A system, device, and method for generating an audio output includes a master computing device and a plurality of client computing devices. Each client computing device includes a microphone to record audio signals. The client computing devices generate audio data based on the audio signals and transmit the audio data to the master computing device. The master computing device generates a final, higher quality audio output as a function of the audio data received from collection of participating the client computing devices.

Systems and methods for implementing a mitigation of overlapping basic service set (OBSS) interference are disclosed. Synchronization of access point (AP) devices may be based upon a transmission synchronization function (TSF) offset between the AP devices. In an implementation, collaboration between the AP devices may include exchanging of beacon schedule frames through a controller, or over the air media access.

Embodiments of a millimeter-wave communication station and method for scheduling association beamforming training (A-BFT) with collision avoidance are generally described herein. In some embodiments an initiating station transmits a transmit sector-sweep frame in each of its antenna sectors and receives a reverse transmit sector-sweep frame from two or more unassociated responding stations. The initiating station transmits a sector-sweep feedback frame to each of the responding stations to indicate whether each responding station is to perform beamforming training in a current beacon interval or a subsequent beacon interval. The sector-sweep feedback frame may indicate an order in which the responding stations are to perform beamforming training in subsequent beacon intervals.

Embodiments of apparatus, packages, computer-implemented methods, systems, devices, and computer-readable media (transitory and non-transitory) are described herein for enabling a first mobile device to control a second mobile device, to enable media content sensed from a perspective of the second mobile device to be consumed using the first mobile device or captured by the second mobile device under control of the first mobile device. In various embodiments, control may include provision of one or more commands to the second mobile device using at least a persistent communication link between the first and second mobile devices. In various embodiments, control may further include receipt of at least a view of media content currently sensed by the second mobile device using a stateless communication protocol. In various embodiments, the first mobile device may control more than one remote mobile devices.

Techniques are disclosed involving media access. For instance, wireless connections may be assigned into one or more groups. The assignments may be based on interference characteristics. Connection(s) within each of these groups may have acceptable interference characteristics with each other. Further, media access may be granted based on these groups. For example, if a device wishes to communicate across one of the connections, access may be granted for concurrent connections among all connections in the corresponding group. The granting of such access may be performed by a centralized controller device, such as an access point.
