Reliable and deterministic communication protocol
Abstract:
A reliable and deterministic video communication protocol is provided. In one aspect, a method of transmitting data, audio or video frames in a basic service set having a plurality of stations in a wireless local area network transmits a transmit opportunity information element to reserve a transmit opportunity time interval. The method further transmits the data, audio or video frames to a number of the stations in the basic service set during the reserved transmit opportunity time interval. In another aspect, a method of transmitting data, audio or video frames in a basic service set having a plurality of stations in a wireless local area network first transmits protection frames to reserve a time interval, then transmits frames during the reserved time interval or during a non-reserved time interval. In yet another aspect, a method of transmitting data, audio or video frames in a basic service set having a plurality of stations in a wireless local area network utilizes acknowledgement frames from the plurality of stations to acknowledge the transmission. A wireless communication device is also provided.
