In mobile or wireless communication, the air interface is the radio-based communication link between the mobile station and the active base station. In GSM/UMTS, the various UTRA standards are air interfaces, and are also (but not exclusively) referred to as "access modes".
In the OSI model, the air interface comprises layers 1 and 2 of the mobile communications system, establishing a point-to-point link between the mobile station and the base station.
Famous quotes containing the word air:
“Spread outward. Crack the round dome. Break through.
Have liberty not as the air within a grave
Or down a well. Breathe freedom, oh, my native,
In the space of horizons that neither love nor hate.”
—Wallace Stevens (1879–1955)
