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: $\frac{5}{6}$ 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. image image
