Orthogonal frequency-division multiplexing (OFDM) 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.

OFDMA is essentially a type of OFDM for multiple users. It allocates in both the time domain and the frequency domain, allowing for multiple users—even those with widely varying use patterns or data loads. By comparison, OFDM can allocate only sequentially. ...
What is OFDM subcarrier? Both OFDM and OFDMA divided a channel into subcarriers through a mathematical function known as aninverse fast Fourier transform(IFFT). The spacing of the subcarriers is orthogonal, so they will not interfere with one another despite the lack of guard bands between them...
Requires a WiFi 6 or newer router: OFDMA is a feature of the WiFi 6 (802.11ax) standard and is not supported by older routers. As such, you may need to purchase a new router to take advantage of it. Higher CPU usage: The increased complexity of OFDMA compared with OFDM means that OF...
