Opportunistic key caching" helps us in reducing the time taken for the authentication.Opportunistic Key Caching is where If multiple access points are able to share PMKs among themselves, the station may be able to roam to a new access point it has not visited before and re-use a PMK established with the current access point.


This allows the station to roam quickly to an access point it never authenticated to, without having to perform pre-authentication.
