Abstract: In response to determining that a Bluetooth inquiry phase or the Bluetooth paging phase will begin, a power save indicator signal is sent from a first communication device to a second communication device prior to a start of the Bluetooth inquiry phase or the Bluetooth paging phase. A gap between a first Bluetooth communication slot and a second Bluetooth communication slot is determined, and a time period within the gap is determined, where an end of the time period occurs at a defined amount of time prior to a start of the second Bluetooth communication slot. During the time period, one or more power save poll messages are sent from the first communication device to the second communication device, each first power save poll message prompting the second communication device to transmit a respective first WLAN packet to the first communication device.

Abstract: A network interface including a radio frequency (RF) system and a media access controller (MAC). The RF system wirelessly communicates with an access point (AP). The MAC includes client modules. A first client module transmits a first signal from a host to the AP via the RF system in accordance with a first wireless communication standard. A second client module transmits a second signal from the host to the AP via the RF system in accordance with a second wireless communication standard. The second client module determines a quality level of the second signal transmitted from the second client module to the AP, and based on the quality level of the second signal, hands off access to the RF system from the second client module to the first client module to allow the first client module to transmit the first signal to the AP via the RF system.

Abstract: A device previously configured as a registrar and that has established an independent ad-hoc network is automatically discovered by another device also previously configured as a registrar. To form an ad-hoc wireless network between these two devices, each device periodically enters a scanning mode to scan for and intercept beacons transmitted by the other device. Upon such interception, one of the devices becomes an enrollee in accordance with a predefined condition and in response to a user selected option. Subsequently, the enrollee modifies its beacons to include an attribute, such as the MAC address, associated with the other device. After intercepting the modified beacon, the remaining registrar prompts it user to decide whether to allow the enrollee to join the registrar's network. If the user responds affirmatively, a handshake is performed between the two devices and a subsequent attempt is made by the enrollee to join the registrar's network.

Abstract: Techniques for establishing a dynamic ad-hoc wireless network are disclosed. A node transitions between wake and sleep modes during periods defined as beacon intervals. Before a network connection is established and while it is awake, the node transmits network connection request and also listens for network activity. If a beacon or response message is not detected while the node is listening, the node enters sleep mode and thereby conserves power. The node optionally changes the duration of its detection period and/or the time at which it listens for network activity relative to the start of each beacon interval. Information elements are optionally included with transmitted beacons or response messages.

Abstract: A first communication device listens, during advertise states of the first communication device, for probe requests from one or more second communication devices on a first channel included in a plurality of channels. At least some respective lengths of the advertise states of the first communication device are different. When one or more first probe requests are received from the one or more second communication devices during the advertise states of the first communication device, the first communication device transmits one or more first probe responses responsive to the one or more first probe requests. The first communication device transmits second probe requests on respective second channels during respective search states of the first communication device, and listens, during the search states, for one or more second probe responses on the second channels.

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.
