Interesting because my router dbm's are far better than yours with a SINR of 20dB, the only difference is you can get Band 1 and are also connected to another cell (getting Carrier Aggregation) to get the + on the end of your 4G.
I can only get connected to my mast on band 3 with no CA, and the best I've seen (this year) is around 70Mbps. Last November I was getting over 100Mbps, after then it started to slide. Its never recovered really since January.
Just done a test on here 9am Friday Morning, 30Mbps at best!
Its so frustrating when I know from experience that Three is capable of so much more. Just wish they're technical department were actually up to the task. (sadly they are not.)
Three's vast differences with new and "very old" mast tech coupled with both good and bad contention across their network obviously has a hell of a lot to be said for............
