11b slot =20 mjus but sifs = 10mjus
11g slot = 9 or 20 mjus but sifs =10mjus
11a slot=9 mjus but sifs = 16 mjus
为什么这么改,sifs比slot还短?
谢谢

SIFS is effectively 16us in 11a/g/n (including signal extension in 11g/n).
ACK is sent back after DATA+SIFS. SIFS is shorter than slot so that
collision on ACK is avoided as much as possible.
