Abstract: A wireless RF data transmission system has at least one base station transmitting control information on a control channel and high speed data on at least one data channel. At least one subscriber station receives the control information and data channels, adjusting a modulation and/or coding of reception of the data in response to the control information. Preferably, the control information is transmitted using a more robust modulation, such as QPSK, than used to transmit the data, which is preferably transmitted using either 16, 64 or 256 QAM. Additionally, timing or header information for the date may be included on the control channel.

Abstract: A directionally adjustable mounting device is disclosed for use with a small electronic device such as a wireless camera. Also disclosed is a method of using the mounting device. The mounting device has a mounting rod extending from a rotatable bearing. The hearing is biased into frictional contact with a socket by a spring to inhibit movement of the camera relative to the mount housing. The mount is configured to receive an opposing force on the bearing to overcome the spring force and allow the electronic device to be repositioned.

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.
