QPSK

 Quadrature Phase Shift Keying.

QPSK is a digital frequency modulation technique used for sending data over networks of several media, including 802.11 wireless.

Doubling the data rate available in BPSK, via improved efficiency in the use of the radio bandwidth, QPSK is used in 802.11b networks of 2Mpbs or greater.
