Abstract
An access point is to transmit delivery traffic indication messages at different periods of beacon frames for different wireless client devices associated with the access point. A client device may store an indication of a preferred period of beacon frames at which to listen to delivery traffic indication messages when in power save mode. The client device may adjust its preferred period according to predefined considerations, for example a charge level of a battery to power the client device and/or an expected usage model for the client device. A client device may negotiate its preferred period with the access point.
