5G Network density over N3 and N6

Hi Everyone,

I am trying to get a grasp of how many 5G UE's can a gNodeB support per cell.

I am researching GTP Firewall solutions and hardware accelerated UPF and I cannot find a straight answer from datasheets. I need to understand what is the current cell density in macro and small-cell deployments for 5G-NR (3.5-4GHz)

Specifically I need to understand how many concurrent GTP tunnels are inside the n3/n6 interfaces.

Thanks in advance.
