Abstract: In a repeater, a mechanism checks multiple parameters and makes repeater bandwidth, radio configuration, and ADC clock speed adjustments. multiple repeater parameters are checked and the repeater bandwidth is optimized based upon any of adjusting bandwidth based on best throughput; adjusting bandwidth based on Internet speed; adjusting mapping based on overlapping access points (106); adjusting bandwidth based on the client's range; adjusting ADC clock speed; adjusting transmit (TX) radio setting based on associated clients; adjusting receive (RX) radio setting based on associated clients; client type considerations; and adjusting CPU settings based on clients or backhaul. In embodiments, for example, bandwidth can be adjusted from 80 MHz to 40 MHz to 20 MHz or a smaller bandwidth, e.g. 5 MHz, for an 802.11ac/11ax/11ac device. For an 802.11n/a/b/g/ah device, bandwidth can adjusted using from 40 MHz to 20 MHz to a smaller bandwidth, e.g. 1 MHz, 2 MHz, or 5 MHz.

Abstract: Systems and methods for improving wireless access point communications are provided. Some embodiments contemplate filtering operations such that two or more radios can be used in the 5 GHz or 2.4 GHz band without interfering with each other. Some embodiments employ discrete Low Noise Amplifiers (LNA) and Power Amplifiers (PA) as well as frontend modules. In some examples, filtering may be primarily used on the receiving side to filter out other signals in 5 GHz before they are amplified by an external LNA or LNAs, e.g., as integrated in a WLAN chipset. Filtering may also be performed on the transmit side in some embodiments.

Abstract: 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.

Abstract: A dual band end fed dipole provides at least two distinct operating frequencies, e.g. 2.45 GHz and 5.5 GHz. Properties of the antenna include low cost to manufacture, e.g. ease of automation; minimal manual labor to manufacture, e.g. reliability; dual band operation; broad bandwidth; good feed line isolation; omnidirectional beam pattern; minimal vertical beam squint; small diameter; and high efficiency. Embodiments of the invention provide a dual band end fed dipole with a low band trap on the feed side that requires minimal manual labor to manufacture because the antenna is formed from a single flat sheet of metal and soldering is replaced with crimping. Minimal dielectric loading is also achieved.

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: A method of operating an antenna system for a wireless device is provided for controlling radiation characteristics of the antenna system. The antenna system includes first and second sets of feed points disposed so that first and second radiation pattern are generated by the antenna system when drive currents are provided at the first and second set of feed points, respectively. The second radiation pattern is different from the first radiation pattern. The first and second drive currents are supplied such that a predetermined overall radiation pattern is generated. The predetermined overall radiation pattern is at least in part a combination of the first radiation pattern and the second radiation pattern. The system and method may be directed toward Specific Absorption of Radiation (SAR) mitigation.

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.
