1. A device, comprising:
a transmitter configured to transmit data packets to another device via a wireless channel in accordance with a communication protocol that defines an initial energy detection threshold, the initial energy detection threshold representing a radio frequency (RF) energy interference threshold with respect to an interference level in the wireless channel based on a listening operation that is a part of a clear channel assessment (CCA) that identifies transmissions of other transmitters,
wherein the initial energy detection threshold is based upon an initial transmission output power,
wherein interference is introduced in the wireless channel that meets or exceeds the initial energy detection threshold when the device transmits data packets in accordance with the initial transmission output power, which results in an interfering collision with concurrent transmissions from other transmitters; and
processing circuitry configured to, on a per-packet basis prior to the transmitter transmitting each data packet from among the data packets via the wireless channel, (i) selectively adjust the initial transmission output power to an adjusted transmission output power, and (ii) selectively adjust the initial energy detection threshold to an adjusted energy detection threshold that is based upon the adjusted transmission output power, such that the transmitter transmits each data packet from among the data packets via the wireless channel in accordance with either the initial transmission output power or the adjusted transmission output power,
wherein, for a first data packet transmitted via the wireless channel, the initial transmission output power is adjusted to the adjusted transmission output power and the initial energy detection threshold is adjusted to the adjusted energy detection threshold based upon communication parameters associated with the transmission of the first data packet, and
wherein, for a second data packet transmitted via the wireless channel subsequent to the first data packet, the adjusted transmission output power is further adjusted and the adjusted energy detection threshold is further adjusted based upon changes in the communication parameters with respect to when the first data packet was transmitted.
