  We present here a study of the Infrared properties of Asymptotic Giant Branch
stars (hereafter AGB) based on existing databases, mainly from space-borne
experiments. Preliminary results about C and S stars are discussed, focusing on
the topics for which future Infrared surveys from Antarctica will be crucial.
This kind of surveys will help in making more quantitative our knowledge of the
last evolutionary stages of low mass stars, especially for what concerns
luminosities and mass loss.
