Wi-Fi transmits information in packets of data, which in turn consist of symbols, each encoded with several bits.
The modulation symbol is a phase and sample code of the signal generated by changing the high frequency carrier frequency, which can then be bit-sequenced or demodulated by the receiver, for example, a 16QAM symbol encodes 4 bits in each symbol. Thus, 4 bits are transmitted with each symbol transmission and decoding. …
