    Abstract: Methods, apparatuses, and embodiments related to a technique for managing interference of communication of a wireless network in a multi-band wireless networking system. In an example wireless network with multiple wireless networking devices and one or more client devices, communications between the wireless networking devices occurs via a backhaul channel, and communication between the client(s) and the wireless networking devices occurs via a fronthaul channel. In response to detection of electromagnetic interference, a wireless networking device attempts to manage the interference, such as by adjusting a parameter associated with circuitry associated with a radio of the wireless networking device, or by other disclosed techniques.

    Abstract: Disclosed are methods and systems for interactive dynamic interference testing of wireless environments, which can emulate wireless traffic for multiple homes, apartments and offices. The emulated wireless environment can emulate a wide variety of 802.11 traffic, as well as other types of traffic. Some embodiments can also control any of the power level of interference, as well as the attenuation between devices, such as between access points and clients. The system and method can be used to monitor the performance of a device under test (DUT) under one or more interference conditions, and can be used to evaluate and modify the dynamic behavior of the DUT and other devices under different operating scenarios.

    Abstract: Various of the disclosed embodiments improve the operations of a combined access point/Cable modem. Though the access point component and the Cable modem component may perform operations in different spectrums, harmonics in the Cable spectrum may interfere with operations, e.g., in the 2.4 GHz and 5 GHz range, of the access point. Some embodiments implement a remediation and/or channel transition process for the access point following detection of Cable-related interference. During remediation, the device may, e.g., adjust the wireless power levels, EDCA backoff times, signal thresholds, etc. In some embodiments, if the remediation actions prove ineffective, the wireless peers may be relocated to a channel further from the interfering Cable harmonics. The determination to remediate or reallocate may be based on various contextual factors, e.g., the character of the peer devices and the applications being run.

    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: Systems and methods for improving wireless access point communications are provided. Some embodiments contemplate filtering operations such that two or more radios can be used in the 5 GHz or 2.4 GHz band without interfering with each other. Some embodiments employ discrete Low Noise Amplifiers (LNA) and Power Amplifiers (PA) as well as frontend modules. In some examples, filtering may be primarily used on the receiving side to filter out other signals in 5 GHz before they are amplified by an external LNA or LNAs, e.g., as integrated in a WLAN chipset. Filtering may also be performed on the transmit side in some embodiments.

    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 translation: 传感器网关管理传感器的无线通信和传感器之间的数据交换以及与因特网的连接。 传感器网关处理器运行网络和无线堆栈，自动选择与家庭接入点（AP）相同的通道，并运行传感器软件，为传感器提供低功率，无线支持和深度睡眠支持。 传感器网关在存在多于一个强信标的情况下，通过跟随最强信标或跟随归属AP服务集标识符（SSID）来选择与归属AP相同的信道。 如果家庭AP和传感器网关放置在2.4G附近并且位于不同的信道上，则两个设备之间存在破坏性的干扰。 通过在传感器网关上使用与家庭AP相同的信道，两个设备可以共存在相同的频带中，而不会产生相互破坏的干扰。

    Abstract: Techniques are disclosed for controlling, in a network device, multiple radio circuits operating in a same or similar frequency band and in close physical proximity. In some embodiments, the radio circuits operate on the same network protocol. The network device can include a coexistence controller coupled to the network circuits. According to some embodiments, the network circuits are each assigned a priority, and the coexistence controller can control operations between the network circuits by selectively adjusting one or more transmission operating parameters of a respective network circuit based on a plurality of operating criteria, which include each network circuit's priority. Among other benefits, the embodiments disclosed herein can increase wireless network bandwidth and reduce mobile device power consumption by providing coordination among the radio circuits so that the transmitting and receiving operations are performed in a way that they do not interfere with their respective antennas.
