This technique can also be used to produce even higher levels of modulation like 16-QAM where each 4-bit code group generates one of 16 different symbols (Fig. 3). 3.

The fastest QAM now is 4096-QAM, also known as 4K QAM. It can reach peak speeds up to 30Gbps and is used for Wi-Fi 7 (802.11be standards). Some of the best Wi-Fi routers came out just this year to ...

Despite these disadvantages, QAM is the modulation of choice in wireless LANs, cell phones, and other wireless systems especially those using OFDM. Now along comes FSK.

Quadrature amplitude modulation (QAM) uses both the phase and amplitude of a radio frequency signal to represent data bits. WiFi 6 will support 1024-QAM and new modulation and coding schemes that ...
