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: 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: Techniques are disclosed for reducing interference, in a network device, among multiple radio circuits operating in a same or similar frequency band and in close physical proximity. In some embodiments, a network device includes a first and a second wireless network circuit. The network circuits operate in a same radio frequency band and are collocated. The second network circuit is assigned a higher priority than the first network circuit. The device further includes a coexistence controller coupled to the network circuits via a communication bus and configured to selectively suppress transmitting operations of the first network circuit during receiving operations of the second network circuit. Among other benefits, the embodiments 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.

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: Techniques are disclosed for reducing power consumption on a power sensitive wireless device, such as for example a digital wireless camera operating on a battery. According to some techniques, power can be reduced when a portable device is in close proximity to the power sensitive wireless device, such as when a person is home and the recording of video on a digital wireless security camera can be disarmed. Some techniques include filtering mechanisms, which reduce unnecessary information being transmitted to the wireless network circuit of the power sensitive wireless device. Other techniques include modifying or adapting IEEE 802.11 standards to achieve power reducing results such as for example reducing the number of times to wake up to receive the beacons. Also, improved synchronization techniques are implemented such as for example improved synchronization accuracy allows reducing the duration of the wake time for receiving the beacons.

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.
