64-QAM

A variation on the quadrature amplitude modulation (QAM) signal modulation scheme.

64-QAM yields 64 possible signal combinations, with each symbol representing six bits (26 = 64). The yield of this complex modulation scheme is that the transmission rate is six times the signaling rate. In the United States, 64-QAM is used in digital CATV applications and is specified in the IEEE 802.11a (Wi-Fi5) standard.
