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: 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: 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.

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: A sensor gateway manages wireless communications to sensors and the exchange of data between the sensors and a connection to the Internet. A sensor gateway processor runs the network and wireless stack, automatically picks the same channel as the home access point (AP), and runs sensor software to provide the sensors with low power, wireless support and deep sleep support. The sensor gateway selects same channel as the home AP by following the strongest beacon or by following the home AP service set identifier (SSID), in case more than one strong beacon is present. If the home AP and sensor gateway are placed close by and are on a different channel in 2.4G, there is destructive interference between the two devices. By using same channel on the sensor gateway as that of the home AP, both devices can coexist in same band without destructive interference.

Abstract: Various embodiments disclose systems and methods for employing a Sub1G signal (e.g. a signal in the range of approximately 500 Mhz or 800 mHz) for use with internal and/or external components of various user devices. The Sub1G region may provide a path loss advantage over traditional 2.4 and 5 Ghz systems because of the lower frequency in free-space path loss model. Sub 1G may also present less interference compared to 2.4 GHz (e.g., better QoS for applications such as VOIP, Gaming, etc.). In some of the disclosed embodiments, Sub1G may be employed using current 2.4G or 5G Wireless LAN chipset with RF Up/Down Converters. In some embodiments, the Sub1G approach may be used to create a Long Range Bridge, Long Range Extender, Long Range Client, Long Range Hotspot, etc.

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.
