Abstract
To ensure that multicasts from access points sent in response to periodic beacons reach a variety of listening clients that may have longer sleep intervals than an interval between beacons, this disclosure describes systems, methods, and apparatus for multicasting bursts of frames where a burst number is selected so as to be equal to or greater than a range of common sleep intervals. Further, where multicast frames are re-multicast according to known protocols, the repeated bursts can be offset from the re-multicast start time suggested by the protocol, in order to increase a likelihood that clients with especially long sleep intervals receive the multicast frame.
