SNR Required for Each MCS
The table below shows the SNR required for each MCS index as well as the modulation, coding and data rate per
stream based on channel width in MHz. Note that each channel uses up to two streams.
Examples:
2 x 80 MHz channels operating at MCS 8 with 4 streams would yield 1560 Mbps (390 Mbps * 4 streams).
●
1 x 40 MHz channel operating at MCS 6 with 2 streams would yield 270 Mbps (135 Mbps * 2 streams).
