Abstract: 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.

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 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.

Abstract: Techniques are disclosed for a wireless router or residential gateway to distinguish power-sensitive wireless sensors and provide separate treatments thereto for low power consumption connections. In some embodiments, a network device includes a wireless network circuit, and control circuitry coupled to the network circuit and configured to, upon receipt of a request of connection from a client, identify whether the client is power-sensitive. The network device can further cause, if the client is identified as power-sensitive, the power-sensitive client to connect using a low-power connection while maintaining a regular connection to other regular clients. The low-power connection can be operated on a first channel different from but in a same frequency band as a second channel on which the regular connection is operated.

Abstract: A simultaneous client wireless device includes a communication module configured as a layer under a network layer, and configured to receive packets for processing from the network layer and communicate processed packets to the network layer. The communication module is further configured to perform communication functions of an upper MAC (media access control) layer, a lower MAC layer, and a PHY (physical) layer for wireless radios operable in different wireless bands, and manage simultaneous communications over the wireless bands. The communications over the wireless bands can use a local area network protocol.

Abstract: A simultaneous client wireless device includes wireless modules configured to perform communication functions of a PHY (physical) layer for wireless radios operable in different bands. The simultaneous client wireless device also includes a communication module configured as an intermediate layer between the PHY layer of the wireless modules and a network layer. The communication module is configured to use an application programming interface to retrieve information from the PHY layer and write information to the PHY layer of the wireless modules, perform communication functions of upper MAC (media access control) and lower MAC layers for the wireless bands, and manage simultaneous communications over the wireless bands. The communications over the wireless bands can use a local area network protocol.

Abstract: A wireless station implements a technique to reduce the occurrence of collisions between messages in a wireless network by dynamically modify a message interval during a communication session, based on received information indicative of beacon timing. The technique can be implemented by an access point on a wireless local area network to reduce collisions of beacon transmissions. The received information can include information indicative of beacon timing of other wireless stations, difficulty of a wireless station in receiving beacon transmissions, device capabilities, and/or other information.

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.

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.
