This field is available only when 802.11n/g or 802.11n/a is
selected as the 802.11 Radio Mode. Select Enable to use
Short GI (Guard Interval). The guard interval is the gap
introduced between data transmission from users in order to
reduce interference. Reducing the GI increases data transfer
rates but also increases interference. Increasing the GI reduces
