Wantage is now getting the "There is, at times, heavy usage in this local area" treatment
I was in east Oxford area a couple of days ago and noticed that I was on band 20 from my home mast in Wantage and when in Abingdon I occasionally connected to band 28 from my home mast in Wantage. There are two poles of wonder in Abingdon that are only providing the A34 with "blazing fast 5G" and they've deleted the Abingdon coverage from the map after a few years of proudly listing it as one of the first areas for 5G.
B28 is the devil as far as I'm concerned I can get textbook radio readings at home so on paper it is amazing but the reality is somewhat different. Robbing us of B1 and then not doing any work to make 5G happen means that N1 is not accessed fully owing to required signal level negotiation when accessing 5G ran.
At home I am now using a Zyxel NR5103E and have to keep B28 and 5G off to use B3, B32, B20 so when I'm asleep it's amazing and when I'm awake and want to use it with everyone else it's spotty shall we say. The fibre rush we experienced is now over with Openreach work drying up to almost zero and the signup offers all expiring with no signs of any more work for the foreseeable

.
Still, I one should look for the treasure in the trash and I now get above 5Mbps upload most of the time. Granted, I had to buy a new router but it's better than before!
What I have also noticed is that 13025280 only aggregates B20 intermittently so the majority of the time it's using B3 + B32.
13025286 when I toggle 5G on uses B20 + B32 + N1 and is unusable between 08:00 and 23:00 but while sleeping can deliver 300 down and 60 up. Go back to 4G and this cell also aggregates the uplink using B20 + B32 + B3 with the same timing situation. The aggregated upload and download bandwidth is the same for 5G and 4G. Would be good if 13025280 also aggregated uplink on 4G but hey ho.
