On the other hand, ADS-B data link standards mainly include the universal access transceiver (UAT) and the 1090 MHz Extended Squitters (1090 ES) [16-17].
 RTCA DO-260A, "Minimum Operational Performance Standard for 1090 MHz Extended Squitter ADS-B and TIS-B," 2002.
Some swear that UAT will go away and 1090ES squitters used by the airlines and high-flying aircraft will ultimately be the standard--or '411111 that government never gives anything away for free (referring to weather)--at least not for long.
This will get you access to all airspace other than Class A, in which a 1090 MHz extended squitter (1090ES) transceiver will be required.

If Fiat emits a wee botty cough then, sure as Italian armies retreat, the rest of Italy gets the squitters

, but a slightly soft, huggy feel and the tyres and suspension come over all smooth.
