5.1. Short Guard Interval
Guard Intervals (GI) are used to ensure that distinct transmissions do not interfere
with one another. The standard symbol guard interval used in 802.11 OFDM is 800ms. To
increase data rate, 802.11n/ac added optional supports for a 400ms guard interval. It is
known as Short Guard Interval. This provides an 11% increase in data rate.
