PHY-Layer Data Rates
Because the physical layer of WiMAX is quite flexible, data rate performance varies based
on the operating parameters. Parameters that have a significant impact on the physicallayer
data rate are channel bandwidth and the modulation and coding scheme used. Other
parameters, such as number of sub-channels, OFDM guard time, and oversampling rate,
also have an impact.
Following is the PHY-layer data rate at various channel bandwidths, as well as modulation
and coding schemes.
