The AIR 3258 radio is specifically designed for European operators and that continents complex spectrum conditions, while the AIR 6419 and AIR 3219 support mid-band spectrum that is more broadly available and in use or forthcoming globally, Tombaz explained. Baseband 6620 and Baseband 6630 provide switching.
