Abstract: Techniques are disclosed for a wireless router or residential gateway to distinguish power-sensitive wireless sensors and provide separate treatments thereto for low power consumption connections. In some embodiments, a network device includes a wireless network circuit, and control circuitry coupled to the network circuit and configured to, upon receipt of a request of connection from a client, identify whether the client is power-sensitive. The network device can further cause, if the client is identified as power-sensitive, the power-sensitive client to connect using a low-power connection while maintaining a regular connection to other regular clients. The low-power connection can be operated on a first channel different from but in a same frequency band as a second channel on which the regular connection is operated.

Abstract: The disclosure is related to a multi-band wireless station, e.g., a wireless access point, that includes more than one wireless radio in the same frequency band. The wireless station operates at multiple frequency bands, e.g., 2.4 GHz and 5 GHz. Further, the wireless station includes multiple radios in the same frequency band. For example, the wireless station can have two radios for the 5 GHz band—one for a low 5 GHz band and another for high 5 GHz band. If the client station is connecting to the 5 GHz band, it can either connect to the first sub-band or the second sub-band of the 5 GHz. The wireless station can decide the sub-band to which a particular client station has to be assigned based on a number of assignment attributes, e.g., client station attributes and the sub-band attributes.

Abstract: Systems and methods for controlling the transmit power and the receive sensitivity of an access point for achieving symmetric link balancing is described. When an access point operates with symmetric link performance, the access point does not inefficiently use available bandwidth for transmitting or re-transmitting to a client station that cannot communicate with the access point. Moreover, the access point does not back off transmissions due to activity of neighboring basic service sets when not needed. The receive sensitivity can be controlled using a hardware attenuator or software commands that adjust a programmable gain in a wireless local area network chipset used by the access point, or it can be controlled using adjustable levels in the software for processing or responding to packets.

Abstract: The disclosure is related to adaptive encoding of video streams from a camera. A camera system includes a camera and a base station connected to each other in a first communication network, which can be a wireless network. When a user requests to view a video from the camera, the base station obtains an encoded video stream from the camera and transmits the encoded video stream to a user device. The base station monitors multiple environmental parameters, such as network parameters, camera parameters, and system parameters of the base station, and instructs the camera to adjust the encoding of the video stream, in an event one or more environmental parameters change.

Abstract: Layer 2 refers to the Data Link layer of the commonly-referenced multilayered communication model, Open Systems Interconnection (OSI). The Data Link layer is concerned with moving data across the physical links in the network. Embodiments of the invention provide a Layer 2 and management modification to provide and maintain an accurate network map. Embodiments of the invention modify Layer 2 functionality to work with a multi-AP system without central management or with central management, and modify management frames to quickly update the network map when the client roams or when topology changes.

Abstract: A dedicated backhaul for whole home coverage variously applies optimization techniques, e.g. using the 5 GHz high band or low band as a dedicated backhaul; using the 2.4 GHz band as backup if the 5 GHz band fails to reach between nodes; using Ethernet when it is better than the 5 GHz and 2.4 GHz bands and it is available; and using a spanning tree protocol or a variant to avoid loops. The dedicated backhaul is used if the received signal strength indication (RSSI) of the dedicated channel is above a threshold. In embodiments, a daisy chain uses probe request contents to communicate hop count and link quality between the nodes by attempting to route directly if link quality is better than a defined threshold. For each extra hop, there must be some percentage gain over smaller hops. If the link is below some threshold, it is not used.
