familiar with the area.

6 weeks ago this was sub-5mbps on a B20 carrier, overall just a poor quality connection

Now it's just shy of 200mbps. A remarkable increase.
Hopefully they can roll this out to more locations and a fast pace.

What band combination/CA do you believe caused this 186.76Mbps Down and 14.04Mbps Up compared to the previous result in the same location.

I'm on an Un-Rooted device so can't get the full details, bit Network Cell Info shows the primary as still being B20

So I *think* it's 5MHz of B20 + 20MHz B32 SDL as this would explain the huge 187Mb download but poor 14Mb upload. The cell primary serves an industrial area and today is a bank holiday so I'm probably one of the only users on it. - but I am happy to be proven wrong.

The calculator here https://tools.pedroc.co.uk/4g-speed/ lists 187.5 DL and 18.75 UL as the maximum for 5MHz B20 + 20 MHz B32 SDL assuming 2x2 MIMO and 64 QAM so if my prediction is right, I'm basically using the full capacity of that cell.

Sounds questionable seeing as when I struggle to get good downstream speeds I struggle with upload too.

Just tested right now, 30Mbit down, 1Mbit up. If upstream is contended, there is no bandwidth for the ACK traffic to reach higher download speeds.

But in the scenario I've just described the upload is not contended. I'm getting full performance of the Band 20 carrier

5MHz of B20 at 64QAM gives 37.5 DL & 18.75 UL
20MHz of B32 at 64QAM gives 150 DL & No Upload

That's a total of 187.5 DL and 18.75 UL - which is exactly what I'm seeing. Network Cell Info shows B20 as the primary carrier. If there was B3 or B1 available here, surely it would show as primary above the B20 layer.

Based on your calculations it appears very possible (unless anyone else knows different), would be good to see what the speed says next time you're in the same location on a regular day.

That's likely down to how the people connected to your mast are using their devices. By example I near enough always get c.12-15mb upload even when the download speed is terrible (<5mb) to times when speed is high(ish) >50mb in the middle of the night. Usual download for me is around 25mb, it's very rare for my upload to ever drop below 10mb. This is via band 3 & band 20 CA.

Surprising to see B32 without B3 or B1, but Three's network rebuild is happening fast, so one cell site near you could have new hardware, and not yet fully upgraded. If modes higher than 64QAM appear, faster speeds are also possible.

If you have a Qualcomm cellular radio powered device, then without root, Cellmapper is quite good at showing the bands in use. Other radios are not as informative. Samsung devices have their own engineering status page which shows a lot of detail.
