Inside Wireless: QAM modulation (Quadrature Amplitude Modulation)
Most of the radios Wireless Internet Service Providers use in their networks utilize Quadrature Amplitude Modulation (QAM). How does it work? Why higher MCS rates need higher signal to noise ratio? Find out in this Inside Wireless episode! Learn more: https://rfelements.com/
QAM stands for Quadrature Amplitude Modulation and it’s the most common modulation modern digital radios use to encode information onto RF waves.
The RF waves have three main properties we can control to encode information on them. Amplitude, frequency, and phase. Digital communication systems work with ones and zeros which are easy to encode.
With Amplitude modulation, a simple on/off switch is enough to encode 1 and 0. With frequency modulation, signals with two different frequencies do the job. With phase modul...

Quadrature Amplitude Modlation (QAM): Explained
Quadrature Amplitude Modulation (QAM) is used to send large amounts of data by modulating the amplitude of two independent quadrature carrier waves onto a higher frequency carrier wave.
Since these carrier waves are in quadrature they can be coherently demodulated to obtain the independent amplitudes.
QAM allows for extremely large data rates across relatively small bandwiths.

Inside Wireless: QAM modulation II - The Modulator
QAM modulation is vital to most of modern digital RF radios out there. But what exactly the modulator does? We explain in this episode of Inside Wireless! Learn more: https://rfelements.com/
Modulation is a process of encoding the digital data - 1 and 0s - onto an RF wave that is more suitable for wireless transmission. The QAM modulator is the circuit inside the radio that takes care of this.
If not sure about the basics of QAM modulation, check our previous video: https://youtu.be/IbUflaeJcU8
The basic idea is that the incoming data stream is divided into two branches. The length of the 'symbol', or, the amount of 1s and 0s processed in parallel determines the depth of the modulation. The higher the number, the more data we transfer during one transmission.
The RF carrier signal is...

QAM stands for Quadrature Amplitude Modulation and it’s the most common modulation modern digital radios use to encode information onto RF waves.
The RF waves have three main properties we can control to encode information on them. Amplitude, frequency, and phase. Digital communication systems work with ones and zeros which are easy to encode.
With Amplitude modulation, a simple on/off switch is enough to encode 1 and 0. With frequency modulation, signals with two different frequencies do the job. With phase modulation, shifting the signal by 180 degree does the trick.
QAM modulation is a combination of amplitude and phase modulation. At the input of QAM modulator is digital data processed by symbols, or groups of bits at once. At the other input of the modulator is the RF carrier signal. These input signals are combined in the modulator which controls the Amplitude and the Phase of the resulting output signal, which let’s us encode more information onto the signal compared to any modulation alone.
The length of the symbol determines the QAM modulation depth and maximum number of symbols. The symbols can be mapped into so called constellation diagram which helps us easily understand the QAM modulation - check the video to see the constellation diagram.
With growing QAM depth, we pack more information into the same signal but also increase the demand on acceptable SNR level - the deeper the modulation, the higher required SNR.
Considering the 802.11ac standard and 20 MHz channel, we need at least 5 dB SNR for QPSK, 11 dB SNR for 16QAM, 18 dB SNR for 64 QAM and so on.
For practical use, the MCS rates of the 802.11ac standard combine information about the Modulation depth, number of spatial channels and coding rate - which says what part of the transferred data is user data.

QAM modulation is vital to most of modern digital RF radios out there. But what exactly the modulator does? We explain in this episode of Inside Wireless! Learn more: https://rfelements.com/
Modulation is a process of encoding the digital data - 1 and 0s - onto an RF wave that is more suitable for wireless transmission. The QAM modulator is the circuit inside the radio that takes care of this.
If not sure about the basics of QAM modulation, check our previous video: https://youtu.be/IbUflaeJcU8
The basic idea is that the incoming data stream is divided into two branches. The length of the 'symbol', or, the amount of 1s and 0s processed in parallel determines the depth of the modulation. The higher the number, the more data we transfer during one transmission.
The RF carrier signal is brought to both of these branches and multiplied by the amplitude (strength) determined by the input data stream. One branch is called I (in-phase) and the other Q (quadrature). The quadrature means that the I and Q waves are shifted by 90 degrees with respect to each other. After that, the I and Q signals are added to produce the output RF signal.
The increasing data density with growing length of the input symbol is easily seen on an IQ diagram showing each unique symbol the modulator can produce. The higher the data density in the same space, the higher the SNR of the signal needed for successful data transfer - check out this video for detailed explanation: https://youtu.be/1TYW7T6X2_k
Spectral efficiency is a measure of increasing data transfer efficiency with growing QAM depth.
The distances at which the typical WISP radio is capable of working at highest MCS rates are very short - this is again connected to the SNR requirement of the signal and the output amplifier linearity - check our video on this topic: https://youtu.be/lPDNG1mjeq8
