WAP (Wirless Application Protocol)

The WAP specifications complement existing wireless standards. For example, the WAP specification does not specify how data should be transmitted over the air interface. Instead, the WAP specification is intended to sit on top of existing bearer channel standards so that any bearer standard can be used with the WAP protocols to implement complete product solutions. It defines a protocol stack that can operate on high latency, low bandwidth networks such as Short Message Service (SMS), or GSM. In addition to being air interface independent, the WAP specification is also independent of any particular device. Instead, it specifies the bare minimum functionality a device must have, and has been designed to accommodate any functionality above that minimum.
