Patent number: 9960874Abstract: Embodiments of the present invention provide techniques for managing interference across multiple transceivers in an access point in a network environment. A wireless networking system can include various access points. These access points may each include multiple transceivers. However, with multiple transceivers in close proximity, signals transmitted by one transceiver may interfere with another transceiver through crosstalk, adjacent channel interference, or other form of interference. Each access point may include an interference manager which can use an interference model to modify a signal transmitted by one transceiver to be used to cancel corresponding interference caused in a second transceiver. Interference can be modeled prior to deployment and/or at deployment using a series of test signals transmitted by one transceiver while the corresponding interference is monitored on a second transceiver.Type: GrantFiled: July 20, 2016Date of Patent: May 1, 2018Assignee: Zinwave, Ltd.Inventors: Matthew P. Pasulka, Andrew Robert Bell

Publication number: 20180027430Abstract: Embodiments of the present invention provide techniques for locating network components in a distributed antenna system. A DAS can include various antennas located within a deployment environment. The DAS may include a centralized hub that may interface with various broadband sources and manage access to the broadband sources for devices that connect to the DAS. In some embodiments, the centralized hub may communicate with one or more remote units that convert signals received from the centralized hub to be communicated using one of the distributed antennas. Components of the DAS may be associated with a beacon. The beacon can be configured to determine that the signal has been lost (e.g., due to component failure) and can begin transmitting an identification signal (e.g., a “ping”). The identification signal transmitted by the beacon may then be used to identify the location of the faulty component for servicing.Type: ApplicationFiled: July 20, 2016Publication date: January 25, 2018Inventors: Matthew P.

Publication number: 20180027468Abstract: Embodiments of the present invention provide techniques for load balancing in a network environment. A wireless networking system can include a load balancer to determine how to distribute client devices across available channels to minimize interference and maximize bandwidth. A client device can access a wireless network through an access point. When a request is received from the client device to access the wireless network, the wireless networking system can determine device information associated with the device. For example, the request can include a device identifier. In some embodiments, account information, such as a user name and password, may be included with the request or received in response to a log-in prompt. In some embodiments connection information may also be determined. Based on the device information and the connection information, the client device can be assigned to a channel.Type: ApplicationFiled: July 20, 2016Publication date: January 25, 2018Inventors: Matthew P. Pasulka, Andrew Robert Bell

Publication number: 20180027506Abstract: Embodiments of the present invention provide techniques for power management in a network environment. A wireless networking system can include various access points in different areas of a deployment environment. Each access point may include a power manager which determines a transmission power for the access point to minimize interference with neighboring access points. The power manager can determine zones associated with each access point based on the signal strength of devices within those zones and assign each zone to a separate channel. When a request is received from a client device to access the wireless network, the client device can be assigned to a channel based on connection information associated with the client device, such as signal strength or error rate. The connection information of each client device can be monitored periodically and the client devices can be reassigned to different channels based on changes to the connection information.Type: ApplicationFiled: July 20, 2016Publication date: January 25, 2018Inventors: Matthew P. Pasulka, Andrew Robert Bell

Publication number: 20140193002Abstract: One embodiment of the present invention sets forth a system that includes a detection device and a processor. The detection device is configured to sense that a handheld device has not been placed on or near a surface. In response to sensing that the handheld device has not been placed on or near a surface, the detection device is configured to transmit an indicator to the processor. The processor is configured to receive a first audio signal, and determine that the handheld device has not been placed on or near a surface by receiving the indicator from the detection device. In response to determining that the handheld device has not been placed on or near a surface, the processor is further configured to apply a compensating function to the first audio signal to generate a second audio signal, and transmit the second audio signal to a speaker.Type: ApplicationFiled: December 12, 2013Publication date: July 10, 2014Applicant: NVIDIA CORPORATIONInventors: Nikhil SATISH, David DIGNAM, Andrew Robert BELL, Shaoming FENG, Tao XIE
