Abstract
Power saving mechanisms can be implemented in an access point to improve power consumption. The access point can be configured to switch from an active power mode to a power save mode in response to not detecting communication activity for at least a predetermined idle time interval. In the power save mode, one or more sleep sub-states and one or more awake sub-states are initiated at the access point. During each awake sub-state, it is determined whether the awake sub-state coincides with a beacon transmission time instant. The access point broadcasts a probe response message if the awake sub-state does not coincide with the beacon transmission time instant. The access point broadcasts a beacon message if the awake sub-state coincides with the beacon transmission time instant.
