    Abstract: Systems, processes, and structures provide near-field transmit power measurement for MIMO wireless devices (DUT), such as for any of product development, product verification, and/or production testing. A test signal, such as comprising a pulse train signal, is provided to a MIMO device under test (DUT), wherein portions of the test signal controllably steered and sequentially transmitted from each of the device antennas, to one or more test antennas that are positioned in close proximity to the MIMO DUT. The near-field power of the received test signals is measured, to quickly and efficiently determine if one or more data streams of the MIMO DUT has a problem.

    Abstract: Systems, processes, and structures allow enhanced near-field testing of the uplink and/or downlink performance of MIMO wireless devices (DUT), such as for any of product development, product verification, and/or production testing. Signal channels may preferably be emulated to test the performance of a device under test (DUT) over a range of simulated distances, within a near-field test environment. An enhanced process provides automated testing of a DUT over a wireless network, e.g. such as but not limited to a WLAN. The enhanced MIMO channel emulator may preferably be operated over a high dynamic range.

    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: 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: 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.
