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:
“It is true that the rivers went nosing like swine,
Tugging at banks, until they seemed
Bland belly-sounds in somnolent troughs,
That the air was heavy with the breath of these swine,
The breath of turgid summer, and
Heavy with thunder’s rattapallax....”
—Wallace Stevens (1879–1955)
