Abstract:
1. A method for transmitting a data packet, the method comprising: prepending to digital contents of the data packet, i) a preamble including a first preamble field having a plurality of repetitions of a sequence, and ii) a second preamble field configured to be used for channel estimation by a receiver; determining, according to a specified communication protocol, a first transmission power level for the data packet; determining, according to the specified communication protocol and the first preamble field, a first unadjusted transmission power level for the first preamble field; determining, according to the specified communication protocol and the second preamble field, a second unadjusted transmission power level for the second preamble field; determining the presence of one or more power-boost characteristics i) of the data packet or ii) of an intended receiving client; transmitting the first preamble field at a first adjusted transmission power level different from the first unadjusted transmission power level if one or more first power-boost characteristics are determined to be present, and transmitting the first preamble field at the first unadjusted transmission power level if the one or more first power-boost characteristics are determined not to be present; transmitting the second preamble field at a second adjusted transmission power level different from the second unadjusted transmission power level if one or more second power-boost characteristics are determined to be present, and transmitting the second preamble field at the second unadjusted transmission power level if the one or more second power-boost characteristics are determined not to be present; and transmitting a remainder of the data packet at the first transmission power level for the data packet.
