Abstract
The present invention is a method of reducing latency in transmitting frames of data in a shared access media environment whereby the preamble of the next frame to be transmitted is transmitted while the data portion of the next frame to be transmitted is being retrieved. In another aspect, the early transmission of the preamble of the next frame is started no later than the time it normally takes to fetch and prepare the next frame for transmission less the time it takes to transmit the preamble.
