Abstract:
A system-on-chip including a host interface module configured to interface the system-on-chip to a host processor of a wireless device and to communicate with the host processor of the wireless device via a bus. The bus uses an application programming interface of the system-on-chip. The host processor uses the application programming interface to configure a power save mode of the system-on-chip. A power management module operated the system-on-chip in the power save mode without performing a handshake with the host processor via the bus in response to the host processor stopping communication with the system-on-chip. The handshake includes (i) sending a request to enter the power save mode to the host processor via the bus and (ii) receiving an acknowledgement of the request from the host processor via the bus.
Abstract:
An infrastructure and ad-hoc node device is described. In embodiments, a node device includes an ad-hoc interface for data communications via an ad-hoc network that includes peer devices of a first basic service set (BSS). The node device also includes an infrastructure interface for additional data communications via an infrastructure network of nodes that communicate via an access point of a second basic service set. A power save service can optimize a power save mode of the node device by minimizing a device communication mode during which the data communications and the additional data communications are received over a shared communication channel, or are received over different communication channels.
Abstract:
An access point configured to be implemented in a wireless network, the access point including a beacon module and a transmit module. The access point is configured to communicate with one or more client stations in the wireless network. The beacon module is configured to generate (i) a first beacon and (ii) a second beacon, wherein the first beacon is shorter in duration than the second beacon. The transmit module is configured to periodically transmit, to the one or more client stations in the wireless network, each of the first beacon and the second beacon. Each time the first beacon and the second beacon are transmitted by the transmit module, the first beacon is transmitted prior to the second beacon.
Abstract:
The present specification describes techniques and apparatuses that enable power conservation in a wireless network. In some cases these techniques and apparatuses enable power conservation during a discovery phase and for a wireless network subject to a government mandate requiring a device of the network to passively search for radar transmission prior to establishing communication with another device of the network.

The device further includes a second processing unit configured to control a first wireless network including the device and the first station to operate the embedded access point as an access point for the first wireless network, and operate the embedded access point as a station in a second wireless network that includes the embedded access point and the separate access point. The separate access point provides access point functionality for the second wireless network, and the embedded access point is configured to be powered via the interface.
Abstract:
A networking device includes a transmitting device and a host circuit. The transmitting device is configured to store packets in a transmit queue. The transmitting device is further configured to transmit the packets from the transmit queue in accordance with a local area network protocol. The transmitting device is further configured to selectively generate a signal indicating an available capacity of the transmit queue. The host circuit is configured to receive input packets for transmission by the transmitting device. The host circuit is further configured to, in response to an aggregation mode being enabled, (i) generate an aggregate packet using ones of the received input packets, and (ii) in response to the signal, provide the aggregate packet to the transmitting device for transmission. The host circuit is further configured to, in response to the aggregation mode being disabled, individually provide the received input packets to the transmitting device for transmission.
Abstract:
A method of controlling transmission of data units in a network node includes receiving a current fragment of a data unit at the network node, the data unit having been fragmented into an ordered sequence of fragments prior to the current fragment being received at the network node. The method also includes determining, at the network node, whether the current fragment is expected. Determining whether the current fragment is expected includes determining a position of the current fragment within the ordered sequence of fragments. The method also includes, in response to determining that the current fragment is expected based on the determined position of the current fragment within the ordered sequence of fragments, transmitting the current fragment via a network link.
Abstract:
Selection between first and second communication channels of differing bandwidths for communication between communication devices may be chosen by a method, an apparatus, or a computer-readable medium wherein the first channel is employed as a communication channel, a determination is made whether a criterion associated with the communication channel is met, and, if the criterion associated with the communication channel is met, an evaluation of the second channel is performed and one of the first and second channels is chosen to subsequently employ as the communication channel based on the evaluation of the second channel.
Abstract:
A system and method are disclosed for decreasing the amount of power consumed by a wireless signal receiver in a wireless device. Received data is communicated from the receiver to a play-out buffer in communication with a media play-out device. The level of data in the play-out buffer increases when received data is written to the buffer, and the level of data decreases when data is read from the buffer. If the level of data is above a first watermark level, the receiver is transitioned to a sleep mode while data is read from the buffer. When the level of data in the buffer falls below a second watermark level, the receiver is transitioned back to an active mode to receive data. The device communicates status messages (whether the receiver is asleep or active) to the transmitting device so that the transmitting device stops transmitting data when the receiver is in sleep mode, and transmits data when the receiver is in the active mode.
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.
