Open the CIPO recordAbstract From the Canadian patent
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.
