Patent ID: 8295259

Claim:
A network device comprising: a physical layer device configured to transmit, to a network, a plurality of frames received from a host; and a medium access control device configured to receive a first frame of the plurality of frames from the host, iteratively transmit the first frame to the physical layer device based on a first set of parameters until at least one of (i) the physical layer device receives an acknowledgement signal indicating that the first frame has been successfully transmitted, (ii) a number of transmissions of the first frame is equal to a predetermined count value, or (iii) a predetermined period expires prior to successful transmission of the first frame, wherein the first set of parameters comprises at least one of a first guard interval, a first group of one or more antennas, a first preamble type, or a first bandwidth, and in response to unsuccessful transmission of the first frame based on the first set of parameters, transmit the first frame to the physical layer device based on a second set of parameters, wherein the second set of parameters comprises at least one of a second guard interval, a second group of one or more antennas, a second preamble type, or a second bandwidth.
