1. A method of communicating a power management mode of a station on a wireless network, comprising:

  • transmitting by the station a first message on the wireless network, the first message indicating one of at least an active, power save, and ultra-low power power management modes, wherein the indication is communicated in a power management portion of a frame control field of a media access control header, and wherein the power management portion comprises more than one bit;

    operating the station in a power management state in accordance with the indicated power management mode,wherein operating the station in accordance with the active power management mode comprises;

    configuring a first receiver to continuously receive one or more frames from the wireless network, andwherein operating the station in accordance with the power-save power management mode comprises;

    operating the first receiver in two different receiver states,wherein in a first state of the two receiver states, the first receiver is configured to receive at least one frame during a time interval when an access point may transmit at least one frame to the station, andin a second state of the two receiver states, the first receiver is configured to not receive frames, wherein the first receiver is configured to consume less power when operating in the second receiver state than when operating in the first receiver state,wherein operating the station in accordance with the ultra-low power management mode comprises;

    operating the first receiver in the second receiver state, wherein the station transitions to operate in accordance with the active power management mode in response to a second receiver receiving a message from the wireless network,determining one or more time intervals when the second receiver may receive a message,configuring the second receiver to not receive messages during times outside the one or more time intervals, andwherein the second receiver consumes less power when configured not to receive messages than when configured to receive messages.
