Toda raba for the blog.

5G FBSs are different. When they group-based circle arount the serving cell they offer to be closer neighbour cells and are waiting for the handover request which they answer correctly. They are False Neighbour Cells FNCs.

Its not about MITM of the serving cell.

OK, though the blog post is only Part 1 and only gives an instance of how UE reports can be used to detected one or many FBSs.

Doesn't stop 'network' detection of false base stations. Merely poisoning the UE reports going back to the network for handover requests doesn't prevent detection; even if in theory or practical test run under lab conditions. You are forgetting operator analysis, such as 'deployment'.

Furthermore, how are you overcoming pollution of the EM fields with all these new, extra FBSs promulgated into an area, unless you are saying these FBSs do not use signal strength for detection by genuine UEs to request network to handover to your suggested rogues?

MiTM is not limited to one instance. For instance, even in your own scenario above you identify only one serving cell surrounded by FBSs.

Ok, did you observe FBS in reality or is this a hypothetical approach? Our observations are different.

Whose observations?
Different - how so?
Relating to which specific piece of information?
