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.

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.

Abstract: A dedicated backhaul for whole home coverage variously applies optimization techniques, e.g. using the 5 GHz high band or low band as a dedicated backhaul; using the 2.4 GHz band as backup if the 5 GHz band fails to reach between nodes; using Ethernet when it is better than the 5 GHz and 2.4 GHz bands and it is available; and using a spanning tree protocol or a variant to avoid loops. The dedicated backhaul is used if the received signal strength indication (RSSI) of the dedicated channel is above a threshold. In embodiments, a daisy chain uses probe request contents to communicate hop count and link quality between the nodes by attempting to route directly if link quality is better than a defined threshold. For each extra hop, there must be some percentage gain over smaller hops. If the link is below some threshold, it is not used.

Abstract: Systems and methods for enabling a WLAN client to communicate simultaneously over more than one band at a time are described, where each client has at least one radio that is operational in each supported band. Load balancing based on traffic requirements optimizes the use of the multiple bands.
