A set of audio output devices may be established and configured to output channel specific audio. Once established, the channel configuration may be changed and updated in response to events such as changes to user preference, or the addition or subtraction of audio output devices to the network. In some embodiments, the reconfiguration may be performed on the fly while audio content is being outputted by the audio output devices.

To ensure that multicasts from access points sent in response to periodic beacons reach a variety of listening clients that may have longer sleep intervals than an interval between beacons, this disclosure describes systems, methods, and apparatus for multicasting bursts of frames where a burst number is selected so as to be equal to or greater than a range of common sleep intervals. Further, where multicast frames are re-multicast according to known protocols, the repeated bursts can be offset from the re-multicast start time suggested by the protocol, in order to increase a likelihood that clients with especially long sleep intervals receive the multicast frame.

Multicast packet reception reliability over Wi-Fi

Multiple audio output devices are individually triggered to generate an acoustic identification signal. A controller device can perform a comparison of the acoustic identification signal from each of the multiple audio output devices. The output from one or multiple audio output devices is controlled based on the comparison.

System and method for controlling output of multiple audio output devices

Methods, systems, and devices are described for establishing a virtual communication link including at least a first and second physical link between two devices. A single virtual packet queue of a device may receive one or more data packets to be transmitted via the virtual communication link. The single virtual packet queue may attach a virtual sequence number to each of the one or more data packets and send the one or more data packets to one or more of the first or the second physical link according to the assigned virtual sequence numbers. The one or more packets may then be communicated via the first and/or second physical links according to link specific sequence numbers, such as medium access control (MAC) sequence numbers, assigned to the one or more data packets by the first and/or second physical links.

Link aggregation in wireless local area networks

Systems and methods are disclosed to improve performance of a communications device receiving encrypted communications from multiple sources. The communications device is configured to increase the amount of decryption performed using a hardware-based process as compared to a software-based process by reprogramming the hardware to store a shared security key corresponding to a frame received from a source, allowing the hardware-based process to decrypt subsequent frames from that source.

System and method for hybrid multiple source decryption

A system is disclosed with a first transceiver configured to communicate with a second transceiver. The first transceiver includes a message encoded by a spreading code and a transmitter configured to use beam forming to send the message as a beamformed transmit message to the second transceiver in one of multiple regions repeatedly targeted by the beam forming. The transceivers include a receiver configured to operating without beam forming in receiving to decode the message using the spreading code with a spreading length to compensate for the lack of beam forming. Other embodiments may include an integrated circuit with a processor operating a transmitter and a receiver of the first or the second transceiver. The integrated circuit may act as a central point, a base station and/or an access point communicating with a client, or operate the transceiver as the client, a station or as a cellular phone.

Starting up and synchronizing multiple access points in a wireline communications circuit using transceivers compatible with a wireless communications protocol with an adaptive Time Division Multiple Access scheme for a multi-channel medium with colocated transceivers. Synchronization readiness is asserted and the access points wait for a synchronization start signal's assertion. Methods of operating an access point, its implementation as a chip are further disclosed. An access point assembly including the access points and a synchronization circuit are also disclosed.

Method and apparatus for synchronizing and/or starting access points for adaptive time division multiplexing on a multi-channel wireline medium with colocated transceivers

A wireline communications circuit using transceivers compatible with a wireless communications protocol is disclosed using access points and stations in an adaptive Time Division Multiple Access scheme for a multi-channel medium with colocated transceivers. Methods of operating an access point and a station, their implementations as chips and the implementation of a chip for either the access point or station are further disclosed.
