摘要： Disclosed is an access point (AP) for a network that includes security features for interacting with devices on the network. The other devices on the network may be other APs, client devices, or a backend configuration server. The access point includes a private key that is used to verify signals to and from (the private key may be different for different functions). In the case of other APs, the private key is used to verify control signals sent between the APs to identify and prevent a hijacked AP from taking control of the network by sending false control signals. In the case of a client device, the client device may use the subject AP's private key to identify that the subject AP is a trusted member of the network that may receive data. In the case of the backend server, the subject AP may verify configuration updates via use of the private key to prevent loading of malicious firmware.

摘要： Disclosed are improved antenna structures, systems, and methods of manufacturing. In an embodiment, low-cost internal 2G/5G antennas have flat metal dipole construction, which can include a stiffener. External embodiments include quad dipole antenna structures, with broadside or corner arrays. Isolated multi-band center or end-fed dipole antennas can include single-sided PCB or metal-only structures, for operation with at least two distinct frequencies, and can provide RF isolation, such as with an RF trap or a Balun system. Embodiments of non-DC path or pass-through dual band antennas feature trap structures, along with discrete or distributed matching, and can provide a DC feed path for LEDs. Low profile and flat vertically polarized omni-directional antennas, such as for operation at 915 MHz, include an open slot driven cavity. Stacked 2G/5G antenna structures provide axial symmetry between quadrants. Improved construction methods and antenna structures include enhanced thin metal components and low cost, crimp-only construction methods.

摘要： Systems and methods are introduced for indoor positioning and tracking of devices and objects using a multi-band wireless networking system. In an embodiment, multiple wireless networking devices are interconnected via a dedicated wireless backhaul to collectively form a single multi-band wireless network providing broad coverage to a client device. The multiple wireless networking devices of the system are coordinated via the dedicated backhaul, for example to manage time synchronization of signals received from the wireless networking devices that are indicative of a position of a client device or object. By coordinating the wireless networking devices via the dedicated backhaul and applying positioning processes to the received signals, a position of the client device or object is determined.

摘要： The disclosed methods and systems use artificial intelligence (AI) and machine learning (ML) technologies to model the usage and interference on each channel. For example, units of the system can measure channel interference regularly over the time of day on all radios. The interference information is communicated to the base unit or a cloud server for pattern analysis. Interference measurements include interference from units within the system as well as interference from nearby devices. The base unit or the cloud server can recognize the pattern of the interference. Further, connected devices have a number of network usage characteristics observed and modeled including bitrate, and network behavior. These characteristics are used to assign channels to connected devices.

摘要： Disclosed is a way to expand the range of Internet of Things devices in a home, office, or structure to the range of a local WiFi network. This is accomplished by generating a network bridge for the devices using machine-to-machine protocols to communicate using the WiFi network backhaul channel. Transmissions in machine-to-machine protocol are tunneled through WiFi communications and extracted by the closest access point. Access points include radios for both WiFi and machine-to-machine protocols.

摘要： 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.

摘要： An embodiment of the invention provides a transmissive passive repeater having two or more antenna arrays, each array comprised of a plurality of antenna elements. Each antenna array has an associated region. An aperture is defined by the antenna arrays with which energy at respective antenna arrays passes between each of the regions. Another embodiment of the invention provides a reflective passive repeater having an aperture. Energy received at the aperture is reflected back from the aperture. The aperture is configured to provide a conformal mapping between two regions as determined by complex coupling by individual antenna elements.

摘要： Various of the disclosed embodiments concern efficiency improvements in wireless products. For example, some embodiments specify profiles for regional and custom-specified operational constraints. The profiles may be retrieved from across a network or stored locally upon the device. The profiles may specify various configuration adjustments that optimize the system's performance. For example, when possible, some embodiments may allow the system to operate at a lower power level and to thereby save energy. Various factors and conditions may be assessed in some embodiments prior to adjusting the existing power configuration.
