The FAA has decided that automatic dependent surveillance-broadcast (ADS-B) will use a combination of the 1090-MHz extended squitter surveillance link for air carrier and private/commercial operators of high-performance aircraft, and the universal access transceiver (UAT) surveillance link for the typical general aviation user.

The FAA’s link selection is compatible with a joint strategy currently being coordinated by Eurocontrol and the FAA for implementing ADS-B enabled applications, thus providing for interoperability between the U.S. and Europe.
