WLAN 802.11ac Data Rates
This page of WLAN 802.11ac tutorial covers WLAN 802.11ac data rates.
Following table describes 802.11ac data rates for 20MHz,40MHz,80MHz and 160 MHz bandwidths for various modulation-coding schemes. All the data rates mentioned are with short Guard Interval. MCS 9 is not allowed for 20MHz BW. Also MCS9 is not supported for 6 SS in 80 MHZ BW and for 3 SS in 160 MHz BW. Values mentioned in 20 MHz is for 1 stream, and for 8 stream for 40,80 and 160 MHz. Channel width multiplication factors are 1 for 20MHz BW, 2.1 for 40MHz,4.5 for 80 MHz and 9 for 160 MHz. Values mentioned in 40MHz,80MHz and 160MHz are for 8 Spatial Stream(SS), to obtain for 1 stream one can divide by 8.
| MCS Type | 20 MHz(1 SS) | 40MHz(8 SS) | 80MHz(8 SS) | 160MHz(8 SS) |
|---|---|---|---|---|
| MCS 0 | 7.2 Mbps | 120 Mbps | 260 Mbps | 520 Mbps |
| MCS 1 | 14.4 | 240 | 520 | 1040 |
| MCS 2 | 21.7 | 360 | 780 | 1560 |
| MCS 3 | 28.9 | 480 | 1040 | 2080 |
| MCS 4 | 43.3 | 720 | 1560 | 3120 |
| MCS 5 | 57.8 | 960 | 2080 | 4160 |
| MCS 6 | 65 | 1080 | 2340 | 4680 |
| MCS 7 | 72.2 | 1200 | 2600 | 5200 |
| MCS 8 | 86.7 | 1440 | 3120 | 6240 |
| MCS 9 | n/a | 1600 | 3466.7 | 6933.3 |
