Compare IEEE 802.11 and osi model?

802.11 and OSI are two different things. The 802.11 committee is responsible for setting the wireless standards for wireless communication. The OSI model is not a standard at all, but a theoretical model of how communications work and utilizes many standards in that process.

The 802.11 standards are incorporated in the OSI model, at layer 1 and layer 2 of the model.
