In Part 1, we learned that QAM works by basically summing two sinusoid waves of the same frequency that are in quadrature. These two sinusoids are called the I, or In-Phase component, and the Q, or Quadrature component. We also learned that as long as we keep the amplitudes of both waves the same, we […]

QAM (pronounced “kwom”) stands for Quadrature Amplitude Modulation. It is a way of modulating, or changing, a waveform, called a carrier wave, to encode some sort of information. In the case of 802.11, this information would be the 1’s and 0’s that make up the data you wish to transmit across the RF (Radio Frequency)
