Some numbers from the real world:

I've been doing a few tests with the Ookla Speedtest app on my Google
Pixel 6 phone when connected to 5G service on one of the Swiss mobile
networks (Sunrise/Yallo).

The download rates are often 250-300Mb/s.  Upload rates are much lower,
typical values are 20Mb/s, but I have seen as low as 5Mb/s even when
downloads are as fast as mentioned.  (OK, 5Mb/s is not too shabby, but
the down/upload discrepancy impresses me.)

The base RTT is relatively low (10-20ms), but can easily grow to
300-1000ms during download and (especially) upload tests.

Sunrise seems to be using the 700, 1400, and 3500MHz bands for 5G.
