5G rubbish upload speed

[Charles2022]

Can anyone explain why the upload speed with a 5G connection is so abysmal? In different locations I typically get 100-600Mbs download speed and 0.5-3Mbs upload speed. If I disable 5G the 4G speed at in the same location is around 60Mbs download and 15-25Mbs upload. I've spoken to 3 support which, unsurprisingly was a complete waste of time, really no idea what I was talking about.

Hello how do you disable the 5g on your router please? I have the same issue I think - I need the faster upload speed so thinking I might be better using 4g...

Because 5G mast using hybrid shared 4G and 5G at the same time. The reason for over 100Meg upload is stand next to the phase 7/8 mast. Further distance away you getting less speed on upload.

By the time in 2030 everyones will get fastest 5G standalone (5G SA) that should improve upload speed.
