Enhance Nstreme throughput even more by providing the option of a sync-based mechanism. Example with 5 clients:
Polling-based
AP Poll -> Client1
Client1 transmit
AP Poll -> Client2
Client2 transmit
AP Poll -> Client3
Client3 transmit
AP Poll -> Client4
Client4 transmit
AP Poll -> Client5
Client5 transmit
Sync-based
AP -> Broadcast Sync and Timeslot assignments
Client1 transmit
Client2 transmit
Client3 transmit
Client4 transmit
Client5 transmit
Wouldn't that be sweet?!?!?
