Abstract: In a repeater, a mechanism checks multiple parameters and makes repeater bandwidth, radio configuration, and ADC clock speed adjustments. multiple repeater parameters are checked and the repeater bandwidth is optimized based upon any of adjusting bandwidth based on best throughput; adjusting bandwidth based on Internet speed; adjusting mapping based on overlapping access points (106); adjusting bandwidth based on the client's range; adjusting ADC clock speed; adjusting transmit (TX) radio setting based on associated clients; adjusting receive (RX) radio setting based on associated clients; client type considerations; and adjusting CPU settings based on clients or backhaul. In embodiments, for example, bandwidth can be adjusted from 80 MHz to 40 MHz to 20 MHz or a smaller bandwidth, e.g. 5 MHz, for an 802.11ac/11ax/11ac device. For an 802.11n/a/b/g/ah device, bandwidth can adjusted using from 40 MHz to 20 MHz to a smaller bandwidth, e.g. 1 MHz, 2 MHz, or 5 MHz.

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: Systems and methods are described for presenting notifications at a client device based on analysis of content generated by electronic devices in a network-connected security system. The introduced technique can be applied as a filtering process to reduce the number of notifications sent by a network-connected security device to a client device. In an example embodiment, content such as video captured by a video surveillance camera is processed to detect events occurring in a surveilled environment. Notifications are then presented at a user device for events that satisfy some specified criterion.

Abstract: The disclosure is related to adaptive transcoding 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 a video stream from the camera, transcodes the video stream, based on one or more input parameters, to generate a transcoded video stream, and transmits the transcoded video stream to a user device. The base station can transcode the video stream locally, e.g., within the base station, or in a cloud network based on transcoding location factors. Further, the camera system can also determine whether to stream the video to the user directly from the base station or from the cloud network based on streaming location factors.

Abstract: A client device is configured to communicate with an access point over a wireless network, exchanging data with the access point over a selected communication channel. The client device stores an identifier of the selected communication channel. After the wireless connection to the access point has ended, the client device initiates a process to reconnect to the access point over the selected communication channel using the stored identifier.

Abstract: Techniques are disclosed for controlling, in a network device, multiple radio circuits operating in a same or similar frequency band and in close physical proximity. In some embodiments, the radio circuits operate on the same network protocol. The network device can include a coexistence controller coupled to the network circuits. According to some embodiments, the network circuits are each assigned a priority, and the coexistence controller can control operations between the network circuits by selectively adjusting one or more transmission operating parameters of a respective network circuit based on a plurality of operating criteria, which include each network circuit's priority. Among other benefits, the embodiments disclosed herein 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.

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.
