Abstract: The present disclosure provides systems and methods for generating and transmitting, or applying, a noise profile based on a determined environment a host device is operating in. The host device may receive data from one or more sensors, location information, and/or device information. The sensors may include a pressure, temperature, light, location, or humidity sensor. The location information may include data from a global positioning system and/or connectivity signals, such as multicast DNS and/or Bluetooth broadcast. Device information may include schedule data and/or device state information. The data from one or more sensors, the location information, and/or the device information may be aggregated to determine the environment in which the host device is operating in. Based on the determined environment, a noise profile generator may generate a noise profile. The noise profile may define gains to be applied to audio signals being output to the user.

Abstract: A system and method is provided for improving signal quality in communications among fully wireless systems including a host device in wireless communication with a primary accessory which further wirelessly communicates with a secondary accessory. The host device generates information for use by the primary accessory in determining which channels have interference and should be avoided. The information may include an adaptive frequency hopping (AFH) channel map for communications between the host and the primary device, from which the primary device can infer which frequency bands have interference and generate a second AFH map for communications between the primary accessory and the secondary accessory accordingly. In other examples the information includes the second AFH map generated by the host, for example, based on an out-of-band scan. In further examples, the information includes an indication of channels used by recognized nearby access points.

Abstract: A method of establishing communication between an optical line terminal and an optical network unit within an optical access network includes receiving a signal indication from an optical transceiver of an optical line terminal. The signal indication includes: (i) a loss-of-signal indication indicating non-receipt of an upstream optical signal from the optical network unit; or (ii) a signal-received indication indicating receipt of the upstream optical signal from the optical network unit. The method includes determining whether the signal indication includes the loss-of-signal indication. When the signal indication includes the loss-of-signal indication, the method includes instructing the optical transceiver to cease signal transmission from the optical transceiver to the optical network unit. Moreover, when the signal indication includes the signal-received indication, the method includes instructing the optical transceiver to transmit a downstream optical signal from the optical transceiver to the optical network unit.
