1. A method of controlling a device within a wireless network, comprising:
- sending a Power Save Multi-Poll (PSMP) frame to enable service on a target channel;
waiting for a pre-determined period of time; and
setting a virtual carrier sense on the target channel after expiration of the pre-determined period of time and prior to hopping to a next target channel, wherein the device sends a Broadcast Probe Response (BPR) on the target channel to assist clients scanning for the device to locate the channel in which the device is currently located.

Abstract
Systems and methods for band hopping and power conservation in a wireless network are described. At least one embodiment is directed a method of hopping channels by a device within a wireless network. The method comprises hopping from a first channel to a target channel, resetting a virtual carrier sense after hopping to the target channel to enable service on the target channel, waiting for a pre-determined period of time, and setting a virtual carrier sense on the target channel after expiration of the pre-determined period of time and prior to hopping to a next target channel.

4. A method of controlling a device within a wireless network, comprising:
-
sending a Power Save Multi-Poll (PSMP) frame to enable service on a target channel; waiting for a pre-determined period of time; and setting a virtual carrier sense on the target channel after expiration of the pre-determined period of time and prior to hopping to a next target channel, wherein at least one client remains in sleep mode for a time duration equal to a time duration specified in a frame separate from the PSMP frame. - View Dependent Claims (5, 6, 7, 8, 9, 10)
