The whole U.N. thing is nonsense for several reasons, many of which got discussed just yesterday at https://news.ycombinator.com/item?id=45345514 .

If one is setting up to target the U.N. one does not need this sort of setup to do so. Grand Central Station and the Chrysler Building are just as (in)valid a guess at some purported central target, which one does not have to enclose. The 35 mile radius is ludicrous, and very probably a "telephone game" garbling by PR people of the rough range of SMS to a 2G cell tower given certain conditions. And targetting just a few delegates for scams, with kit that costs thousands of quid per gateway box, is stupidity. The scams thrive on large volumes because they don't net 100% of the marks.

This is a way of having VOIP on one side and what will appear to callees like (doing some simple arithmetic based upon the various photographs) a few hundred (in the site where they're on the floor) to several thousand (in the site where they're on garage shelving along the wall) seemingly legitimate cell phones in multiple locations on the other side. The far more sensible hypotheses are an (overseas) scam support operation, or a dodgy telco operator of some kind.
