You can increase throughput on the 802.11g, 2.4 GHz radio by enabling short
slot time. Reducing the slot time from the standard 20 microseconds to the 9-
microsecond short slot time decreases the overall backoff, that increases
throughput. Backoff, that is a multiple of the slot time, is the random length of
time that a station waits before sending a packet on the LAN.
Many 802.11g radios support short slot time, but some don't. When you enable
short slot time, the wireless access point uses only the short slot time when all
clients associated to the 802.11g, 2.4 GHz radio support short slot time.
Short slot time is supported only on the 802.11g, 2.4 GHz radio. Short slot time
is disabled by default.
In radio interface mode, enter this command to enable short slot time:
ap(config-if)# short-slot-time
Enter
no short-slot-time
