Abstract: Methods, apparatuses, and embodiments related to wireless communication in an environment with electromagnetic interference. In some embodiments, during an initial interconnection setup between a transmitting wireless local area network (WLAN) and a receiving WLAN device, and a first frame or packet is wirelessly transmitted or received by the wireless device. An electromagnetic signal from nearby devices that interferes with wireless transmission is detected. Based on the detection of the wireless transmission interference, the wireless communication parameter is changed to increase communication throughput, and a second frame or packet is wirelessly transmitted or received.

Abstract: Disclosed is a dedicated control channel for a WLAN network. A number of access points are networked together and communicate data necessary to propagate the WLAN over a backhaul channel, however a dedicated radio on each access point is used to communicate control information between the access points. The control information is communicated over a control channel that is different from the client facing channels or bands, and the backhaul channel. In some embodiments, the control channel is sub 1 GHz.

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: 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.

Abstract: Methods, apparatuses, and embodiments related to wireless communication in an environment with electromagnetic interference. In some embodiments, a wireless communication parameter of a wireless device, such as a wireless local area network (WLAN) device, is set to a first value, and a first frame or packet is wirelessly transmitted or received by the wireless device. An electromagnetic signal that interferes with wireless transmission is detected. Based on the detection of the wireless transmission interference, the wireless communication parameter is set to a second value to increase communication throughput, and a second frame or packet is wirelessly transmitted or received.

Abstract: Introduced here are technologies for securely booting a network access device or a satellite device. A network-accessible server system may receive a boot request that includes a boot certificate to identify the network access device. The network-accessible server system may determine that the boot certificate corresponds with a verified boot certificate listed on a boot certificate registry. The network-accessible server system may determine that a geographical location of the network access device and a mobile application executing on an electronic device are within a predetermined range. The network-accessible server system may distribute a digital certificate to the network access device based on determining that the boot certificate corresponds with any verified boot certificate listed on the boot certificate registry and determining that the geographical location of the network access device and the mobile application executing on the electronic device are within the predetermined range.

Abstract: A radio frequency front end module is provided for a high power capability and a high signal band selectivity. The front end module includes an external filter and an integrated circuit coupled with the external filter via two external filter leads. The integrated circuit includes a transmit-receive switch, a power amplifier and a low noise amplifier. The transmit-receive switch alternates between coupling an antenna port to a transmit port and coupling the antenna port to a receive port. The power amplifier amplifies a modulated radio frequency signal. The low noise amplifier amplifies a received radio frequency signal when the antenna port is coupled to the receive port. The external filter can be replaced to adapt to various requirements of signal frequency bands, without the need of modifying the layout of the integrated circuit.

Abstract: Introduced here are techniques to provide automated mesh point survey and guided installation for assisting the installation and configuration of a wireless mesh network. Additional implementation techniques are also introduced including, for example, link rate estimation, roaming, and dedicated backhaul link implementation in such wireless mesh network, are also discussed. Among other benefits, this disclosure provides an integral solution where multiple wireless local area network (WLAN) mesh point devices are deployed in a relatively large environment with potential dead spots, such as a home or an office.
