10.2 OFDMA

Before 802.11ax, Orthogonal Frequency Division Multiplexing (OFDM), a modulation mode is used

for data transmission. OFDM divide the whole channel into several sub-channels (sub-carriers),

and transmit data through these sub-channels, differentiating different data. At some point, data

sent by users will occupy the whole channel. If several users need to use OFDM to send data, they

can only wait in line, wasting channel resources.

802.11ax introduced more efficient data transmission mode, Orthogonal Frequency Division

Multiple Access (OFDMA), a multi-address access technology. It uses OFDM to divide the whole

channel to into several sub-channels (sub-carriers), with user data borne on resource blocks rather

than in the whole channel, thereby allowing parallel user data transmission at the same time. It is

unnecessary for users to wait in line, thus decreasing time delay and improving users’ internet

experience.
