Abstract: Antenna assemblies are described herein. In particular, described herein are multi-focal-point antenna devices and compact radio frequency (RF) antenna devices. Any of these assemblies may include a primary feed that includes a single patterned emitting surface from which multiple different beams of RF signals are emitted corresponding to different antenna input feeds each communicating with the patterned antenna emitting surface. The antenna assembly is therefore capable of emitting beams in the same direction having different polarizations using a single primary feed.

Abstract: Multi-radio antenna apparatuses and stations for wireless networks including multiple radios coupled to a single transmit/receive antenna, in which the antenna is highly synchronized by an external (e.g., GPS) signal. These multi-radio antenna systems may provide highly resilient links. Synchronization may allow these apparatuses to organically scale the transmission throughput while preventing data loss. The single transmit/receive antenna may have a single dish or a compound (e.g., a single pair of separate transmitting and receiving dishes) and connections for two or more radios.

Abstract: Methods and apparatuses providing a visual metric of the efficiency of a network of devices communicating through a wireless access point (AP). These apparatuses and methods may also determine and display pseudo-dynamic error vector magnitude (EVM) information for a network of wireless stations, including displaying a pseudo-dynamic constellation diagrams using EVM information. These methods and apparatuses may transmit a plurality of sounding packets from each of one or more radio devices different modulation types (e.g., BPSK, QPSK, 16 QAM, 64 QAM, 256 QAM and 1024 QAM), and receiving at least some of the sounding packets at a second radio device (e.g., an access point) and determining EVM information from the received sounding packets, and displaying (or providing for display) a constellation diagram including pseudo-dynamic EVM information that is a constrained approximation of actual EVM information.

Abstract: Polarization-preserving microwave RF filters having multiple resonators that are each operable for different Q factors for setting overall bandwidth. A coaxial dual-polarized waveguide filter may include a cable having a hollow circular body with ends formed by copper plates that each includes at least one iris. The irises may control the energy transfer into and out of the cavity and therefore set the Q factor for the body. The shape of the internal diameter of the body and the irises may provide for reception and propagation of differently polarized signals. Multiple segments may be cascaded in series to effect higher order filtering. Also described are methods of transmitting signals using these filters.

Abstract: Apparatuses and methods for simultaneously operating as a wireless radio and monitoring the local frequency spectrum. For example, described herein are wireless radio devices that use a secondary receiver to monitor frequencies within the operating band and prevent or avoid interferers, including in particular half-IF interferers. The systems, devices, and methods described herein may adjust the intermediate frequency in a superheterodyne receiver to select an intermediate frequency that minimizes interference. In particular, described herein are apparatuses and methods that use a second receiver which is independent of the first receiver and may be connected to the same receiving antenna to monitor the geographically local frequency spectrum and may detect spurious interferers, allowing the primary receiver to adjust the intermediate frequency and avoid spurious interferes.

The method also includes during at least a portion of the boot sequence, transmitting a first wireless packet comprising data indicating a boot status of the network device, wherein the boot status indicates the network device is booting. The method also includes transmitting a second wireless packet comprising data indicating the boot status of the network device, wherein the boot status indicates the network device has finished booting.

Abstract: Apparatuses (e.g., systems and devices) and methods to view otherwise hidden connectivity of networking devices. An electronic device such as a network device connected to a variety of different devices, may be observed through a real-time image onto which information about the connectivity and/or connections may be display to show identity, connectivity state and other information associated with ports of the network device(s). These methods may be implemented on a mobile device used to capture images of the network device and present an overlay of virtual objects on the captured images to a user in real time. The virtual objects may dynamically move or change shape in real time depending on the movement of the mobile device. One or more filtering techniques may be used to stabilize the virtual objects with respect to the captured images.

The device may include a compact array antenna having a high gain configured to operate in, for example, the 5.15 to 5.85 GHz band and/or the 2.40-2.48 GHz band. The antenna emitters may be arranged in a separate plane from a plane containing the antenna feed connecting the emitting elements and also from a ground plane. The antenna array may be contained within a protective weatherproof housing along with the radio control circuitry.

Abstract: One embodiment of the present invention provides a cloud-based video monitoring system comprising a camera and a network video recorder (NVR). During operation, the camera stores in a buffer last predetermined temporal segment of a video. The camera also stores a first video file in a local storage corresponding to an event detected by the camera. This first video file is non-overlapping with a second video file corresponding to the event and this second video file is stored in the NVR. The camera generates a third video file by pre-pending last predetermined temporal segment of a video prior to the event to the first video file and sends the third video file to the NVR.

Abstract: Systems and methods are presented that offer significant improvements in the performance of time division duplex (TDD) systems by utilizing an adaptive synchronous protocol. Conventional TDD systems are limited because data is transmitted during discreet and limited intervals of time, and because TDD transceivers may not simultaneously transmit and receive for reasons of insufficiently separated frequencies and limited receiver selectivity. Typically, TDD systems have significant latency due to the time to change from transmission to reception and the propagation delay time. By synchronizing the master nodes and the one or more remotes and by scheduling the traffic loads between these nodes, remote nodes may begin transmitting before the master node is finished with its transmission, and vice versa. This method reduces latency and improves the frame efficiency. Further, the frame efficiency may improve as the distance from the master node to the remote node increases.
