2.37.1.1.23 Max.-HT-MCS

A specific MCS number denotes a unique combination from the modulation of the individual carriers (BPSK, QPSK, 16QAM, 64QAM), coding rate (i.e. proportion of error correction bits in the raw data) and number of spatial streams. 802.11n uses this term instead of the term "data rate" used in older wireless LAN standards because data rate is no longer an unambiguous description.

Selecting the MCS therefore specifies the minimum and maximum modulation parameters to be used. Within these limits, the appropriate MCS is selected when the connection is established depending on the current conditions and may be adapted during the connection if required. This also defines the maximum attainable data throughput. You can find a list with the values for the different MCS in the reference manual.

The first digit specifies the modulation parameters for one spatial stream, the second digit specifies the modulation parameters for two spatial streams.

Note: In the default setting the station automatically selects the best possible MCS for each stream, based on the conditions of each channel. If interference arises during operation and the channel conditions change, for example due to movement of the transmitter or signal deterioration, the MCS is dynamically adjusted to suit the new conditions.
