Patent ID: 7742443

Claim:
A method for transmitting data in a wireless network comprising: transmitting from a station a request-to-send (RTS) frame at a first potency, wherein the first potency is determinable, based at least in part on, a first bit rate and a first radiated power level; receiving at the station a clear-to-send (CTS) frame in response to the RTS frame, wherein the CTS frame has a second potency determinable, based at least in part on, a second bit rate and a second radiated power level; transmitting from the station a data frame in response to the CTS frame, wherein the data frame is transmitted at a third potency determinable, based at least in part on, a third bit rate and a third radiated power level; and receiving at the station an acknowledgment frame as a response to the data frame, wherein the acknowledgment frame has a fourth potency determinable, based at least in part on, a fourth bit rate, a fourth radiated power level, and a frame size of the acknowledgement frame, wherein at least one of the first potency, the second potency, and the fourth potency is greater than the third potency, and wherein the third bit rate is greater than at least one of the first bit rate and the second bit rate.
