Abstract
An access point in a wireless network communicates with multiple mobile stations simultaneously using spatial-division multiple access. The access point transmits to the mobile stations frames that end at different times within a predefined window of time. When the predefined window in time is a short interframe space (SIFS) in an IEEE 802.11 compatible network, the access point will be done transmitting the frames in time to receive acknowledgements from the multiple mobile stations.
