Abstract:
1. An access point for use in a wireless network, the access point comprising: communication interface circuitry that communicatively couples with a packet switched backbone network; access point transceiver circuitry, coupled to the communication interface circuitry, that engages in bidirectional communication with a first client device to couple data to and from the packet switched backbone network, wherein the access point transceiver circuitry transmits to the first client device at a plurality of power levels; and access point processing circuitry, coupled to the access point transceiver circuitry, that selects a first power level of the plurality of power levels for a first transmission by the access point transceiver circuitry, and a second power level of the plurality of power levels for a second transmission by the access point transceiver circuitry, and the first power level is greater than the second power level and wherein the first transmission and the second transmission each contain an address of the first client device wherein the access point processing circuitry selects a third power level of the plurality of power levels for third transmissions by the access point transceiver circuitry to a second client transceiver device and the first power level of the plurality of power levels for fourth transmissions by the access point transceiver circuitry to the second client device, and the second power level is greater that the third power level.
