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.

Abstract: Systems and methods for improving wireless access point communications are provided. Some embodiments contemplate filtering operations such that two or more radios can be used in the 5 GHz or 2.4 GHz band without interfering with each other. Some embodiments employ discrete Low Noise Amplifiers (LNA) and Power Amplifiers (PA) as well as frontend modules. In some examples, filtering may be primarily used on the receiving side to filter out other signals in 5 GHz before they are amplified by an external LNA or LNAs, e.g., as integrated in a WLAN chipset. Filtering may also be performed on the transmit side in some embodiments.

Abstract: Various of the disclosed embodiments provide systems and methods for enabling LTE® and wireless, e.g., ISM band, applications to coexist on a same device or on separate devices in proximity to one another. Some embodiments implement a remediation and/or channel transition process for the wireless devices following detection of LTE®-related interference. During remediation, the device may, e.g., adjust the wireless power levels, EDCA backoff times, signal thresholds, etc. In some embodiments, if the remediation actions prove ineffective, the wireless peers may be relocated to a channel further from the interfering LTE® band. The determination to remediate or reallocate may be based on various contextual factors, e.g., the character of the peer devices and the applications being run.

Abstract: Various embodiments are described herein that improve the signal reception and transmission capabilities of an access point by coupling an active antenna assembly to the access point. An active antenna assembly includes an antenna and at least one active component, such as a low-noise amplifier or a power amplifier. The active component can be connected to an antenna circuit board rather than the main circuit board of the access point, which is typically retained within an access point housing. By positioning the active component near the antenna, the active antenna assembly prevents degradation of signals received by the antenna. One or more coaxial cables can be used to connect the active component of the active antenna assembly to the main circuit board of the access point.

Abstract: Techniques are disclosed for reducing interference, in a network device, among multiple radio circuits operating in a same or similar frequency band and in close physical proximity. In some embodiments, a network device includes a first and a second wireless network circuit. The network circuits operate in a same radio frequency band and are collocated. The second network circuit is assigned a higher priority than the first network circuit. The device further includes a coexistence controller coupled to the network circuits via a communication bus and configured to selectively suppress transmitting operations of the first network circuit during receiving operations of the second network circuit. Among other benefits, the embodiments can increase wireless network bandwidth and reduce mobile device power consumption by providing coordination among the radio circuits so that the transmitting and receiving operations are performed in a way that they do not interfere with their respective antennas.
