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: The disclosure is related to a multi-band wireless station, e.g., a wireless access point, that includes more than one wireless radio in the same frequency band. The wireless station operates at multiple frequency bands, e.g., 2.4 GHz and 5 GHz. Further, the wireless station includes multiple radios in the same frequency band. For example, the wireless station can have two radios for the 5 GHz band—one for a low 5 GHz band and another for high 5 GHz band. If the client station is connecting to the 5 GHz band, it can either connect to the first sub-band or the second sub-band of the 5 GHz. The wireless station can decide the sub-band to which a particular client station has to be assigned based on a number of assignment attributes, e.g., client station attributes and the sub-band attributes.

Abstract: A light transmission device includes body that extends between a generally planer lower rim that is configured to collect light from a light source, and an upper rim that is configured to emit the light. The upper rim may be elliptical and emit the light in a generally uninterrupted elliptical light emission pattern, even if the light is transmitted to the lower rim in a linear or other non-elliptical pattern. The light transmission device may be located within a wireless networking device with wireless antennas located between the lower and upper rims of the body.

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.

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: In various aspects, code-based indicia contain secured network access credentials. In some aspects, a computer processor receives user input that specifies secured network access credentials, and the computer processor creates or modifies credentials for establishing a secured network connection. In these aspects, the computer processor generates code-based indicia that contain at least part of the secured network access credentials. In other aspects, a computer processor scans the code-based indicia and extracts the network access credentials. In these aspects, the computer processor employs the network access credentials to establish the secured network connection. In additional aspects, a network router apparatus renders the code-based indicia to an active display. In further aspects, a network router apparatus conditions grant of network access to a device on receipt from the device of an answer to a security question included in the secured network access credentials.

Abstract: Wireless communication under IEEE 802.11 standards utilizing carrier specific interference mitigation where an AP or UE employs an ultra-wideband tuner to evaluate available spectrum between several communication bands. Rather than being constrained to communicate in a single communication band, the AP and UEs may utilize more than one communication band to communicate with one another. In doing so, the AP and UE search across several bands and measure interference on a carrier-by-carrier basis across those bands. Either of the AP and UE may select a cluster of carriers for communication, where the cluster of carriers may comprise 1) contiguous carriers in a single sub-channel, 2) contiguous carriers spanning across more than one sub-channel, 3) discontinuous carriers in a single sub-channel, or 4) discontinuous carriers spanning across more than one sub-channel. The mapping between a cluster and its carriers can he fixed or reconfigurable.
