But it is changing transmission technique si the technique of simultaneous data manipulation, Wi-Fi 5(802.11ac)
uses a technique called Quadrature Amplitude Modulation(QAM), and the capacity is 512-QAM.
In QAM, an in-phase signal(or I,
with one example being a cosine waveform) and a Quadrature phase signal(or Q,
with an example being a sine wave) are amplitude modulated with a finite number of amplitudes and then summed.
