ZAN has been using ADS-B for close to 4 years now for radar identification. Though their software was the test bed for ADS-B, but it took years of testing and data/risk analysis to get to that point.
ZNY is using ADS-B in the off shore areas for separation and services when the radar sites are offline..... Some of these areas are single site radar so in the past these airways/sectors would be closed if the radar went offline for any reason. Now they remain open but only for ADS-B equipped flights.
