Publication number: 20230152910Abstract: A wireless network device comprises a wireless signal driver, an application-driver framework that includes a bidirectional interface and an application interface. The application-driver framework is configured for application-agnostic and driver-agnostic communication. The bidirectional interface communicatively couples the wireless signal driver to the application-driver framework. The bidirectional interface includes an abstraction layer via which driver-agnostic command signals and driver-agnostic event signals are communicated with the application-driver framework and via which driver-specific command signals and driver-specific event signals are communicated with the wireless signal driver. The application interface is configured to interface with applications and with the application-driver framework.Type: ApplicationFiled: January 17, 2023Publication date: May 18, 2023Applicant: SEMICONDUCTOR COMPONENTS INDUSTRIES, LLCInventors: Qiang WANG, Marianna CARRERA, Kan HU, Haibo CHEN, Ambroise POPPER

Patent number: 10142882Abstract: A network gateway comprises a buffer and a transmission module that is configured to transmit packets of a data stream from a source device to a user device via a network medium. The packets of the data stream are received from the source device by an uplink connection between the source device and the gateway, the packets are temporarily stored in the buffer and the packets are transmitted from the buffer to the user device by a downlink connection between the user device and the gateway, such that the downlink connection depends on the uplink connection. Furthermore, the network gateway comprises a protection module that is configured to provide a protection of the uplink connection, wherein access to the network medium is reserved for the packets of the data stream of the uplink connection.Type: GrantFiled: December 21, 2012Date of Patent: November 27, 2018Assignee: Thomson LicensingInventors: Marianna Carrera, Nidhi Hegde, Martin May

Patent number: 9756450Abstract: A system for automating setup of a station on one among a plurality of wireless home networks each associated with a distinct subscriber and each including a wireless access point (WAP) node supporting wireless communications with an associated set of station nodes. A station provisioner circuit couples to the WAP nodes to acquire credentials for a new station prior to delivery to an identified one of the subscribers; and to inject the acquired credentials into a corresponding one of the WAP nodes which services the wireless network of the identified one of the subscribers. A secure link management circuit on the corresponding one of the WAP nodes utilizes the acquired credentials from the station provisioner circuit for identification of the new station shipped to the identified subscriber; and for setup of a secure wireless communication link between the new station and the corresponding WAP node which services the subscriber's wireless home network.Type: GrantFiled: August 25, 2016Date of Patent: September 5, 2017Assignee: Quantenna Communications, INC.Inventors: Marianna Carrera, Debashis Dash, Bahador Amiri
