Abstract
A wireless client device is associated with an access point in an association having a value for a listen interval parameter. The wireless client device determines, according to predefined considerations, a different value for the listen interval parameter, and declares the different value for the listen interval parameter in a wireless transmission to the access point. The listen interval parameter specifies a number of beacon intervals that can pass from a time the wireless client device listens for a beacon frame from the access point before the wireless client device listens for a next beacon frame from the access point.
