Notes: R8 reaches 42 Mbps by combining 2x2 MIMO and HOM (64QAM) in 5 MHz, or by utilizing HOM (64QAM) and multicarrier in 10 MHz. R9 combines multicarrier and MIMO in 10 MHz to reach 84 Mbps peak rates. Uplink multicarrier doubles the uplink peak data rate to 23 Mbps in 10 MHz in R9. R10 expands multicarrier to 20 MHz to reach 168 Mbps. R11 expands multicarrier to 40MHz to reach 336 Mbps.

1R8 reaches 42 Mbps by combining 2x2 MIMO and HOM (64QAM) in 5
MHz, or by utilizing HOM (64QAM) and multicarrier in 10 MHz. 2R9 combines multicarrier and MIMO in 10 MHz to reach 84 Mbps. Uplink multicarrier doubles uplink peak data rate to 23 Mbps in 10 MHz. 3R10 expands multicarrier to 20 MHz to reach up to168 Mbps. 4R11 expands multicarrier up to 40 MHz to reach 336 Mbps. Uplink MIMO could also double uplink data rates.
