What does the number in the various Quadrature Amplitude Modulation levels, such as 16 in QAM-16 and 64 in QAM-64, indicate? (Choose the single best answer.)
A.
The speed of data transfer,which is four times the number in the QAM level
B.
The channel width, which is stipulated in MHz
C.
The number of target points in the QAM constellation, which are equivalent to amplitude and phase combinations
D.
The number of spatial streams, which is 1/4 the number in the QAM level
QAM Constellations: QAM (Quadrature Amplitude Modulation) uses a constellation diagram where points represent unique combinations of amplitude and phase.
Bits per Symbol: The number in QAM-XX indicates the number of points:
QAM-16: 16 points = 2^4 = 4 bits per symbol
QAM-64: 64 points = 2^6 = 6 bits per symbol
Higher Data Rates: More points in the constellation enable transmitting more bits per symbol, leading to higher data rates at the same bandwidth.
