Enable or disable the short guard interval.
Put simply, the guard interval reduces the signal distortion caused by intersymbol interference (ISI) when using signal multiplexing (OFDM). The option reduces the transmission pause between two signals from 0.8 µs (default) to 0.4 µs (short guard interval). This increases the effective time available for data transmission and thus the data throughput. However, the wireless LAN system becomes more liable to disruption that can be caused by interference between two consecutive signals.
