Using 802.11n (HT) as the PHY, configure as follows: Modulation: 64-QAM Data Bandwidth: 20MHz Number of Spatial Streams: 4 According to the 802.11n (HT) modulation table, we have: Number of Data Subcarriers: 52 Number of Coded Bits per Subcarrier per Stream: 6 Coding: 5/6 OFDM Symbol Duration: 3.2 µs Guard Interval Duration: 0.8 µs Using these parameters and the formula, the calculated data rate is 260 Mbps, which matches the displayed result.

Using 802.11n (HT) as the PHY, configure as follows:
Modulation: 64-QAM
Data Bandwidth: 20MHz
Number of Spatial Streams: 4
According to the 802.11n (HT) modulation table, we have:
Number of Data Subcarriers: 52$\frac{5}{6}$
Number of Coded Bits per Subcarrier per Stream: 6
Coding:
OFDM Symbol Duration: 3.2 µs
Guard Interval Duration: 0.8 µs
Using these parameters and the formula, the calculated data rate is 260 Mbps, which matches the displayed result.
