OFDM can generate a new symbol (composed of 48 subcarriers) every 4 microseconds . Based on that, it’s possible to signal 250,000 symbol transitions every second on each of the subcarriers.

802.11ax introduces a longer OFDM symbol time of 12.8 μs , which is four times longer than the legacy symbol time of 3.2 μs. Subcarrier spacing is equal to the reciprocal of the symbol time. As a result of the longer symbol time, the subcarrier size and spacing decreases from 312.5 KHz to 78.125 KHz.

Orthogonal frequency division multiplexing (OFDM) takes a digital information signal with bit rate Rb, maps n-bit words on to M = 2n symbols (each symbol being a complex number representing the amplitude and phase of an M-ary modulation scheme ), splits the resulting symbol stream (rate Rs = Rb/n) into N parallel …

Orthogonal frequency-division multiplexing (OFDM) is a multi-carrier modulation system where data is transmitted as a combination of orthogonal narrowband signals known as subcarriers . OFDM builds upon single carrier modulation such as QAM and can transmit at similar data rates.

Orthogonal frequency-division multiplexing is a method of data transmission where a single information stream is split among several closely spaced narrowband subchannel frequencies instead of a single Wideband channel frequency .
