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:
Techniques are disclosed for a wireless router or residential gateway to distinguish power-sensitive wireless sensors and provide separate treatments thereto for low power consumption connections. In some embodiments, a network device includes a wireless network circuit, and control circuitry coupled to the network circuit and configured to, upon receipt of a request of connection from a client, identify whether the client is power-sensitive. The network device can further cause, if the client is identified as power-sensitive, the power-sensitive client to connect using a low-power connection while maintaining a regular connection to other regular clients. The low-power connection can be operated on a first channel different from but in a same frequency band as a second channel on which the regular connection is operated.
Abstract:
The disclosure is related to a multi-band wireless station, e.g., a wireless access point, that includes more than one wireless radio in the same frequency band. The wireless station operates at multiple frequency bands, e.g., 2.4 GHz and 5 GHz. Further, the wireless station includes multiple radios in the same frequency band. For example, the wireless station can have two radios for the 5 GHz band—one for a low 5 GHz band and another for high 5 GHz band. If the client station is connecting to the 5 GHz band, it can either connect to the first sub-band or the second sub-band of the 5 GHz. The wireless station can decide the sub-band to which a particular client station has to be assigned based on a number of assignment attributes, e.g., client station attributes and the sub-band attributes.
Abstract:
A method for selecting signal channel for a wireless networking device is provided. The method collects WLAN and non-WLAN interference information on the candidate channels. The method then determines a weighted grade for each of the candidate channels based on the collected WLAN and non-WLAN interference information. A channel is selected among the candidate channels based on the weighted grades. The method further adjusts WLAN transmit parameter of the wireless networking device based on the collected WLAN and non-WLAN interference information.
Abstract:
Various of the disclosed embodiments concern efficiency improvements in wireless products. For example, some embodiments specify profiles for regional and custom-specified operational constraints. The profiles may be retrieved from across a network or stored locally upon the device. The profiles may specify various configuration adjustments that optimize the system's performance. For example, when possible, some embodiments may allow the system to operate at a lower power level and to thereby save energy. Various factors and conditions may be assessed in some embodiments prior to adjusting the existing power configuration.

Abstract:
Embodiments of the invention provide several antenna designs that exhibit both high bandwidth and efficiency, such as for operation in one or more bands, such as but not limited to operation in 3G, 4G, LTE bands. A first aspect of the invention concerns the form factor of the enhanced antenna; a second aspect of the invention concerns the ease with which the enhanced antenna is manufactured; and a third aspect concerns the superior performance exhibited by the enhanced antenna across one or more bandwidths.
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:
Systems and methods are introduced for video-based channel selection in wireless network connected camera systems. In an illustrative embodiment, a computing system receives data of conditions in a wireless network and data indicative of characteristics of a video stream to be transmitted over the wireless network. The computing system processes the received data to select automatically a channel from a plurality of available channels that can accommodate the transmission of the video stream. The computing system then causes a wireless link, for example between a wireless camera and the wireless access point, to be established on the selected channel or causes an existing wireless link to move from a previous channel to the selected channel
