Abstract
A method, a software product, and an apparatus to determine time offsets to use with a local synchronization clock in a wireless device that can act as a plurality of (virtual) APs, each having a different network identifier. The offsets provide for the wireless device the time to transmit frames that include a broadcast-buffered indication for a particular (virtual) AP identified by a MAC address of a plurality of MAC addresses supported by the wireless device. The broadcast-buffered indication for a particular MAC address indicates that there is broadcast/multicast data buffered in the wireless device. The method is arranged such that the frames containing the broadcast buffered indication for each access point of the wireless device are transmitted by the wireless device at times spread substantially evenly, interleaved with other broadcast frames not containing broadcast buffered indications.
