In a 802.11 specification, is it possible that the length of SIFS is shorter than DIFS?
According to IEEE 802.11-1999, the Short Inter-Frame Space (SIFS) is the shortest of the interface spaces. SIFS is used with ACK and CTS frames, and for subsequent frames in multi-fragment data burst. The DCF Inter-Frame Space (DIFS) is used with data and management frames. Figure 49 in clause 9.2.3 of the standard shows the relationship between SIFS and DIFS, with SIFS always being shorter than DIFS.
