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: Wireless communication under IEEE 802.11 standards utilizing carrier specific interference mitigation where an AP or UE employs an ultra-wideband tuner to evaluate available spectrum between several communication bands. Rather than being constrained to communicate in a single communication band, the AP and UEs may utilize more than one communication band to communicate with one another. In doing so, the AP and UE search across several bands and measure interference on a carrier-by-carrier basis across those bands. Either of the AP and UE may select a cluster of carriers for communication, where the cluster of carriers may comprise 1) contiguous carriers in a single sub-channel, 2) contiguous carriers spanning across more than one sub-channel, 3) discontinuous carriers in a single sub-channel, or 4) discontinuous carriers spanning across more than one sub-channel. The mapping between a cluster and its carriers can be fixed or reconfigurable.

Abstract: A simultaneous client wireless device includes a communication module configured as a layer under a network layer, and configured to receive packets for processing from the network layer and communicate processed packets to the network layer. The communication module is further configured to perform communication functions of an upper MAC (media access control) layer, a lower MAC layer, and a PHY (physical) layer for wireless radios operable in different wireless bands, and manage simultaneous communications over the wireless bands. The communications over the wireless bands can use a local area network protocol.

Abstract: A simultaneous client wireless device includes wireless modules configured to perform communication functions of a PHY (physical) layer for wireless radios operable in different bands. The simultaneous client wireless device also includes a communication module configured as an intermediate layer between the PHY layer of the wireless modules and a network layer. The communication module is configured to use an application programming interface to retrieve information from the PHY layer and write information to the PHY layer of the wireless modules, perform communication functions of upper MAC (media access control) and lower MAC layers for the wireless bands, and manage simultaneous communications over the wireless bands. The communications over the wireless bands can use a local area network protocol.

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: A wireless station implements a technique to reduce the occurrence of collisions between messages in a wireless network by dynamically modify a message interval during a communication session, based on received information indicative of beacon timing. The technique can be implemented by an access point on a wireless local area network to reduce collisions of beacon transmissions. The received information can include information indicative of beacon timing of other wireless stations, difficulty of a wireless station in receiving beacon transmissions, device capabilities, and/or other information.
