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 among 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.
Abstract:
Various of the disclosed embodiments provide systems and methods for enabling LTE® and wireless, e.g., ISM band, applications to coexist on a same device or on separate devices in proximity to one another. Some embodiments implement a remediation and/or channel transition process for the wireless devices following detection of LTE®-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 LTE® band. 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:
Introduced here are techniques to provide automated mesh point survey and guided installation for assisting the installation and configuration of a wireless mesh network. Additional implementation techniques are also introduced including, for example, link rate estimation, roaming, and dedicated backhaul link implementation in such wireless mesh network, are also discussed. Among other benefits, this disclosure provides an integral solution where multiple wireless local area network (WLAN) mesh point devices are deployed in a relatively large environment with potential dead spots, such as a home or an office.
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:
A simultaneous client wireless device includes wireless modules configured to perform communication functions of lower MAC (media access control) and PHY (physical) layers for wireless radios operable in multiple wireless bands. The simultaneous client wireless device also includes a communication module configured as an intermediate layer between the lower MAC 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 lower MAC layer and write information to the lower MAC layer of each wireless module, perform communication functions of an upper MAC layer 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:
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.

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.
