Abstract: A wireless network device including, in the wireless network device, a Bluetooth device and a wireless local area network device. The Bluetooth device is configured to establish a network of Bluetooth client stations and output a synchronization signal prior to a start of Bluetooth data transmission between the Bluetooth device and the Bluetooth client stations. The synchronization signal indicates the start of the Bluetooth data transmission. The wireless local area network device is configured to establish a network of wireless local area network client stations, receive the synchronization signal from the Bluetooth device, and transmit, a predetermined time subsequent to receiving the synchronization signal, a beacon to the wireless local area network client stations. The beacon instructs the wireless local area network client stations when to begin wireless local area network data transmission.

Abstract: A first device includes a physical-layer device, an adjusting module, and a power module. The physical-layer device transmits, during each of first windows, a request signal from the first device to discover one or more network devices. The first windows occur during a first period of time. The physical-layer device receives responses to the request signal from network devices. Each of the responses is received during a respective one of the first windows. The adjusting module, based on the responses to the request signal, determines whether to adjust lengths of second windows or a number of the second windows to occur during a second period of time. The second period of time occurs subsequent to and is a same length as the first period of time. The power module, during each of the second windows, transitions the first device between being powered ON and being at least partially powered OFF.

Abstract: A client network device includes a physical-layer device, a parameter module, an adjusting module, and a power management module. The physical-layer device, during each client traffic window that occur within a predetermined period, (i) transmits, over a network, a request signal from the client network device to discover other network devices in the network, and (ii) receives, from one or more of the other network devices, corresponding responses to the request signal. The parameter module monitors a first parameter of the client network device. The adjusting module adjusts a second parameter based on the first parameter. The second parameter indicates a number of the client traffic windows to occur within the predetermined period. The power management module transitions the client network device from an active mode to a sleep mode between consecutive ones of the number of the client traffic windows that occur within the predetermined period.
