Air Interface

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:

    Ancient history has an air of antiquity. It should be more modern. It is written as if the specator should be thinking of the backside of the picture on the wall, or as if the author expected that the dead would be his readers, and wished to detail to them their own experience.
    Henry David Thoreau (1817–1862)
