FFC :) this is a European product, and since all of the "software" side of things is in your phone this can be available in other regions, and in the worse case scenario you can hack it in yourself. Any radio equipment which is compatible with FRS/GMRS will work with PMR446/KDR444/FREENET and the likes which legally "support" mesh networking and repeaters.

FFC regulations are pretty much bull in regards to many handheld radio frequencies and pretty much force limitations on communication equipment which doesn't require a fee. If you pay for GMRS license you all of a sudden can have repeaters etc. which you can't with FRS even tho they share a frequency range.
