+1  Q: 

why do all compatible 802.11 standards use the same value of SIFS/DIFS?

802.11 standards define SIFS/DIFS value. Why do they use the same values? and if they use different values in the same network, what would happen?

A: 

The reason they are the same between different standards is for backward compatibility between 802.11g and 802.11b. If they are different, then simply backward compatibility is forfeited.
