Abstract
An access point is to handle received broadcast or multicast traffic as multiple instances of unicast traffic, where each instance is destined for a corresponding wireless client device associated with the access point. A client device may adjust its listen interval parameter according to predefined considerations, for example a charge level of a battery to power the client device and an expected usage model for the device. A client device may initiate a reassociation request to inform the access point of its adjusted listen interval parameter.
