PNI-NPN

PNI-NPN is the private-network option for enterprises that want dedicated 5G but don't want to build and run a whole standalone system themselves. Instead, a public mobile operator deploys it for them, integrated with the public network — typically carving out dedicated capacity through network slicing and/or dedicated cells on-site, while shared functions ride on the operator's existing infrastructure and spectrum.

The trade against SNPN is control versus convenience. You give up the total isolation and independence of a self-run network, and you take on a dependency on the MNO. In return you get the operator's spectrum, their operations and support, easier wide-area mobility (devices can roam between the private and public network more naturally), and a much lower barrier to standing the thing up. For a lot of enterprises — campuses, logistics sites, businesses that want guaranteed performance without becoming network operators — that's the more realistic path. The "dedicated resources via slicing" part is what keeps it a genuinely private experience rather than just a priority tier on the public network.
